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
