Hi,
Some time ago I did some (non-extensive) tests and I didn't like what I
saw. It seemed LVM wouldn't warn when a RAID1 had a failed disk, LV
seemed to behave wrongly and so on.
If your environment allows it, I recommend to use mdraid, even if your
have to do it on different PV LVs; although it'd be better to use
disk->md->lvm .
Cheers
Eneko

I never tried this myself, but I think you'll need to use the mirror
log disk logs instead of the default disk log. Maybe this helps:

By LVM mirror i mean mirrored LV volumes, distributed on several VGs.
(PVs is iSCSI-based disks running on two separate servers)
Like RAID1.

What do you mean with LVM mirror?
- LVM on top of DRBD? - you need to use active/active
- mirroring of a specific logical volume?
- mirroring on storage hardware layer? Proxmox shouldn't care then
if you have iscsi multipathing
best regards
