Folks

I'm trying to use xfs_quota to keep track of disk space usage for my users.

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.

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. # /dev/mapper/cl_ape-root /                       xfs     defaults        0 0 UUID=d5a206d6-7ea1-42b7-8f52-071e98d09f98 /boot ext4    defaults        1 2 /dev/mapper/cl_ape-swap swap                    swap    defaults        0 0 [root@ape ~]#

Yet, when I look at the current mounts of xfs file systems:

[root@ape ~]# mount | grep xfs /dev/mapper/cl_ape-root on / type xfs (rw,relatime,attr2,inode64,noquota) /dev/mapper/vg_abcde-lv01 on /home1 type xfs (rw,relatime,attr2,inode64,noquota) [root@ape ~]#

the LV of the second disk shows up.

lsblk NAME            MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT sda               8:0    0   25G  0 disk +-sda1            8:1    0    1G  0 part /boot +-sda2            8:2    0   24G  0 part   +-cl_ape-root 253:0    0 21.5G  0 lvm  /   +-cl_ape-swap 253:1    0  2.5G  0 lvm  [SWAP] sdb               8:16   0  5.2T  0 disk +-vg_abcde-lv01 253:2    0  5.2T  0 lvm  /home1 sr0              11:0    1  597M  0 rom [root@ape ~]#

How do I enable quotas on a file system that is being mounted but not in fstab?  I suspect systemd has a role here, but I can't find any evidence.
