[lvm-devel] [PATCH] handle transient errors in lvconvert --repair

[Petr Rockai]

Hi,

this is a first iteration of the transient-error handling in
lvconvert. This works by marking LVs as partial even though there are no
PVs missing -- whenever a mirror marks a leg or log as failed (in the
status string). The downside of this approach is that we never figure
which PV is failing, but that would require kernel-level support for IO
error tracking.

Yours,
   Petr.

PS: The test is rather rudimentary. On one hand, testing log failures
seems impossible because that runs into kernel lockups. I will add more
test scenarios for leg failures later, and also for leg replacement.
