<div class="moz-cite-prefix">Hi,<br>
<br>
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. <br>
<br>
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 .<br>
<br>
Cheers<br>

<div class="moz-cite-prefix">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: <a moz-do-not-send="true"

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