[lvm-devel] [PATCH] lvm2: sync error handling on secondary mirror in dmeventd

[Takahiro Yasui]

Set the ME_FAILURE flag if the error is related to sync on the secondary
mirror. A sync error on the secondary mirror occurs by a write I/O and
the error can be treated as the regular write error on mirror legs.
