possible bug in ext3/4 recovery

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

 



Hi list,

While inspecting some strange "corruptions" in Lustre servers i found situation when we try to check disk descriptors before loading/recovering a journal.
but with descriptors checksum enabled we may have a situation when we have update a checksum but don't have a real update for a descriptors because they stay in different blocks on disk. From other view both updates exist in journal and may be replayed to make in consistence.

What about moving a ext4_check_descriptors after 'no_journal' label to be sure we have check in consistence data?
