Is development effort being devoted to Btrfsck at the moment? I know it was long delayed and still not considered complete when released, but that was quite a while ago.
As long as there are filesystems which can't be repaired online they need to maintain such tools. Currently there are some errors which are almost theoretically impossible to repair online (EG certain types of log corruption that might make it impossible to mount the filesystem) and some errors which are practically impossible due to the kernel being buggy (my filesystem causes a kernel oops on mount).
I also know that online fsck is among their longer-term project objectives, since a full off-line scan and repair of today's high-capacity drives is considered unacceptably time-consuming in some environments.
The aim is to have routine errors fixed online, the old thing of having a long fsck every certain number of days or certain number of boots has to go. But there will always be situations where a filesystem can't be fixed online. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
