[PVE-User] LVM Snapshot from IBM Storage

[Gilberto Nunes]

Hello guys

I deploy a Proxmox with IBM x3560 M4 and an IBM Storage Storwize...
Everything is gonna ok.
I have mapped the LUN's and set to no use it directly.
I set LVM on top of iSCSI.
Ok... I'm unable to make snapshots through web interface.
So, I thought I were possible to take LVM Snapshot!
But not at all!
I can find the LVM disk to make the snap!

srvvirtua01:~# lvs

  pve          1   3   0 wz--n- 278.37g  16.00g

But, inside /dev/mapper/, there is no such disk vm-100-disk-1

 ls /dev/mapper/ -l
total 0
crw------- 1 root root 10, 61 Aug 21 16:28 control
lrwxrwxrwx 1 root root      7 Aug 22 11:32 mpath0 -> ../dm-4
lrwxrwxrwx 1 root root      7 Aug 22 10:53 mpath1 -> ../dm-5
lrwxrwxrwx 1 root root      7 Aug 21 16:28 pve-data -> ../dm-2
lrwxrwxrwx 1 root root      7 Aug 21 16:28 pve-root -> ../dm-0
lrwxrwxrwx 1 root root      7 Aug 21 16:28 pve-swap -> ../dm-1

I'm using multipath... Perhaps this can interfere with LVM??

Thank you....
