[PVE-User] VirtIO SCSI, trim, strange logs...

[Marco Gaiarin]

I'm using latest proxmox 4.4, daily updated by repository.

I've used VirtIO (plain) disk driver until now, but i'm experimenting
now VirtIO SCSI driver, to be able to enable trim on disks image (and
so, enabling the discard options).

So i've moved to VirtIO SCSI some ''non critical'' VMs, using different
storage (iSCSI/SAN, Ceph, local LVM Thin), and i've tested the fstrim
command, that works as expected, following that wiki page:

	https://pve.proxmox.com/wiki/Qemu_trim/discard_and_virtio_scsi


But one of these storage (LVM thin), during backup of the VMs, i've
found the log (of the guest) full of:

	May 21 20:02:49 brucaliffo kernel: [183109.860071] sd 0:0:0:0: [sda] abort

VMs work as expected now, and all seems normal.


But i prefere asking here for some clue... thanks.
