Subject: generic name for volume and subvolume root?
Date: Sat, 9 Sep 2017 10:35:51 +0200	[thread overview]
Message-ID: <20170909083551.GC22060@rus.uni-stuttgart.de> (raw)

As I am writing some documentation abount creating snapshots:
Is there a generic name for both volume and subvolume root?

Example:

root@fex:~# btrfs subvol show /mnt
ERROR: not a subvolume: /mnt

root@fex:~# btrfs subvol show /mnt/test
/mnt/test is toplevel subvolume

root@fex:~# btrfs subvol show /mnt/test/data
/mnt/test/data
        Name:                   data
        UUID:                   b32a5949-dfd6-ef45-8616-34ae4cdf6fb8
(...)

root@fex:~# btrfs subvol show /mnt/test/data/sw
ERROR: not a subvolume: /mnt/test/data/sw


I can create snapshots of /mnt/test and /mnt/test/data, but not of /mnt
and /mnt/test/data/sw

Is there a simple name for directories I can snapshot?
