trouble mounting btrfs filesystem....

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

Early this morning there was a power glitch that affected our system.

The second enclosure went offline but the file system stayed up for a
bit before rebooting and recovering the 2 missing arrays sdb1 and
sdc1.

When mounting we get....

    Aug 12 14:52:43 localhost kernel: [ 8536.649270] BTRFS info (device sda1): has skinny extents
    Aug 12 14:54:52 localhost kernel: [ 8665.900321] BTRFS error (device sda1): parent transid verify failed on 177443463479296 wanted 2159304 found 2159295

We are here...
