Hi
Since the time I issued, as root:
# btrfs subvolume set-default 1112 /mnt2/cameras
and rebooted, I found the /mnt2/data (the whole BTRFS volume) is mounted pointing at subvolid=1112.
Actually, all shares (=subvolumes) were mounted with this vol id setting.When I issued:
# btrfs subvolume list /mnt2/cameras
I was later able to find the right snapshot to point at for every share.What I’m not able to find now is the original subvolid to point at to mount the whole BTRFS filesystem in /mnt2/data and where this value is stored, finding the /etc/fstab doesn’t deal with its mounting (UUID not present).
If I try to mount the subvolid=5, then the response is it is already mounted as /mnt2/rockstor_rockstor.
Notice this mount uses a different device, specifically /dev/sda3.
/mnt2/data mounts the other /dev/sdd device.How to find the right subvolid to mount?
