I have my nextcloud data in /media/disk/ncdata.
/media/disk is a btrfs parent, /media/disk/ncdata is a subvolume
When I manually trigger nc-snapshot I get following error:
/media/disk/ncdata is not a BTRFS mountpoint or snapshot
When i list the subvolume using btrfs subvolume list /media/disk I get
ID 10949 gen 83113 top level 5 path ncp-snapshots/hourly_2020-07-11_101701
ID 11072 gen 96219 top level 5 path ncdata
Does someone know what is the problem and how I can get a snapshot?
Not enough Info provided.
Maybe you could run ncp-report and share via pastebin or similar.
I’d also run
sudo df -hT
To verify usage
And run
sudo dmesg
and check /var/log/syslog
to look for btrfs or other errors.
Thanks for answering!
user@nextcloudpi:~$ sudo df -hT
yields

in the syslog there are no btrfs related errors
in dmesg there are many errors like this:
[2191008.902103] BTRFS info (device dm-0): Snapshot src from another FS [2191880.138319] BTRFS info (device dm-0): Snapshot src from another FS [2192800.837723] BTRFS info (device dm-0): Snapshot src from another FS
ncp-report yields https://pastebin.com/1pdJetcX
Do you see something?
