Sorry, I pasted the wrong thing.
ABORT: btrfs send -p /mnt/btrfs_pool1/Video_ro.20180220_21:03:41
Video_ro.20180308_07:50:06 | btrfs receive /mnt/btrfs_bigbackup/DS1//. failed
At subvol Video_ro.20180308_07:50:06
At snapshot Video_ro.20180308_07:50:06
ERROR: cannot find parent subvolume
Same problem basically, just copied the wrong attempt, sorry about that.
Do I need to make sure of more than
DS1/Video_ro.20180220_21:03:41
Received UUID: 2afc7a5e-107f-d54b-8929-197b80b70828
be equal to
Name: Video_ro.20180220_21:03:41
UUID: 2afc7a5e-107f-d54b-8929-197b80b70828
Thanks,
