dm raid1: handle log failure

When writing to a mirror, the log must be updated first.  Failure
to update the log could result in the log not properly reflecting
the state of the mirror if the machine should crash.

We change the return type of the rh_flush function to give us
the ability to check if a log write was successful.  If the
log write was unsuccessful, we fail the writes to avoid the
case where the log does not properly reflect the state of the
mirror.

A follow-up patch - which is dependent on the ability to
requeue I/O's to core device-mapper - will requeue the I/O's
for retry (allowing the mirror to be reconfigured.)

13 years agodm raid1: handle resync failures
Jonathan Brassow [Thu, 12 Jul 2007 16:29:04 +0000 (17:29 +0100)]
dm raid1: handle resync failures

Device-mapper mirroring currently takes a best effort approach to
recovery - failures during mirror synchronization are completely ignored.
This means that regions are marked 'in-sync' and 'clean' and removed
from the hash list.  Future reads and writes that query the region
will incorrectly interpret the region as in-sync.

This patch handles failures during the recovery process.  If a failure
occurs, the region is marked as 'not-in-sync' (aka RH_NOSYNC) and added
to a new list 'failed_recovered_regions'.

Regions on the 'failed_recovered_regions' list are not marked as 'clean'
upon removal from the list.  Furthermore, if the DM_RAID1_HANDLE_ERRORS
flag is set, the region is marked as 'not-in-sync'.  This action prevents
any future read-balancing from choosing an invalid device because of the
'not-in-sync' status.

If "handle_errors" is not specified when creating a mirror (leaving the
DM_RAID1_HANDLE_ERRORS flag unset), failures will be ignored exactly as they
would be without this patch.  This is to preserve backwards compatibility with
user-space tools, such as 'pvmove'.  However, since future read-balancing
policies will rely on the correct sync status of a region, a user must choose
"handle_errors" when using read-balancing.

Jonathan Brassow [Thu, 12 Jul 2007 16:28:25 +0000 (17:28 +0100)]
dm raid1: clear region outside spinlock

A clear_region function is permitted to block (in practice, rare) but gets
called in rh_update_states() with a spinlock held.

The bits being marked and cleared by the above functions are used
to update the on-disk log, but are never read directly.  We can
perform these operations outside the spinlock since the
bits are only changed within one thread viz.
   - mark_region in rh_inc()
   - clear_region in rh_update_states().

So, we grab the clean_regions list items via list_splice() within the
spinlock and defer clear_region() until we iterate over the list for
deletion - similar to how the recovered_regions list is already handled.
We then move the flush() call down to ensure it encapsulates the changes
which are done by the later calls to clear_region().

The patch also ensures that the CPSR.A bit is cleared and the USR mode
is set if the CPU does not support the 26bit user mode.

[ARM] pxa: remove boot time RTC initialisation

The RTC library code contains everything necessary to set the
system time from the RTC; for similar reasons as the previous
commit, it's far better to let the RTC library code sort this
out rather than implement something which might not be
appropriate for everyone.

[ARM] pxa: stop doing our own rtc management over suspend

Remove the RTC management over a suspend/resume cycle.  Firstly,
we may not be using the internal RTC for time keeping; some
platforms have an external RTC for this inspite of the PXA having
an internal RTC.  Secondly, the RTC library code handles updating
system time on resume.
