Eric, Thanks for your comments and help - your posts on this list are much appreciated.

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 ? > > But I do absolutely need to run quotas (both user > and > > group) on this 9 GB array.

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... __________________________________________________ Do You Yahoo!? Tired of spam?
