[lustre-discuss] lfs quota reports file usage but no files found via lfs find

[Rasool Almasikoupaei]

Hi all,

We are seeing a discrepancy between what /lfs quota/ reports and what we 
can locate using /lfs find/ or the standard find command.
For example:

/lfs quota -uh username /mnt/lustre/

Disk quotas for usr username (uid 101559):
      Filesystem    used   quota   limit   grace   files quota   limit   
grace
    /mnt/lustre/  970.1M      0k      0k       -      22 0       0       -

uid 101559 is using the default block quota setting
uid 101559 is using the default file quota setting/


However, neither /lfs find -user username/ nor the standard /find/ 
command can locate these 22 files.
Running /lfsck/ has no effect and produces the same result.

We have observed this behavior on Lustre 2.15.6 and continue to see it 
on 2.15.7 and 2.15.8.
The example user’s access was revoked before any file search was performed.

Does anyone have an idea how to locate or clean up these ghosted files, 
or how to fix the quota reporting discrepancy?


Best,
Rasool
