Yes, I have used gmane blog. Good to know it is not down anymore.
Back on topic. Even after updating to the latest version, btrfsck
or any of its options including --repair still do not work. Does anyone
know what "Assertion `rec->is_root` failed" means? Is it worth trying to
compile my own version of btrfsck without this assertion?
With or without --repair option, it looks like this assertion stops
btrfsck very early, preventing btrfsck from checking the filesystem or
attempting to repair it.
