[lustre-discuss] lfsck repair quota

[Martin Hecht]

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

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:

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.)
