Raid
RAID
previously 2 600GB SAS disks were in RAID1 in the same volumegroup.
I have no spare disk, nor do I want to spend money on old tech.
Reconfigure : each disk is within own volume group, no more RAID, more (free) space. Tool would not let me otherwise.
No more raid :
machine on one disk are backupped to other disk, and vice versa one disk remains VG (volume group) within proxmox : used for LXC en VM images, backup other disk contains ext4 filesystem and is a directory
