Hi, how can I create a LVM snapshot of a VM?
root@heimdall:~# lvcreate -L 4G -s /dev/mapper/vg_guests-lv_jarl -n lv_snap_jarl /dev/mapper/vg_mydata Physical Volume "/dev/mapper/vg_mydata" not found in Volume Group "vg_guests" root@heimdall:~# There is no free space in 'vg_guests'. The only free space is in 'vg_mydata'. Can I create a snapshot over the network on disks an another machine? Can I extend 'vg_guests', using the free space of 'vg_mydata'? Or would I have to shrink 'vg_mydata' to have free space to be able to extend 'vg_guests' to be able to create a snapshot? I want to back up the VM without shutting it down. If it can't avoided, I could shut it down to take the backup. In that case, how would I copy the volume to get a useful backup file? I think I wish I had used btrfs ... -- Hallowed are the Debians! -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
