[SOLVED] Question about permissions on the datastore backing path

[Ovidiu]

test install of pbs here. going straight to add new datastore, give it a name and as path I enter /storage/backups/pbs

as a result pbs creates the pbs folder as /storage/backups already exists and seems to make a chown -R backup:backup /storage/backups/pbs and apparently sets 755 as permissions.

a few seconds later, pbs can no longer access the .chinks folder

Bad Request (400)
unable to open chunk store 'pbs-local-enc' at "/storage/backups/pbs/.chunks" - Permission denied (os error 13)

 ls -al pbs/
total 16482
drwxr-xr-x     3 backup backup     4 Nov 19 13:39 .
drwxr-xr-x     4 backup backup     4 Nov 19 13:39 ..

-rw-r--r--     1 backup backup     0 Nov 19 13:39 .lock

ls -al /storage/backups/

drwxr-xr-x  4 backup backup  4 Nov 19 13:39 .
drwxrw---- 11 root   root   11 Aug 27 11:06 ..
drwxr-xr-x  3 backup backup  4 Nov 19 13:39 pbs

ls -al /storage/
total 781
drwxrw----   11 root   root     11 Aug 27 11:06 .
drwxr-xr-x   19 root   root     25 Aug 10 06:44 ..
drwxr-xr-x    4 backup backup    4 Nov 19 13:39 backups

how do I manually fix this?

p.s. for now, pbs is installed straight onto my single PVE instance as shown here: https://pbs.proxmox.com/docs/installation.html#install-proxmox-backup-server-on-proxmox-ve

we create the datastore as root and chown it to backup:backup but i see in your path that /storage/ is 760 and belongs to root:root, so the backup user cannot access anything below it

the backup user needs at least x rights on the complete path

thanks, that hint solved it.
