Hmmm...the time required is more dependent on inodes
than on size of data / size of files, right ?

My 9 TB dataset uses about 36 million inodes.

Any comments on that number ?  Large ?  Pedestrian ? 
Typical ?

I am hoping that that could be fsck'd (modern hitachi
SATA drives, raid-6, 3ware) in 48 hours ... or am I
way off ?

Ok, but all of the CLI tools (edquota, repquota,
quota, quotacheck, quotaon) are all known-good for
"bigdisk" ?

And there is no known "quotas just don't work with
bigdisk" problems ?

I was hoping someone out there was running quotas with
6.1-RELEASE on a >2TB filesystem and could report favorably...
