Subject: chattr +C vs. btrfs subvolume snapshot
Date: Tue, 8 Jan 2013 00:37:11 +0000 [thread overview]
Message-ID: <1TsN9p-000FDf-SX@internal.tormail.org> (raw)
What happens if you set an individual file inside a subvolume as nocow
(chattr +C) and then take a snapshot of that subvolume and modify the
file in both?
Will btrfs now ignore the nocow attribute completely or will it do "as
few copies as possible"? (I'd love to know if it's possible to visualize
the fragmentation of a single file.)
