Subject: btrfs snapshot sizes
Date: Wed, 7 May 2014 04:19:49 -0700 [thread overview]
Message-ID: <20140507111949.GT10159@merlins.org> (raw)
So have others found a good way to have an idea about how much space is
taken by each snapshot?
I've tried quota trees, but I'm not sure how to read the output, or if it's
correct (including the negative numbers some have mentioned). Are there
other options?
I think the main problem is that the shared data field is not working,
making it harder to know which blocks are only used in a given snapshot.
