[Lustre-discuss] lfsck_start

[Andrus, Brian Contractor]

All,

I am running the latest lustre rpms (lustre-2.6.0-2.6.32_431.20.3.el6_lustre.x86_64.x86_64).
One of our OSTs is throwing errors whenever e2fsck is run:

[ERROR] quotaio_tree.c:590:check_reference:: Illegal reference (2767 >= 54) in user quota file. Quota file is probably corrupted.
Please run e2fsck (8) to fix it.

We are not running quotas on the filesystem.

I thought it may be a good idea to run lfsck on the system, but things have changed and now I get a message to use lfsck_start.
Now, I am having great difficulty finding documentation on running it although I do see quite a few code bits and bugs about it.
All I find is the standard help message put in the documentation, but nothing that goes into any detail about any of the options. It also seems no matter what options I try, I get:

Fail to start LFSCK: Operation not supported

1)  What could be causing such an error on an OST
2) Are there any detailed descriptions/examples of running lfsck_start for the 2.6 code?
