So you're saying the directory entry was missing? Can you tell me how big
the directory was? Number of files? Approximate directory size when you
consider file names? When you fsck'd were inodes recovered and linked
into lost and found? What was the actual path?
I'm trying to wrap my head around how this would be possible and where the
error could be and whether it could be caused by SUJ. The number of
interactions with disk writes are minimal. Corruption if it occurs would
most likely be caused by a bad journal recovery.
Thanks,
Jeff
