Hi there. I’m on a fresh Ubuntu install.
$ uname -a
Linux s1.servername.com 6.8.0-138-generic #138-Ubuntu SMP PREEMPT_DYNAMIC Fri Jul 31 22:41:49 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux
I have a problem trying to get disk quotas to work.
On “re-check configuration” under Virtualmin → System Settings, it’s reporting:
[...]
Quotas are not enabled on the filesystem /home which contains home directories under /home and email files under /home. Quota editing has been disabled
[...]
Disks are like so:
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 20G 0 disk
└─sda1 8:1 0 20G 0 part /home/chroot/<NUMBERS>/home/user1
/home/chroot/<NUMBERS>/home/user2
/home
vda 253:0 0 50G 0 disk
├─vda1 253:1 0 49G 0 part /
├─vda14 253:14 0 4M 0 part
├─vda15 253:15 0 106M 0 part /boot/efi
└─vda16 259:0 0 913M 0 part /boot
My /etc/fstab looks like this:
$ cat /etc/fstab
LABEL=ROOT / ext4 discard,commit=30,usrquota,relatime,rw,grpquota,errors=remount-ro,quota 0 1
LABEL=BOOT /boot ext4 defaults 0 2
LABEL=UEFI /boot/efi vfat umask=0077 0 1
/swapfile none swap sw 0 0
LABEL=WEBDATA /home ext4 usrquota,grpquota 0 2
/home/user1 /home/chroot/<NUMBERS>/home/user1 bind defaults,bind 0
/home/user2 /home/chroot/<NUMBERS>/home/user2 bind defaults,bind 0
[...]
Quota appears available for the disk:
$ sudo tune2fs -l /dev/sda1 | grep -i quota
Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent 64bit flex_bg sparse_super large_file huge_file dir_nlink extra_isize quota metadata_csum
User quota inode: 3
Group quota inode: 4
$ sudo dmesg | grep -i 'quota'
[ 0.641116] VFS: Disk quotas dquot_6.6.0
[ 2.528076] EXT4-fs (vda1): mounted filesystem XXX ro with ordered data mode. Quota mode: none.
[ 4.483987] EXT4-fs (vda16): mounted filesystem YYY r/w with ordered data mode. Quota mode: none.
[ 5.145285] EXT4-fs (sda1): mounted filesystem ZZZ r/w with ordered data mode. Quota mode: journalled.
And quotaon reports:
$ sudo quotaon -vug /home
quotaon: using . on /dev/sda1 [/home]: File exists
quotaon: using . on /dev/sda1 [/home]: File exists
which is the same error I get on the Webmin GUI under System → Disk Quotas when clicking “Enable Quotas”.
I’ve seen other posts here suggest installing linux-image-extra-virtual, so I did that, and a server reboot, but still the same error appears when trying to ‘enable’ and on re-check of the config.
What am I doing wrong?
