Hi there,

I have a system on which btrfsck gives the following output... I don't
understand the meaning of the reported errors, so any clue would be
appreciated. Is this something I should worry about, or not ?

Would I be advised to try "--repair" ? (Last time I tried this one, it
completely b0rked a filesystem, beyond repair, and my wife would kill me
ifever I trash this one, for that's her machine, so please help ! ;-))
