no storage available for backups

[spergberger]

Hi all.

I have a big software RAID disk I'm using for Longhorn volumes but I'd like to use it to backup VMs as well. The entire RAID5 device appears as a single volume group when I browse
Datacenter
pve1
Disks
LVM
sataraid
and the Longhorn volumes show up as /dev/sataraid/vm-102-disk-0, /dev/sataraid/vm-103-disk-0 etc.

My storage.cfg is below. I appended ",backup" to the content line and ran 'systemctl daemon-reload' but the device is not available for backups in the GUI. Is there another daemon I need to reload? Do I need to create a big logical volume using shell commands to hold all my future backups?

dir: local
path /var/lib/vz
content vztmpl,iso
lvmthin: local-lvm
thinpool data
vgname pve
content images,rootdir
lvm: nvme1
vgname vm0
content images,rootdir
saferemove 0
shared 0
lvm: md0
vgname sataraid
content rootdir,images,backup
saferemove 0
shared 0

I tried running

pvesm set md0 --disable 0
and saw the error:
storage does not support content type 'backup'

OK. Needs to be a 'directory.' So I created a logical volume and wrote a xfs filesystem to it then mounted it.
/etc/pve/storage.cfg has these lines now:

dir: backup
path /mnt/backup
content images,rootdir,backup
