When rebuilding PBS, the datastore permissions may need to be repaired.
1. Use the chmod Command to make the Root DataStore /pve-backups/ Directory in /mnt/ have the Same Permissions Listed in the Code Snippet.
chmod 755 /mnt/pve-backups/
2. Use the chmod Command to make the DataStore SubDirectories of /mnt/pve-backups/ have the Same Permissions listed in the Code Snippet.
chmod 644 /mnt/pve-backups/.lock
chmod -R 750 /mnt/pve-backups/.chunks
NOTE: The Chunk Directory has a SubDirectory so you will have to use chmod -R for Recursive. This Applies the Permissions to the .chunck Directory and SubDirectories within .chunk.
