[SOLVED] rbd ... object map is invalid

[RobFantini]

for some LXC's there have had ' object map is invalid' since about 2020 .

the timestamps show these lines are created when a pbs backup occurs.

I assume these are harmless. Is there is a simple way to prevent these ?

You could try the command rbd object-map rebuild <IMAGE> [0].

thank you Mira, that fixed the warning.

rbd -p <pool-name> object-map rebuild vm-160-disk-0
