i'm having an issue with my backups on 1.9... Its happening on all my KVM boxes... the HDDs are set to RAW.


101: Feb 29 02:00:02 INFO: Starting Backup of VM 101 (qemu)
101: Feb 29 02:00:02 INFO: running
101: Feb 29 02:00:02 INFO: status = running
101: Feb 29 02:00:02 INFO: mode failure - unable to detect lvm volume group
101: Feb 29 02:00:02 INFO: trying 'suspend' mode instead
101: Feb 29 02:00:02 INFO: backup mode: suspend

On this box it takes over an hour to run the backup...

Any suggestions on how to enable snapshot mode?

I've now got the server hosted on NFS on one SAN, and the backup running to an NFS share running on another SAN but this hasn't made any difference apart from making my backups a little more useful if the primary SAN failed.

You cannot do snapshots if your disk images are on a nfs share.

you use wrong definitions - nfs is NAS (network attached storage), SAN is block storage (check Wikipedia for all details about these definitions).

in order to get snapshot running you need SAN via iSCSI or FC (with LVM) but also local storage works.
 
with iSCSI, is it best to have an iSCSI per VM or an iSCSI assigned for the Proxmox server to store the VM images?
