Linux LVM mailing list,
Just a quick question regarding LVM and clustered systems:
I have two RHEL6 servers that can see the same LUN via a SAN, but only
one will mount the LV (with an ext4 filesystem) at a time.
The situation is one that allows a manual failover (by mounting the
filesystem on the second server) if the first server fails.
Are there any LVM-related processes (ongoing or at bootup/shutdown) that
could run on server2 that could affect the PV/VG and/or LV that is
mounted and in use on server1?
Again I am fully aware of the dangers of concurrently mounting
filesystems in two places, but not sure if the mere visibility of the
LVM-related metadata to both servers concurrently poses any risk.
I am not using clvm, just the standard lvm.
Thanks for any advice on this.
Regards,
Marcus.
