It is best to create a partition before operation, then format it, and then mount it to the home directory under the root, so that the home directory is independent on a partition.

1) enable disk quota mount option

Execute mount-o remount to take effect again

2) create a quota database

3) enable the database

Quotaon-p to see if the database is enabled

Quotaon enables the database

Quotaoff disables database

4) set quota entry

Edquota username

Edquota-p username1 username2 (copy quota information for user 1 to user 2)
