XO Remote mount.nfs: access denied by server while mounting
-
I setup another VM as someone suggested and the NFS share mounted and worked. So there is something I am not understanding about docker permissions / requirements.
In the end, following a permissions reset and forcing the NFS share to squash and use my user/group ID I think I have progress. I can see it is writing to the NFS share.
Then I got : EEXIST: file already exists, open '/run/xo-server/mounts/6299d107-2aa2-41bf-bfd7-2f487ff5422f/xo-vm-backups/801e2b10-5c7d-b7af-ad5e-fbcc83e47d5b/.20220930T221548Z.xva'
A quick google led me to this being related to nfs 3. I switched to NFS 4 then I got path not found.
Not sure why, but I tried removing "export" from the path and it worked.
It does appear now to be running a backup job .... fingers crossed.
What a mine field!
Thanks for all the pointers.

@daninmanchester Yes, a mine field is about right. Super good ou have made so much progress!

Now you understand why we sell/distribute XO in a virtual appliance we can test

@olivierlambert I think the intricacies of NFS, my seemingly borked NFS permissions were likely the real issue. I rarely have real problems with XO. I tried proxmox but didn't get on with it so switched back.
I'm just a home / homelab user, but always impressed with the community around XCP-NG too and have learnt a huge amount from Lawrence Systems.
Anyway this morning I have a successful backup completed :
Thanks again.

Great news! Enjoy

@daninmanchester Thanks so much - this is the exact same problem I had, which was further complicated by running XO in Docker running on the OMV host exporting the NFS shares.
So basically you just built a small XO VM instead of running it in Docker? I had originally been thinking of making a small VM to run XO in a container there - just because Docker containers are super easy to keep updated and I could run some other orchestration-y stuff there too, like Rancher - but if you're saying that's a non-starter I'll just bite the bullet and build a tiny VM dedicated to XO and be very grateful to you for having saved me a lot of frustration.
