Quick and dirty notes for getting XFS project quotas running: I’m working on making storage areas for various capstone design class groups, vehicle teams, etc. I’d like to ensure that they don’t take an excessive amount of storage, too. These instructions are slightly different than what I’d found elsewhere, and I’m hoping to have someone confirm that what I’m doing is correct and update the appropriate man pages accordingly.
So assuming we have a project for ME4444, group 3 (I already had projects defined for groups 1 and 2 from earlier tests):
# grep /home /etc/fstab
/dev/md1000/home /home xfs defaults,usrquota,prjquota 0 1
# echo "me4444-03:/home/projects/me4444-03" >> /etc/projects
# echo "me4444-03:3" >> /etc/projid
# mkdir /home/projects/me4444-03
# xfs_quota -x -c "project -s me4444-03"
Setting up project me4444-03 (path /home/projects/me4444-03)...
Processed 1 /etc/projects paths for project me4444-03
# xfs_quota -x -c "limit -p bsoft=5g bhard=10g me4444-03"
# xfs_quota -x -c "report -p"
Project quota on /home (/dev/md1000/home)

---------- --------------------------------------------------
me4444-01 0 0 1048576 00 [--------]
me4444-02 0 5242880 10485760 00 [--------]
me4444-03 0 5242880 10485760 00 [--------]
Now group 3 has a 5 GB “soft” quota, can exceed that for up to 7 days at a time, but can never exceed their 10 GB “hard” quota. All that’s left is setting up directory permissions and Samba configuration so that the authorized users can store things there.
