pvetest kvm snapshot

[RobFantini]

On a test system, I've this kvm:

boot: c
bootdisk: ide0
cores: 2
cpu: host
cpuunits: 3000
ide0: fbc73vg:vm-6103-disk-1
ide1: fbc73vg:vm-6103-disk-2
ide2: none,media=cdrom
memory: 512
name: etch-kvm
net0: e1000=42:B5:48:4E:15:6A,bridge=vmbr0
onboot: 1
ostype: l26
sockets: 1

when I try to make a snapshot from pve :

TASK ERROR: can't snapshot volume 'fbc73vg:vm-6103-disk-2'

does the snapshot fail due to the kvm having more then one disk?

I just tried a snapshot on a kvm containing one disk [ I restored one to do the test ] , and got the same result:

TASK ERROR: can't snapshot volume 'fbc73vg:vm-9999-disk-1'

snapshot doesn't work with lvm yet.

storage that work : qcow2 file ,sheepdog, rbd, nexenta

Hi Spirit,
nexenta mean normal lvm ontop of nexenta-iscsi with an enhanced version of this http://forum.proxmox.com/threads/74...hots-functions-in-proxmox-2?p=42391#post42391 ??

Does it's also work with multible vm-hdds on different iSCSI-LUNs (all from nexenta-store)?

no lvm, direct scsi lun.

we manage nexenta volume creation,iscsi lun assignment,snapshots with nexenta api)

they are a nexenta plugin in testing if you want to test.

Hi,
thanks for the info. No I can't test because I don't have nexenta-storage yet, but we need in the next future new storage and for this reason it's good to know what's usable and what not.

I made a small wiki (need to be polished)

http://pve.proxmox.com/wiki/Storage:_Nexenta

you can download the community edition for testing, free up to 18TB of storage.
