Subject: How to clone btrfs partition?
Date: Sun, 17 Feb 2013 00:14:30 +0100	[thread overview]
Message-ID: <512012D6.7010403@statystyka.net> (raw)

Welcome,

I need to clone btrfs partition. Not a single snapshot, but the whole 
lot of snapshots.

I thought that send & receive can help me. Can it? When I try to use

   btrfs send /mnt/btrfs-root >/dev/null
I get "ERROR: /mnt/adama-docs is not read-only.", and I was explained that I need to use snaphot (created with the "-r" switch).

So does it mean that I need to make a recursive search for each read&write subvolume on the file system in order to make a read-only snapshot, so I can clone the whole partition? Or is there a more simple approach?
