Quotas

A quota limits the amount of disk space and the number of files that a particular user or group can consume.

A quota can also restrict the total space and files used in a qtree, or the usage of users and groups within a qtree.

A request that would cause a user or group to exceed an applicable quota fails with a “disk quota exceeded” error

A quotas can assign for USER, GROUP, & QTREE

Steps to ASSIGN quotas

1. Make the below entry in /etc/quotas

  /vol/vol1/qtree1             tree     300mb

   /vol/vol1/qtree1 - give the QTREE full path

  tree - TYPE [ if we are assignining quotas for USER/GROUP mention as user/group]

  300mb – size  [Qtree SIZE]

2. quota on -w vol1    [ it will scan the /etc/quotas file and it will ON the quota]

3. quota off vol1    [it will OFF the quota]
