[linux-lvm] LVM RAID5 out-of-sync recovery

[Giuliano Procida]

Slava, the main problem I had was that LVM forbade many operations
while I had a PV missing.

In your case, apparently, all PVs are present. So I suggest the following:

1. examine the recent history in /etc/lvm/archive
2. diff each transition and see if you can understand what has
happened at each stage
3. vgcfgrestore the most recent version that you think will allow you
to activate your array, you can work backwards incrementally
4. check kernel logs!
5. scrub (resync) the array if needed

Hope this helps,
Giuliano.
