issue in user Quota creation

Question

I am trying to create a users quota in RHEL-7 with xfs file system. But I am not able do it. The procedure that I followed is as below :-

1) edit /etc/fstab/

/dev/mapper/rhel-root / xfs defaults,usrquota,grpquota 0 0 UUID=58c22d1f-85ca-4fb9-8d40-4cfbaaf0d7ca /boot xfs defaults 0 0

2) Then mount -vo remount /

mount: /dev/mapper/rhel-root mounted on /.

3) reboot too

and then checked if quota feature is enabled or not , and fount it is not enabled.

 # mount | grep 'root'

/dev/mapper/rhel-root on / type xfs (rw,relatime,seclabel,attr2,inode64,noquota)

Can you tell me its cause and how to resolve it.

Answer 1

xfs file system manages quota differently from other fs. And you need to activate flag rootflags=quota in the /etc/default/grub.

In detail: edit /etc/default/grub, adding or editing the value

GRUB_CMDLINE_LINUX="rootflags=quota"

run update-grub and performs reboot. Quota should be activated. This process may be slightly different depending on the distro.
