Restore from nfs fail n

Nextcloud AIO is currently running on a Raspberry Pi. The data directory is on an NFS share. Now I want to switch to running Nextcloud AIO in Docker on TrueNAS Scale. Creating a backup worked without any problems, but the restore always crashes at the last percent. I can’t really tell anything from the logs, except that the NFS restore is causing permission issues.

@daschmidt94

i have no answer, only new questions :wink:

That part is about sql dump and it looks like this is the only ‘Failed’ one, other are more ‘Not supported’ setting of extended attributes on files.

is there anything remaining in `nextcloud_aio_volumes’ currently ? Just to see if sql is there and if it looks like a sql one.
Understanding state of backup file would help, where is it how big is it… can it be checked for corruption before extraction …

thanks for your repley

I somehow managed to get the instance started again today, despite the restore aborting. All the data looks like it’s there. A subsequent backup also worked perfectly. I don’t want to spend too much time clicking around now that it’s running.
Is there any way I can check if there are any problems with the database?

If your instance is running this is already a good hint that database is ok, a corrupted database often prevent nextcloud to work properly.
Check all users are there and that rights are the same.

hope that the restore is also working if i need it.
I’m afraid to test it again…

Do you know what the best setting for the zfs dataset are?

@daschmidt94 i don’t know how to setup zfs sorry. ‘zfs’ not ‘nfs’ ?

in the past I used an nfs store for my nextcloud datadir.
Now I moved it on truenas scale on a ZFS Dataset.
