Hello linux-raid
I am running a server that runs a number of virtual machines and manages
their virtual disks as logical volumes using lvmraid (so: indivdual SSDs
are used as PVs for LVM; the LVs are using RAID to create redundancy and
are created with commands such as "lvcreate --type raid5 --stripes 4
--stripesize 128 ...")
The server is running Debian 10 "buster" with latest updates and its
stock kernel: Linux (hostname) 4.19.0-17-amd64 #1 SMP Debian 4.19.194-3
(2021-07-18) x86_64 GNU/Linux
Ummm is there an lvm mailing list? I've not seen a question like this
before - this list is really for md-raid. There may be people who can
help but I've got a feeling you're in the wrong place, sorry.
In md terms, volumes have an "event count", and that error sounds like
one drive has been lost, and the others do not have a matching event
count. Hopefully that's given you a clue. With mdadm you'd do a forced
assembly, but it carries the risk of data loss.
Cheers,
