[pbs-devel] [PATCH proxmox-backup v4 14/14] chunk store: never fail when trying to remove missing chunk file

[Christian Ebner]

Although this is an unexpected case, never fail if the chunk store
marker is not there during removal from cache in phase 2 of garbage
collection for datastores with s3 backend (that codepath needs no
further adaption). The chunk file might be missing for other reasons,
e.g. after manual intervention in offline maintenance mode.
