WARN: warning: unable to access chunk

[flexyz]

Hi

I am running an offsite PBS in GCP that sync from a remote PBS server. When I run garbage collect, one of my volumes have tons of WARNINGS.

And I see that "/backup-pbs-gcp/shares-temp/*" was from a previous job that I later moved to another job-id and therefor do not exist anymore.

Can I just remove the folder not active anymore or??

root@pbs-offsite-gcp:~# ls -lah /backup-pbs-gcp

yeah, if shares-temp only contains index files that are not relevant to you anymore, you can delete it. the garbage collection is overly cautious (since it is the task that actually deletes backup data!), if it encounters something that does not happen during regular operations, it will abort.
