Hallo,

im Proxmox-System werden die Backups regelmäßig im Snapshot-Modus Taskgesteuert erstellt.

Bei einem LXC-System funktioniert der Snapshotmodus nicht: mode failure - some volumes do not support snapshots

Hier die Configuration vom betroffenem System:
arch: amd64
cores: 1
features: mount=nfs;cifs
hostname: vpn
memory: 4096
mp0: /mnt/net-share,mp=/mnt/net-share
mp1: /mnt/NAS,mp=/mnt/NAS
net0: name=eth0,bridge=vmbr0,hwaddr=XX:XX:XX:XX:XX:XX,ip=dhcp,ip6=auto,type=veth
net1: name=tun0,bridge=vmbr1,hwaddr=YY:YY:YY:YY:YY:YY,type=veth
onboot: 1
ostype: debian
rootfs: local:323/vm-323-disk-1.raw,size=8G
swap: 512
lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file 0 0

Log-Auszug vom Backup:
INFO: starting new backup job: vzdump 323 --mode snapshot --remove 0 --storage BackupNet --compress lzo --node proxmox
INFO: filesystem type on dumpdir is 'cifs' -using /var/tmp/vzdumptmp7886 for temporary files
INFO: Starting Backup of VM 323 (lxc)
INFO: Backup started at 2019-05-26 14:46:57
INFO: status = running
INFO: CT Name: vpn
INFO: excluding bind mount point mp0 ('/mnt/net-share') from backup
INFO: excluding bind mount point mp1 ('/mnt/NAS') from backup
INFO: mode failure - some volumes do not support snapshots
INFO: trying 'suspend' mode instead
INFO: backup mode: suspend
INFO: ionice priority: 7
INFO: CT Name: vpn
INFO: excluding bind mount point mp0 ('/mnt/net-share') from backup
INFO: excluding bind mount point mp1 ('/mnt/NAS') from backup
INFO: starting first sync /proc/1300/root// to /var/tmp/vzdumptmp7886

An der letzten Zeile bleibt der backup-Task hängen. Das LXC hat während dessen den Status "Frozen".

Im Backup-Pool sind ausreichend freie Kapazitäten vorhanden.

Erst nach dem Abbrechen des Backup-Tasks läuft das LXC-System weiter.

Hat jemand einen Idee, wie die Ursache eingegrenzt werden kann?
