Only, I have several Linux distros installed on the same BTRFS - in different subvols - so I sometimes mount it with a 3.5.x kernel, and more rarely - but sometimes - with a 3.2.x... => Also I have to mention that I have lost a complete BTRFS FS, that was a /boot with snapshots. At some point it started to fail mounting, the kernel complaining that some trees (corresponding to removed snapshots as far as I could tell) were b0rked, and btrfsck couldn't help... So I lost the FS - and lost quite a bit of confidence into BTRFS the same day... :-\ -- Swâmi Petaramesh http://petaramesh.org PGP 9076E32E Ne cherchez pas : Je ne suis pas sur Facebook.
