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.

oster | Revision 1.104 actually fixed the issues that were preventing
us from freeing the ReconControl structures. So free them
and thus also prevent a panic on shutdown due to items not
being correctly returned to the pool.
Thanks to manu@ for report of the panic, and for initial testing
of the changes.

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.

Fix a long long-standing off-by-one error in computing lastPSID.
SUsPerPU is only really supported for a value of 1, and since the

callbacks.

oster | branches: 1.121.12; 1.121.20;
Fix a long-standing bug related to rebooting while a
reconstruct-to-spare is underway but not yet complete.
The issue was that a component was being marked as a used_spare when
the rebuild started, not when the rebuild was actually finished.
Marking it as a used_spare meant that the component label on the spare
was being updated such that after a reboot the component would be
considered up-to-date, regardless of whether the rebuild actually
completed!
This fix includes:
1) Add an additional state "rf_ds_rebuilding_spare" which is used
to denote that a spare is currently being rebuilt from the live
components.
2) Update the comments on the disk states, which were out-of-sync
with reality.
3) When rebuilding to a spare component, that spare now enters the
state rf_ds_rebuilding_spare instead of the state rf_ds_used_spare.
4) When the rebuild is actually complete then the spare component
enters the rf_ds_used_spare state. rf_ds_used_spare is now used
exclusively for the case where the rebuilding to the spare has
completed successfully.
XXX: Someday we need to teach raidctl(8) about this new state, and
take out the backwards compatibility code in rf_netbsdkintf.c (see
RAIDFRAME_GET_INFO in raidioctl()). For today, this fix needs to be
generic enough that it can get backported without major grief.
XXX: Needs pullup to netbsd-5*, netbsd-6*, and netbsd-7

Add logic to the main reconstruction loop to handle RAID5 with rotated
spares. While here, observe that we were actually doing one more
stripe than we thought we were, and correct that too (it didn't matter
for non-RAID5_RS, but it definitely does for RAID5_RS). Add some
bounds-checking at the beginning to handle the case where the number
of stripes in the set is smaller than the sliding reconstruction window.

Introduce struct pathbuf. This is an abstraction to hold a pathname
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.
Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).
The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.

Finally commit 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.
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
project, assorted developers for trying very hard to break it, and
probably more I'm forgetting.

oster | If we see a RF_RECON_WRITE_ERROR event we know a write has finished and
we need to account for that. Failure to do so means we can end up
waiting forever for writes we think are outstanding, but which have
already completed.

Re-work some of the guts of the reconstruction code.
Reconmap used to have one pointer for every reconstruction unit. This
does not scale well in the land of 1TB disks, where some 100MB+ of
"status pointers" are required for typical configurations. Convert
the reconstruction code to use a "sliding status window" which will
scale nicely regardless of the number of stripes/reconstruction units
in the RAID set. Convert the main reconstruction loop to rebuild the
array in chunks rather than in one big lump.
As part of these changes, introduce a function to kick any waiters on
the head separation callback list, and use that in the main
reconstruction event queue to wake up the waiters if things have
stalled. (I believe this may fix a race condition that could occur at
at least at the very end of a disk during reconstruction under heavy
IO load.)
Thanks to Brian Buhrow for all his help, support, and patience in
testing these changes.

A forced recon read should not default to indicating that the reads
for that disk have stopped, since this will bump us out of the normal
reconstruction loop prematurely.
Fixes the (mostly cosmetic) bug where the reconstruction
status values stop updating, and from raidctl it appears that
reconstruction has totally stalled (which it actually hasn't -- the
reconstruction does complete properly, but not in the normal way).

cube | Change dk_lookup() to accept an additional argument of the type enum uio_seg
that tells whether the given path is in user space or kernel space, so it
can tell NDINIT().
While the raidframe calls were ok, both ccd(4) and cgd(4) were passing
pointers to user space data, which leads to strange error on i386, as
reported by Jukka Salmi on current-users.
The issue has been there since last august, I'm actually a bit surprised
that no one in the meantime has used ccd(4) or cgd(4) on an arch where it
would have simply faulted.

oster | If rf_SubmitReconBuffer indicates the submission was blocked (for
whatever reason), return 0 instead of the default
RF_RECON_READ_STOPPED. Returning RF_RECON_READ_STOPPED would result
in rf_ContinueReconstructFailedDisk() thinking that the given
component was "done" and breaking out of the main reconstruction loop
far too early. Reconstruction still worked correctly as long as there
were no errors, but RAIDframe wouldn't be in a position to properly
handle read/write errors during reconstruction.
This fixes the "raidctl's progress bar spins at 0% until
reconstruction finishes" problem.

oster | Vastly improve the error handling in the case of a read/write error
that occurs during a reconstruction. We go from zero error handling
and likely panicing if something goes amiss, to gracefully bailing and
leaving the system in the best, usable state possible.
- introduce rf_DrainReconEventQueue() to allow easy cleaning of the
reconstruction event queue
- change how we cleanup the floating recon buffers in
rf_FreeReconControl(). Detect the end of the list rather
than traversing according to a count.
- keep track of the number of pending reconstruction writes. In the
event of a read error, use this to wait long enough for the pending
writes to (hopefully) drain.
- more cleanup is still needed on this code, but I didn't want to
start mixing major functional changes with minor cleanups.
XXX: There is a known issue with pool items left outstanding due to
the IO failure, and this can show up in the form of a panic at the
tail end of a shutdown. This problem is much less severe than before
these changes, and the hope/plan is that this problem will go away
once this code gets overhauled again.

oster | - don't use rf_PrintUserStats() for recon statistics.
rf_PrintUserStats() was mean for the simulator, and doesn't provide

Reconstructing actually renders the stats even more useless, since it
resets them all to zero before the reconstruct starts!

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.

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.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
|
| 1.55 |
| 28-Jun-2003 |
darrenr | Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V

oster | Everyone and their dog was using RF_ERRORMSG3 to print out the same
sort of error message, over and over again, in different files.
Rather than having the same text repeated in multiple .o files,
create a couple of little functions to do the printing, and save a
bundle of space. Also improves readability of code.

oster | Be more aggressive about updating component labels in the event
of a real component failure (or a simulated failure):

real or simulated.

- re-work incorrect component configuration code
- re-work disk configuration code
- cleanup initial configuration of raidPtr info
- add auto-detection of components and RAID sets (Disabled, for now)
- allow / on RAID sets (Disabled, for now)
- rename "config_disk_queue" to "rf_ConfigureDiskQueue" and properly prototype
in rf_diskqueue.h
- protect some headers with #if _KERNEL (XXX this needs to be fixed properly)
and cleanup header formatting.

A forced recon read should not default to indicating that the reads
for that disk have stopped, since this will bump us out of the normal
reconstruction loop prematurely.
Fixes the (mostly cosmetic) bug where the reconstruction
status values stop updating, and from raidctl it appears that
reconstruction has totally stalled (which it actually hasn't -- the
reconstruction does complete properly, but not in the normal way).

If rf_SubmitReconBuffer indicates the submission was blocked (for
whatever reason), return 0 instead of the default
RF_RECON_READ_STOPPED. Returning RF_RECON_READ_STOPPED would result
in rf_ContinueReconstructFailedDisk() thinking that the given
component was "done" and breaking out of the main reconstruction loop
far too early. Reconstruction still worked correctly as long as there
were no errors, but RAIDframe wouldn't be in a position to properly
handle read/write errors during reconstruction.
This fixes the "raidctl's progress bar spins at 0% until
reconstruction finishes" problem.

scale nicely regardless of the number of stripes/reconstruction units
in the RAID set. Convert the main reconstruction loop to rebuild the
array in chunks rather than in one big lump. May fix bin/38471.

sys/dev/raidframe/rf_reconstruct.c: revision 1.103
A forced recon read should not default to indicating that the reads
for that disk have stopped, since this will bump us out of the normal
reconstruction loop prematurely.
Fixes the (mostly cosmetic) bug where the reconstruction
status values stop updating, and from raidctl it appears that
reconstruction has totally stalled (which it actually hasn't -- the
reconstruction does complete properly, but not in the normal way).

Change dk_lookup() to accept an additional argument of the type enum uio_seg
that tells whether the given path is in user space or kernel space, so it
can tell NDINIT().
While the raidframe calls were ok, both ccd(4) and cgd(4) were passing
pointers to user space data, which leads to strange error on i386, as
reported by Jukka Salmi on current-users.

Fix a long-standing bug related to rebooting while a
reconstruct-to-spare is underway but not yet complete.
The issue was that a component was being marked as a used_spare when
the rebuild started, not when the rebuild was actually finished.
Marking it as a used_spare meant that the component label on the spare
was being updated such that after a reboot the component would be
considered up-to-date, regardless of whether the rebuild actually
completed!
This fix includes:
1) Add an additional state "rf_ds_rebuilding_spare" which is used
to denote that a spare is currently being rebuilt from the live
components.
2) Update the comments on the disk states, which were out-of-sync
with reality.
3) When rebuilding to a spare component, that spare now enters the
state rf_ds_rebuilding_spare instead of the state rf_ds_used_spare.
4) When the rebuild is actually complete then the spare component
enters the rf_ds_used_spare state. rf_ds_used_spare is now used
exclusively for the case where the rebuilding to the spare has
completed successfully.
XXX: Someday we need to teach raidctl(8) about this new state, and
take out the backwards compatibility code in rf_netbsdkintf.c (see
RAIDFRAME_GET_INFO in raidioctl()). For today, this fix needs to be
generic enough that it can get backported without major grief.
XXX: Needs pullup to netbsd-5*, netbsd-6*, and netbsd-7

Add logic to the main reconstruction loop to handle RAID5 with rotated

stripe than we thought we were, and correct that too (it didn't matter
for non-RAID5_RS, but it definitely does for RAID5_RS). Add some
bounds-checking at the beginning to handle the case where the number
of stripes in the set is smaller than the sliding reconstruction window.

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.
