Btrfs devel - Mar 2012 - btrfsck integration with userlevel API for fsck

Are there plans to integrate btrfsck with the userlevel API for fsck?
AFAIK, it currently does not work as such (i.e. `shutdown -rF now`
does not trigger a check on the next boot).  What is the recommended
method to check a btrfs root filesystem?  Live media?

There isn''t even a stable, working, fixing btrfsck yet :)

Currently? None. Set the last part of root line in fstab to "0" to
disable fsck.
Newer kernels should be smart enough to recover from unclean shutdown
automatically, kinda like what zfs does, or what ext3/4 does with its
journal replay.

Yes, there is. Chris merged the btrfsck changes into the btrfs-progs master in
git a few days ago and we shipped it with the Oracle Linux UEK2 update as well.

Cheers,

Ah, OK. I must''ve missed the announcement. Thanks for the update.

Now if only UEK2 fully supports LXC as well instead of tech preview ... :D
