soft quotas

There may be some confusion as to *exactly* what you mean by soft quotas, and how they work. Someone once asked me that the next time someone

mentioned

this, to ask them to PLEASE explain what you expect the soft quotas to do, how they work, and how they currently work on your other (say, Sun) machines.

My understanding of soft quotas is that, say, you give a user a soft quota of 20 MB and a hard quota of 50 MB.

If they are over their soft quota, then when they log in, and every time they try to write out a file, it succeeds, but also gives them a message saying, "You're over quota. Fix it."

If they're over their hard quota, it just doesn't succeed.

Does anyone else have a different impression?

And how are soft quotas implemented over NFS?
