[Lustre-discuss] broken quotas

Hi John,

My understanding is if your quota files are broken, and lfs quotacheck 
isn't working, you can take a downtime and remount all the devices as 
ldiskfs and delete the lquota files, which should look something like:
-rw-r--r-- 1 root root  6144 Jul 20 09:05 lquota_v2.group
-rw-r--r-- 1 root root  6144 Jul 20 09:05 lquota_v2.user

Then you shoule be able to run lfs quotacheck again.

Of course, mounting as ldiskfs is dangerous, but I think the risk of 
this operation is not so high. I would make sure any crucial data is 
backed up.

During that work, we attempted to enable quotas on 2 file systems (generated the initial file, etc).  Once we realized our mistake, we back-rev'd to the 1.8.x train and most everything went back smoothly except for quotas. Now whenever we attempt any quota related commands, we get ioctl errors.  For example:
> [root at lrc-xfer ~]# lfs quota -u jwhite /clusterfs/vulcan/pscratch
