the idea of per user quotas was extreemly attractive, and it _seemed_ like such a good idea when our ZFS manager proposed it... Actually we have per user quotes on the current UFS file system, which is ok for many of the users, but we have those few who say things like - its easier to find stuff in my home directory, I don't want to bother with project directories on other drives. - Just create a few hundred gig of dead space, that way when you need space you have it reserved and can just delete something. Things like NMR or scanning EM microscopes produce large data files... we are just trying to keep the users from harming one another. > -- > --------------- > > Chris Hoogendyk > > - > O__ ---- Systems Administrator > c/ /'_ --- Biology & Geology Departments > (*) \(*) -- 140 Morrill Science Center > ~~~~~~~~~~ - University of Massachusetts, Amherst > > <hoogen...@bio.umass.edu> > > --------------- > > Erd?s 4 > > --- Brian R Cuttler brian.cutt...@wadsworth.org Computer Systems Support (v) 518 486-1697 Wadsworth Center (f) 518 473-6384 NYS Department of Health Help Desk 518 473-0773 IMPORTANT NOTICE: This e-mail and any attachments may contain confidential or sensitive information which is, or may be, legally privileged or otherwise protected by law from further disclosure.
