Subject: Receive on same subvolume
Date: Wed, 29 Jan 2014 13:26:53 -0800	[thread overview]
Message-ID: <52E9721D.6000908@matthewlai.ca> (raw)

Hello,

Is this supposed to work? (/data is the root volume, /data/a is a subvolume)

btrfs subvolume snapshot /data/a /data/b
# make some changes in b
btrfs send -p /data/a /data/b > delta
btrfs receive /data/a < delta

I'm getting "ERROR: could not find parent subvolume" on receive.

What I'm trying to do is to back up using send/receive, but I don't have 
50% free space, and (please correct me if I'm wrong) since receive 
doesn't do deduplication, I want to use snapshot to do the initial 
bootstrapping, instead of send/receive without a parent.

Thanks!
Matthew
