Dear Martin.
I tried to run the e2fsck in the mdt three years ago and the logs shows
a lot of this kind of messages:
Unattached inode 26977505
Connect to /lost+found? yes
Inode 26977505 ref count is 2, should be 1. Fix? yes
In fact I think that the e2fsc ran so slow due that all the mdt inodes
were corrected.
Regards.

Are there a lot of inodes moved to lost+found by the fsck, which contribute to
the occupied quota now?

Betreff: Re: [lustre-discuss] lfsck repair quota
Thank you Rick.
I followed these steps for the ldiskfs OSTs and MDT, but the quotes for all
users is more corrupted than before.
I tried to run e2fsck in ldiskfs OSTs MDT, but the problem was the MDT e2fsck
ran very slow ( 10 inodes per second for more than 100 million inodes).
According to the lustre wiki I though that the lfsck could repair corrupted
quotes:

Could anyone confirm me that the correct way to repair wrong quotes in a
ldiskfs mdt is lctl lfsck_start -t layout -A?
As far as I know, lfsck doesn’t repair quota info. It only fixes internal
consistency within Lustre.
Whenever I have had to repair quotas, I just follow the procedure you did (unmount
everything, run “tune2fs -O ^quota <dev>”, run “tune2fs -O quota <dev>”, and
then remount). But all my systems used ldiskfs, so I don’t know if the ZFS OSTs introduce
any sort of complication. (Actually, I am not even sure if/how you can regenerate quota
info for ZFS.)
