after adding a new datastore ,
Code:
proxmox-backup-manager datastore create  fbc-long-term-backups2 /fbc-backups/fbc-long-term-backups2

when I click on it in pbs web page :
Code:
Bad Request (400)
unable to open chunk store 'fbc-long-term-backups' at "/fbc-backups/fbc-long-term-backups/.chunks" - Permission denied (os error 13)

the file permissions look OK:
Code:
ls -ld  /fbc-backups/*/.chunks
drwxr-x--- 65538 backup backup 65538 Jul 18 16:08 /fbc-backups/fbc-long-term-backups2/.chunks/
drwxr-x--- 65538 backup backup 65538 Jul 13 07:52 /fbc-backups/fbc-long-term-backups/.chunks/
drwxr-x--- 65538 backup backup 65538 Jul 11 08:48 /fbc-backups/store1/.chunks/

I tried adding the pb-user to have permissions..
 
those seem to be two different issues:
- the first might be a cached ACL on the server side
- the second looks like a missing ticket refresh for long running syncs

does the first still happen if you restart proxmox-backup-proxy and proxmox-backup? is the second reproducible?
 
I have this same issue. This is the perms I have before I mount


drwxr-xr-x 4 root root 4096 Feb 29 16:01 .
drwxr-xr-x 18 root root 4096 Feb 29 10:37 ..
drwxr-xr-x 3 root root 4096 Feb 29 15:49 datastore
drwxr-xr-x 2 root root 4096 Feb 29 16:03 s3-bucket

When I manually mount this is the perms. This is my mount command: "s3fs mpproxmox-backup /mnt/s3-bucket/ -o passwd_file=/etc/passwd-s3fs -o url=https://s3.amazonaws.com"


drwxr-xr-x 4 root root 4096 Feb 29 16:01 .
drwxr-xr-x 18 root root 4096 Feb 29 10:37 ..
drwxr-xr-x 3 root root 4096 Feb 29 15:49 datastore
drwx------ 1 root root 0 Dec 31 1969 s3-bucket
 
that's likely fuse's "allow_other" setting, but using a fuse-backed datastore is probably not a good idea for other reasons anyway..
 
This is what I found worked for me.

s3fs#mpproxmox-backup /mnt/s3-bucket/ fuse _netdev,allow_other -o passwd_file=/etc/passwd-s3fs -o url=https://s3.amazonaws.com -o umask=0022 -o mp_umask=0022

What issues are there with Fuse?
 
it might not implement all the operations PBS requires, and it is probably not very high performance either ;)
