Subject: Can a snapshot become a parent subvolume when its parent is deleted?
Date: Wed, 14 May 2014 06:50:57 -0700	[thread overview]
Message-ID: <20140514135057.GA12849@merlins.org> (raw)

So, I had btrfs_pool1 that was trashed/lost as discussed here recently.

I did btrfs send btrfs_pool2/root_ro.date | btrfs receive /mnt/btrfs_pool1

Then btrfs subvolume snapshot root_ro.date root

Now, after I delete root_ro.date on btrfs_pool1, shouldn't root become a
parent subvolume?

Right now, I have:
legolas:/mnt/btrfs_pool1# btrfs subvolume list -q . 
ID 390 gen 5954 top level 5 parent_uuid faea7df8-d51a-6b4b-994b-887d55267cce path root
legolas:/mnt/btrfs_pool1# btrfs subvolume list  -u .  |grep faea7df8-d51a-6b4b-994b-887d55267cce
legolas:/mnt/btrfs_pool1#

Is it possible not to have a parent?

If so, shouldn't you become a parent at that time?

Thanks,
Marc
