Subject: finding root filesystem of a subvolume?
Date: Tue, 22 Aug 2017 14:23:50 +0200	[thread overview]
Message-ID: <20170822122350.GA14804@rus.uni-stuttgart.de> (raw)

How do I find the root filesystem of a subvolume?
Example:

root@fex:~# df -T 
Filesystem     Type  1K-blocks      Used Available Use% Mounted on
-              -    1073740800 104244552 967773976  10% /local/.backup/home

root@fex:~# btrfs subvolume show /local/.backup/home
/local/.backup/home
        Name:                   home
        uuid:                   f86a2db0-6a82-124f-9a71-1cd4c20fd6fb
        Parent uuid:            ba4d388f-44bf-7b46-b2b8-00e2a9a87181
        Creation time:          2017-08-10 22:19:15
        Object ID:              383
        Generation (Gen):       148
        Gen at creation:        148
        Parent:                 5
        Top Level:              5
        Flags:                  readonly
        Snapshot(s):


I know, the root filesystem is /local, but who can I show it by command?
