EPERM on accessing NFS Share on Synology NAS

[PPee]

When adding a datastore in PBS I keep getting the EPERM message.
Setup:
I configured a NFS share on Synology: /volume1/ProxmoxBS
In the settings I gave access to the ip of my PBS with map all users to admin
The PBS is in a VM on a pve (one of the pve's in a cluster of three)
In the vm I mounted /volume1/ProxmoxBS as an nfs -fstab line added: 192.168.1.xxx:/volume1/ProxmoxBS /mnt/SPlusPBS nfs rw,sync,no_root_squash 0 0
The mount is working fine if I check with df -h - proper size
Then when I add the datastore to PBS it is giving EPERM

What did I miss?

Can you share us your NFS configuration from your Synology?

What is your error message on the journallog when you try to add the datastore? Have a look at this Thread [1]. Perhaps you will find a solution there.

Have you set this already? https://forum.proxmox.com/threads/c...erm-operation-not-permitted.97521/post-602676

mmm I think I solved it. I created a user with the same UID (34 in my case) on the synology NAS and gave it permission for reading and writing in the shared folder with the ssh command: sudo synouser --add BackupUser <pw> "Backup User" 0 "" "User"
NFSpermissions should be set to ¨no mapping¨
