How user and group quotas work with qtrees
Tree quotas limit the overall size of the qtree. To prevent individual users or groups from consuming the entire qtree, you specify a user or group quota for that qtree.
Suppose you have the following quotas file:
#Quota target type disk files thold sdisk sfile #----------- ---- ---- ----- ----- ----- ----- * user@/vol/vol1 50M - 45M jsmith user@/vol/vol1 80M - 75M
It comes to your attention that a certain user, kjones, is taking up too much space in a critical qtree, qt1, which resides in vol2. You can restrict this user’s space by adding the following line to the quotas file:
kjones user@/vol/vol2/qt1 20M - 15M
