CentOS 8 And Xfs_quota
Folks
I’m trying to use xfs_quota to keep track of disk space usage for my users. The documentation states that I should specify “uquota” as an option on the mount data in /etc/fstab. Yet, I cannot find the entry in fstab that corresponds to the Logical Volume that ends up being mounted on /home1.
The system in question was installed on a single disk system. Later, after install, I added a second disk, created a Logical Volume on it, and mounted it as /home1, where all the user data gets stored. It holds an xfs file system.
Upon examining /etc/fstab, there’s no evidence of the second disk, yet it does get mounted:
[root@ape ~]# cat /etc/fstab
#
# /etc/fstab
# Created by anaconda on Fri May 1 21:05:38 2020
#
# Accessible filesystems, by reference, are maintained under ‘/dev/disk/’.
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info.

# After editing this file, run ‘systemctl daemon-reload’ to update systemd
# units generated from this file.

One thought on - CentOS 8 And Xfs_quota
Here is what I have:
/etc/fstab
—-
LABEL=/home /home xfs defaults,usrquota 1 2
—-
once usrquota is in fstab, unmount and mount again /home; then you will see
# mount | grep home
/dev/sdb1 on /home type xfs (rw,usrquota)
(or similar)
To set quotas once for all users (and any users added in a future):
xfs_quota -x -c “limit bsoft=9g bhard=10g -d” /home
or make some individual quota different than already set for everyone:
xfs_quota -x -c “limit bsoft=7g bhard=8g valeri” /home
Here you should be done. In fact, you will not see quota status, occupancies of given user until the user writes something after the quotas had been set.
I hope, this helps.
