oster | We no longer need the deprecated copyback functionality now that
incorporating a used spare is automatic.
Copyback has always been an issue, as to do a copyback all IO to
the array had to be suspended, and so was very, very unlikely to
have been used in anything resembling a production system.

oster | Implement hot removal of spares and components. From manu@.
Implement a long desired feature of automatically incorporating
a used spare into the array after a reconstruct.
Given the configuration:
Components:
/dev/wd0e: failed
/dev/wd1e: optimal
/dev/wd2e: optimal
Spares:
/dev/wd3e: spare
Running 'raidctl -F /dev/wd0e raid0' will now result in the
following configuration after a successful rebuild:
Components:
/dev/wd3e: optimal
/dev/wd1e: optimal
/dev/wd2e: optimal
No spares.
Thanks to manu@ for the development of the initial set of changes
which allowed the changes to automatically incorporate a used spare
to come to fruition. Thanks also to manu@ for useful discussions
about and additional testing of these changes.

raidframe: reject invalid values for numCol and numSpares
numCol and numSpares are "int" so they can be "-1" internally,
which means negative values need to be rejected, as well as
values higher than RF_MAXCOL/RF_MAXSPARES.
explicitly nul-terminate all strings coming from userland.
some minor CSE that avoids signed arith.
this fixes issues in the RAIDFRAME_ADD_HOT_SPARE,
RAIDFRAME_CONFIGURE, RAIDFRAME_DELETE_COMPONENT,
RAIDFRAME_INCORPORATE_HOT_SPARE, and RAIDFRAME_REBUILD_IN_PLACE
ioctl commands.

oster | All IO is async in the RAIDframe kernel driver, so desc->async_flag
isn't needed. Cleanup the flag from rf_DoAccess() and its caller as
well.

| 23-Jul-2021 |
oster | Extensive mechanical changes to the pools used in RAIDframe.
Alloclist remains not per-RAID, so initialize that pool
separately/differently than the rest.
The remainder of pools in RF_Pools_s are now per-RAID pools. Mostly
mechanical changes to functions to allocate/destroy per-RAID pools.
Needed to make raidPtr available in certain cases to be able to find
the per-RAID pools.
Extend rf_pool_init() to now populate a per-RAID wchan value that is
unique to each pool for a given RAID device.
TODO: Complete the analysis of the minimum number of items that are
required for each pool to allow IO to progress (i.e. so that a request
for pool resources can always be satisfied), and dynamically scale
minimum pool sizes based on RAID configuration.

mrg | support different endian raidframe component label.
there are two on-disk formats in use in raidframe:
- the component label
- the parity map
the parity map is a bitmap implemented as bytes, so it has no
endian issue. the component label is the problem, as most of
the fields are 32 bit. this change only supports version 2 of
raidframe (active since the year 2000.)
as component labels are read and used before a raidPtr for the
raid set has been created, there is no obvious storage for the
swapped indicator, so the in-core version remains the on-disk
version, while the rest of in-core label is swapped.
in raidread_component_label() and raidwrite_component_label(),
check if the swapped version, and if so, call new rf_swap_label()
and ensure that the in-core label is native-byte order. for the
write method, an on-stack copy is modified before writing, so
that the in-core version remains valid. (this stack usage is
below other stack usage in similar functions here.)
adjust the label ioctls RAIDFRAME_GET_COMPONENT_LABEL and
RAIDFRAME_GET_COMPONENT_LABEL80 to return the byte-swapped
version so that eg, raidctl -s reports the right version.
when performing final configuration of a raidset, report if a
label swapped, and also complain if there are differently swapped
versions on the other components.
tested on arm64, sparc64 and amd64

fix the function pointer and callback mess:
- callback functions return 0 and their result is not checked; make them void.

fixes the i386 ALL build with clang which complained about the

mrg | fix a problem in half-configured raid devices, found when a "raidctl -c"
failed, and a "raidctl -C" was run afterwards, triggering mutex locking
issues. fix this by moving alloc and destroy of mutex/condvar for a
raid device into separate functions, and call the destroy function from
the DO_RAID_FAIL() macro.

| 11-May-2011 |
mrg | convert the main raidPtr mutex to a kmutex, and add a couple of cv's to
cover the old sleep/wakeup points for adding_hot_spare and waitForReconCond.
convert all remaining simple_lock's to kmutexes (they're not used or compiled
right now... even with all options enabled) and remove the support for them.
this leaves just a pair of tsleep()/wakeup() calls using old scheduling APIs.

- convert rf_rad_lock and the per-raid "cv" to per-raid kmutex/and real cv
- use rf_mutex_init() in places, and move it with the similar definitions
|
| 1.125 |
| 27-Apr-2011 |
mrg | prepare to convert more raidframe old lock/sleep APIs to mutex/condvar:
- remove RF_DECLARE_EXTERN_MUTEX and RF_DECLARE_STATIC_MUTEX, the qualifier
can be provided at the use point with the normal define
- rename the *LGMGR_MUTEX() macros to *mutex2() names, and add some more
defines for use:
rf_declare_mutex2()
rf_declare_cond2()
rf_lock_mutex2()
rf_unlock_mutex2()
rf_init_mutex2()
rf_destroy_mutex2()
rf_init_cond2()
rf_destroy_cond2()
rf_wait_cond2()
rf_signal_cond2()
rf_broadcast_cond2()
- use the new names for the configureMutex(), which previous used some combo
of direct mutex* calls and macros
- convert the node_queue to use a mutex/cv combo
- in rf_ShutdownEngine() and DAGExecutionThread(), also signal the former from
the latter when it is done and about to exit
- convert iodone_lock to use the new macros
|
| 1.124 |
| 23-Apr-2011 |
mrg | move the iodone setup and tear down into rf_engine.c. this fixes
"raidctl -u" and should also help the case where we fail to setup
a device part of the way through.
|
| 1.123 |
| 23-Apr-2011 |
mrg | convert the iodone_lock to a mutex, and use a condvar for signalling.
this only handles the smallest use of old simple_lock/tsleep/wakeup
APIs inside raidframe, and it points out that cv(9)'s have only one
wait channel per cv, whereas each tsleep() caller can specify a
different wait channel. this change removes the difference between
normal raidio and waiting for IO during shutdown.
i've tested this one 3 systems, ran atf, and had mlelstv and rmind
review the change.

Drastically reduces the amount of time spent rewriting parity after an
unclean shutdown by keeping better track of which regions might have had
outstanding writes. Enabled by default; can be disabled on a per-set

Discussed on tech-kern@ to a general air of approval; exhortations to
commit from mrg@, christos@, and others.
Thanks to Google for their sponsorship, oster@ for mentoring the

On an idea from Thor (tls@), do not fail a component if doing so would
render the RAID set completely dead. Instead, we retry the IO a
maximum of RF_RETRY_THRESHOLD times (currently '5'), and then just
return an IO error if the IO fails. This should reduce the damage
caused by having multiple disks appear to fail when the culprit is
really something else (power, controllers, etc.)

don't continue to try to allocate more of those buffers.

oster | These changes complete the effective removal of malloc() from all
write paths within RAIDframe. They also resolve the "panics with
RAID 5 sets with more than 3 components" issue which was present
(briefly) in the commits which were previously supposed to address
the malloc() issue.
With this new code the 5-component RAID 5 set panics are now gone.
It is also now also possible to swap to RAID 5.
The changes made are:
1) Introduce rf_AllocStripeBuffer() and rf_FreeStripeBuffer() to
allocate/free one stripe's worth of space. rf_AllocStripeBuffer() is
used in rf_MapUnaccessedPortionOfStripe() where it is not sufficient to
allocate memory using just rf_AllocBuffer(). rf_FreeStripeBuffer() is
called from rf_FreeRaidAccDesc(), well after the DAG is finished.
2) Add a set of emergency "stripe buffers" to struct RF_Raid_s.
Arrange for their initialization in rf_Configure(). In low-memory
situations these buffers will be returned by rf_AllocStripeBuffer()
and re-populated by rf_FreeStripeBuffer().
3) Move RF_VoidPointerListElem_t *iobufs from the dagHeader into
into struct RF_RaidAccessDesc_s. This is more consistent with the
original code, and will not result in items being freed "too early".
4) Add a RF_RaidAccessDesc_t *desc to RF_DagHeader_s so that we have a
way to find desc->iobufs.
5) Arrange for desc in the DagHeader to be initialized in InitHdrNode().
6) Don't cleanup iobufs in rf_FreeDAG() -- the freeing is now delayed
until rf_FreeRaidAccDesc() (which is how the original code handled the
allocList, and for which there seem to be some subtle, undocumented
assumptions).
7) Rename rf_AllocBuffer2() to be rf_AllocBuffer() and remove the
former rf_AllocBuffer(). Fix all callers of rf_AllocBuffer().
(This was how it was *supposed* to be after the last time these
changes were made, before they were backed out).
8) Remove RF_IOBufHeader and all references to it.
9) Remove desc->cleanupList and all references to it.
Fixes PR#20191

oster | branches: 1.98.2;
Yesterday's fix to rf_disks.c (rev 1.51) was necessary, but not
sufficient to clobber this nasty little bug. The behaviour observed
was a panic when doing a 'raidctl -f' on a component when DAGs were
in flight for the given RAID set. Unfortunatly, the faulty behaviour
was very intermittent, and it was difficult to not only reliably
reproduce the bug (nor determine when it was fixed!) but also to even
figure out what might be the cause of the problem.
The real issue was that ci_vp for the failed component was being
set to NULL in rf_FailDisk(), but with DAGs still in flight, some
of them were still expecting to use ci_vp to determine where to
read to/write from!
The fix is to call rf_SuspendNewRequestsAndWait() from rf_FailDisk()
to make sure the RAID set is quiet and all IOs have completed before
mucking with ci_vp and other data structures. rf_ResumeNewRequests()
is then used to continue on as usual.

| 20-Mar-2004 |
oster | For each RAID set, pre-allocate a number of "emergency buffers" to be
used in the event that we can't malloc a buffer of the appropriate
size in the traditional way. rf_AllocIOBuffer() and rf_FreeIOBuffer()
deal with allocating/freeing these structures. These buffers are
stored in a list on the 'iobuf' list. iobuf_count keeps track of how
many buffers are available, and numEmergencyBuffers is the effective
"high-water" mark for the freelist. The buffers allocated by
rf_AllocIOBuffer() are stripe-unit sized, which is the maximum
size requested by any of the callers.
Add an iobufs entry to RF_DagHeader_s. Use it for keeping track of
buffers that get allocated from the free-list.
Add a "generic list" pool (VoidPointerListElement Pool) for elements
used to maintain a list of allocated memory. [It is somewhat less
than ideal to add another little pool to handle this...]
Teach rf_AllocBuffer() to use the new rf_AllocIOBuffer(). Modify
other Mallocs to use rf_AllocIOBuffer(), and to update dag_h->iobufs as
appropriate.
Update rf_FreeDAG() to handle cleanup of dag_h->iobufs.
While here, add some missing pool_destroy() calls for a number of pools.
With these changes, it should (in theory) be possible to swap on
RAID 5 sets again. That said, I've not had any success there yet --
but the last issue I saw at least wasn't in RAIDframe. :-}
[There is room for this code to become a bit more consise, but I
wanted to do a checkpoint here with something known to work :) ]

rf_PrintUserStats() was mean for the simulator, and doesn't provide
any real info in kernel-space, especially for reconstructs.
Reconstructing actually renders the stats even more useless, since it
resets them all to zero before the reconstruct starts!
- since rf_PrintUserStats() is no longer used, nuke it along with the
routines that feed it. Nothing was using this code, and if we ever
need it again, we know where to find it.

oster | Let's see... raidPtr->recon_done_procs is never set to anything

oster | _rf_create_managed_mutex() is doing just a simple:
rf_mutex_init(m)
now. The rest of the fluff is no longer needed.
It also cannot fail, so error checking on rf_create_managed_mutex()
is just wasting space.
Nuke the #define's associated with rf_create_managed_mutex().
Convert rf_create_managed_mutex(listp,m) to just rf_mutex_init(m).
Remove wasteful "error checking" and simplify all instances where this
is called. (another 0.3K saved in the binary, but the real savings
is in code readability!)

oster | init_rad() and clean_rad() really do..... very little.. and only serve
to make things look far more complicated than they really are. It was
also impossible for any of the mutex/cond initializations in
init_rad() to actually fail, making the "error detection code"
unneeded. Collapse the little work done by init_rad into
rf_AllocRaidAccDesc(), and nuke init_rad() and clean_rad(). Save
another 0.25K in GENERIC.
[To be accurate/complete, init_rad() and clean_rad() *ARE* used in the
simulator version of RAIDframe. But we're so far removed from that
now that there is no point pretending otherwise.]

| 29-Dec-2003 |
oster | - first kick at a major reworking of RAIDframe's memory allocation code:
- all freelists converted to pools
- initialization of structure members in certain cases where
code was relying on specific allocation and usage properties
to keep structures in a "known state" (that doesn't work with
pools!).
- make most pool_get() be "PR_WAITOK" until they can be analyzed
further, and/or have proper error handling added.
- all RF_Mallocs zero the space returned, so there is no difference
between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s
do is tend to do is get things horribly confused.
Make RF_Malloc() the "general memory allocator", with
RF_MallocAndAdd() the "general memory allocator with
allocation list".
- some of these RF_Malloc's et al. are destined to disappear.
- remove rf_rdp_freelist entirely (it's not used anywhere!)
- remove: #include "rf_freelist.h"
- to the files that were relying on the above, add: #include "rf_general.h"
- add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy
about the loss of: #include "rf_freelist.h".
This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now
weighs in at about 162K on i386.
|
| 1.72 |
| 29-Dec-2003 |
oster | [Having received a definite lack of strenuous objection, a small amount
of strenuous agreement, and some general agreement, this commit is
going ahead because it's now starting to block some other changes I
wish to make.]
Remove most of the support for the concept of "rows" from RAIDframe.
While the "row" interface has been exported to the world, RAIDframe
internals have really only supported a single row, even though they
have feigned support of multiple rows.
Nothing changes in configuration land -- config files still need to
specify a single row, etc. All auto-config structures remain fully
forward/backwards compatible.
The only visible difference to the average user should be a
reduction in the size of a GENERIC kernel (i386) by 4.5K. For those
of us trolling through RAIDframe kernel code, a lot of the driver
configuration code has become a LOT easier to read.

|
| 1.64 |
| 04-Oct-2002 |
oster | As part of the effort to get RAIDframe playing nicely with LOCKDEBUG,
rework how completed requests are handled. In particular, instead of
doing all sorts of work and locking in interrupt context, completed
requests are now queued. A new kernel thread (rf_RaidIOThread) now
handles calling rf_DiskIOComplete() and (req->CompleteFunc)() for each
completed request. There is still work to be done to make RAIDframe
LOCKDEBUG friendly, but this change is a huge step forward.

This needs to change to a queueing system later, which will provide a

Without these changes, raidframe would use 24M or more on my machine when
the buffer cache dumped all its dirty blocks. Now it uses around 200k
or so.

the malloc() issue.
With this new code the 5-component RAID 5 set panics are now gone.
It is also now also possible to swap to RAID 5.
The changes made are:
1) Introduce rf_AllocStripeBuffer() and rf_FreeStripeBuffer() to
allocate/free one stripe's worth of space. rf_AllocStripeBuffer() is
used in rf_MapUnaccessedPortionOfStripe() where it is not sufficient to
allocate memory using just rf_AllocBuffer(). rf_FreeStripeBuffer() is
called from rf_FreeRaidAccDesc(), well after the DAG is finished.
2) Add a set of emergency "stripe buffers" to struct RF_Raid_s.
Arrange for their initialization in rf_Configure(). In low-memory
situations these buffers will be returned by rf_AllocStripeBuffer()
and re-populated by rf_FreeStripeBuffer().
3) Move RF_VoidPointerListElem_t *iobufs from the dagHeader into
into struct RF_RaidAccessDesc_s. This is more consistent with the
original code, and will not result in items being freed "too early".
4) Add a RF_RaidAccessDesc_t *desc to RF_DagHeader_s so that we have a
way to find desc->iobufs.
5) Arrange for desc in the DagHeader to be initialized in InitHdrNode().
6) Don't cleanup iobufs in rf_FreeDAG() -- the freeing is now delayed
until rf_FreeRaidAccDesc() (which is how the original code handled the
allocList, and for which there seem to be some subtle, undocumented
assumptions).
7) Rename rf_AllocBuffer2() to be rf_AllocBuffer() and remove the
former rf_AllocBuffer(). Fix all callers of rf_AllocBuffer().
(This was how it was *supposed* to be after the last time these
changes were made, before they were backed out).
8) Remove RF_IOBufHeader and all references to it.
9) Remove desc->cleanupList and all references to it.

tron | Pull up revision 1.105 (requested by oster in ticket #1038):
On an idea from Thor (tls@), do not fail a component if doing so would
render the RAID set completely dead. Instead, we retry the IO a
maximum of RF_RETRY_THRESHOLD times (currently '5'), and then just
return an IO error if the IO fails. This should reduce the damage
caused by having multiple disks appear to fail when the culprit is
really something else (power, controllers, etc.)

Pull up the RAIDframe parity map Summer Of Code project.
Drastically reduces the amount of time spent rewriting parity after an
unclean shutdown by keeping better track of which regions might have had
outstanding writes. Enabled by default; can be disabled on a per-set
basis, or tuned, with the new raidctl(8) commands.

raidframe: reject invalid values for numCol and numSpares
numCol and numSpares are "int" so they can be "-1" internally,
which means negative values need to be rejected, as well as
values higher than RF_MAXCOL/RF_MAXSPARES.
explicitly nul-terminate all strings coming from userland.
some minor CSE that avoids signed arith.
this fixes issues in the RAIDFRAME_ADD_HOT_SPARE,
RAIDFRAME_CONFIGURE, RAIDFRAME_DELETE_COMPONENT,
RAIDFRAME_INCORPORATE_HOT_SPARE, and RAIDFRAME_REBUILD_IN_PLACE
ioctl commands.

Implement hot removal of spares and components. From manu@.
Implement a long desired feature of automatically incorporating
a used spare into the array after a reconstruct.
Given the configuration:
Components:
/dev/wd0e: failed
/dev/wd1e: optimal
/dev/wd2e: optimal
Spares:
/dev/wd3e: spare
Running 'raidctl -F /dev/wd0e raid0' will now result in the
following configuration after a successful rebuild:
Components:
/dev/wd3e: optimal
/dev/wd1e: optimal
/dev/wd2e: optimal
No spares.
Thanks to manu@ for the development of the initial set of changes
which allowed the changes to automatically incorporate a used spare
to come to fruition. Thanks also to manu@ for useful discussions
about and additional testing of these changes.
