EDIT June 15, 2022 - I was looking at old logs. This is NOT an issue. Board admins, please delete this entire thread as it is completely invalid.

I manually deleted chunks. Because I did that, I was unable to perform syncs. To fix that, I deleted my Datastore and recreated it. (See https://forum.proxmox.com/threads/sync-fails-with-os-error-2.110703/)

I have not even synced the VM105 backup yet so how could it know a non-existent chunk is required for it?

what do you mean exactly?
the log you posted shows that a chunk from an index in the datastore is non-existant...?
There is not a backup for VM105. So to me, the error message doesn't make any sense.

can you post the output of
cat /etc/proxmox-backup/datastore.cfg
ls -lhR /mnt/datastore/Backups/vm/105
root@alcaeus:~# cat /etc/proxmox-backup/datastore.cfg
datastore: Backups
        path /mnt/datastore/Backups
root@alcaeus:~# ls -lhR /mnt/datastore/Backups/vm/105
ls: cannot access '/mnt/datastore/Backups/vm/105': No such file or directory
I just realized I was looking at the Garbage Collection logs from before I rebuilt the datastore. It can't even do a garbage collection yet because it isn't finishing syncing my VMs. If possible, please delete this thread as it is completely invalid.
