This patch supports LSI/Engenio devices in RDAC mode. Like dm-emc
it requires userspace support. In your multipath.conf file you must have:path_checker rdac
hardware_handler "1 rdac"
prio_callout "/sbin/mpath_prio_tpc /dev/%n"And you also then must have a updated multipath tools release which
has rdac support.Signed-off-by: Chandra Seetharaman

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.)Signed-off-by: Jonathan Brassow

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.Signed-off-by: Jonathan Brassow

This patch causes device-mapper to reject any barrier requests. This is done
since most of the targets won't handle this correctly anyway. So until the
situation improves it is better to reject these requests at the first place.
Since barrier requests won't get to the targets, the checks there can be
removed.Cc: stable@kernel.org

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().Signed-off-by: Jonathan Brassow

Allow invalid snapshots to be activated instead of failing.
This allows userspace to reinstate any given snapshot state - for

Process persistent exception store metadata IOs in a separate thread.
A snapshot may become invalid while inside generic_make_request().
A synchronous write is then needed to update the metadata while still
inside that function. Since the introduction of
md-dm-reduce-stack-usage-with-stacked-block-devices.patch this has to
be performed by a separate thread to avoid deadlock.Signed-off-by: Milan Broz
