Now I'm not one to accuse someone of being too cautious, but you're worried about having less than 1 GB on a 4.5 GB drive? That's 22.2% of your total space. > 1) With a 4.5GB hard drive, and say 150 users, what would happen if the > total amount of quotas set exceeds the size of the hard drive, even if > there is still free space available on the drive? Nothing. > Does it matter?

The -i option shows the number of inodes that are free... Is that really a concern? Those numbers seem reasonable. If a huge portion of your users decided to fill up to the hard limit at once, you could potentially fill the disk. However, only you can weigh the likelyhood of that occuring versus the added advantage the users get by having a little more breathing space between the hard and soft limit. > 2) Should the sum of all the block limits used by users in repquota -a > (shows 2887728) be equal to the number of blocks used (1K blocks) in a df > -i output (shows 2871052)? What would the difference be? Do the system users (root, bin mainly) have quotas? Do users without quotas show in the totals? (I'm really asking, I dunno.) That's about 16 MB. Is there one (or a few) normal user who got left off a list somewhere? > TIA for any assistance. Glad to help. I'd like to hear anyone's experience with quotas. They are marked as broken in 2.2.x, but I'm thinking of installing them any way on a mailserver to keeps some problems I've had from reoccuring. -- Crist J.
