[lustre-discuss] recovery MDT ".." directory entries (LU-5626)

[Chris Hunter]

We have a lustre 1.8 filesystem that was upgraded to lustre 2.x and 
"dirdata" feature was enabled. We encountered LU-5626/LU-2638 issue with 
".." directory entries. Are there established recovery steps for this 
issue ?

If I run fsck, the directory entries will be moved into lost+found.
I assume the next step is to run the ll_recover_lost_found_objs tool ?

Can you share any advice/experience about recovery ?

thanks,
