Hi there, I noticed my syslog is filling up with tons of: btrfs: free space inode generation (0) did not match free space cache generation (25326) ...any clue ?

Did you have a unclean unmount at some point? Do you have a particularly full file system? I recently increased the size of the free space cache, so if you are not on a kernel with that patch you are more likely to run out of space while writing out free space cache and run into this problem.

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 <swami@petaramesh.org> http://petaramesh.org PGP 9076E32E Ne cherchez pas : Je ne suis pas sur Facebook. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
