[SOLVED] Backup failed unable to open file Permission denied

[trollmars]

Hi,

benutze noch PVE 6.2.Dazu der PBS.
Wollte jetzt mal upgraden auf 7.

Mein Backup geht von den meisten CTs und VMs auf einen PBS. Das lief auch bi gestern hervorragend !

Jetzt wollte ich bevor ich upgrade ein 2 Node Cluster erstellen,
Um wichtige CT/VMs auf einen anderen Node zu haben falls das Upgrade auf 7 auf dem Haupt Node fehl schlägt.

Jetzt zum Problem.
Es gehen keine Backups mehr auf den PBS,
Wenn ich manuell via GUI trigggere kommt (hier CT 202):

INFO: starting new backup job: vzdump 202 --mode snapshot --remove 0 --node pve-main --storage PBS-Main
INFO: Starting Backup of VM 202 (lxc)
INFO: Backup started at 2022-09-07 23:33:45
INFO: status = running
ERROR: Backup of VM 202 failed - unable to open file '/etc/pve/nodes/pve-main/lxc/202.conf.tmp.32010' - Permission denied
INFO: Failed at 2022-09-07 23:33:45
INFO: Backup job finished with errors
TASK ERROR: job errors

Woher kommt das?
Es muss ja irgendwas mit dem Cluster zutun haben.

Hi,

what does pvecm status report? I'd also like to point out that running a two node cluster isn't recommended and if you don't want to add a third node, please think about setting up a QDevice [1].

Hi,
Thx!

I figured out that my now offlline node 2 causes the problem.
I do "pvecm expected 1" and now the backup to PBS works as aspected.
Meanwhile i do "pvecm delnode node 2".

Thx for the Qdevice.
But i guess i go the road to pve 7.2 with a second pve as Standalone,
rebuild important VMs and CTs on it and do then upgrade my main PVE to 7,2.

THX

Hey,

this is likely a different issue, can you please open a new thread and not revive threads that have been closed for a year and a half?

Thanks!
