Hi All,

It seems my btrfs file space cache is corrupt; I had to run clear the log
through a kernel problem.

I've seen messages that the cache is rebuilt automatically, but this doesn't
seem to be true as the messages that the free space is what is expected keep
coming.

I'm running kernel 3.8.2 (Siduction) on Debian testing.


I believe you may try clear_cache mount option
https://btrfs.wiki.kernel.org/index.php/Mount_options



As a subsidiary question, please, should the <pass> value in fstab be zero or
non-zero?


It should be zero. But since fsck.btrfs is non-existent, it does not
really matter I guess.

    Eh? We've had a functional btrfsck for nearly a year.


Right. But it is not something that you run on boot, is it. That is why I mentioned fsck.btrfs



    Hugo.
