Subject: [newb] btrfs send problem

Message-ID: <lb8ue0$hic$1@ger.gmane.org> (raw)

I hope this is an appropriate place to ask user questions.

I'm trying out snapshot and replication.  I have

/dev/sda3 on / type btrfs (rw,relatime,ssd,space_cache)
/dev/sda3 on /home type btrfs (rw,relatime,ssd,space_cache)

create a subvolume for snapshots:

#btrfs sub create /.snapshots
Create subvolume '//.snapshots'

[root@nbecker1 nbecker]# btrfs subvolume list /
ID 256 gen 563396 top level 5 path home
ID 258 gen 563396 top level 5 path root
ID 372 gen 563396 top level 258 path .snapshots

[root@nbecker1 nbecker]# btrfs sub snapshot -r /home /.snapshots
Create a readonly snapshot of '/home' in '/.snapshots/home'

[root@nbecker1 nbecker]# btrfs subvolume list /
ID 256 gen 563398 top level 5 path home
ID 258 gen 563398 top level 5 path root
ID 372 gen 563398 top level 258 path .snapshots
ID 373 gen 563398 top level 258 path .snapshots/home

[root@nbecker1 nbecker]# btrfs send /.snapshots/home > /dev/null
At subvol /.snapshots/home
ERROR: open root/.snapshots/home failed. No such file or directory
