Mounting /home directory on its own drive breaks quotas (?)

[Ron_E_James_D.O]

I had some advice in here on moving my /home directory to a drive of its own:

https://forum.virtualmin.com/t/relocate-home-directory/133626

Which I ultimately did in this way:

sudo fdisk -l

    (determine drive, probably /dev/sdb) 

sudo fdisk /dev/sdb

    n 
    p (the default) 
    1 (the default) 
    <enter> (the default, probably 2048) 
    <enter> (the default, some big number) 
    w 

sudo mkfs.ext4 /dev/sdb1
sudo mkdir /mnt/home
sudo mount /dev/sdb1 /mnt/home
sudo blkid /dev/sdb1

    (get the UUID string, be mindful that when you paste it later you'll have to remove the double-quotes) 

sudo rsync -av /home/ /mnt/home/
sudo nano /etc/fstab

    Add line (this UUID is an example):

        UUID=80fff7d0-184e-4d49-bb4d-282098bf7f3e /home ext4 defaults,relatime,usrquota,grpquota,quota,rw 0 2 

    Whole fstab would look something like this:

        # /etc/fstab: static file system information. 
        # 
        # Use 'blkid' to print the universally unique identifier for a 
        # device; this may be used with UUID= as a more robust way to name devices 
        # that works even if disks are added and removed. See fstab(5). 
        # 
        # <file system> <mount point> <type> <options> <dump> <pass> 
        # / was on /dev/ubuntu-vg/ubuntu-lv during curtin installation 
        /dev/disk/by-id/dm-uuid-LVM-TyLZvf3M8aGRPF4YjukB1I67mhyugjFxzfteEO1LYxELrdqnwOzgw9qN8hrB3cVy / ext4 quota,grpquota,usrquota,relatime,rw 0 1 
        # /boot was on /dev/sda2 during curtin installation 
        /dev/disk/by-uuid/24e58b7a-0439-4b03-a93e-e11fd52a1280 /boot ext4 defaults 0 1 
        UUID=99f17b50-7e96-410d-9c5b-954dcd248c7e /home ext4 defaults,relatime,usrquota,grpquota,quota,rw 0 2 

Ctrl-X and Y to exit and save
sudo umount /home
sudo mkdir /mnt/old_home
sudo mv /home /mnt/old_home
sudo mkdir /home
systemctl daemon-reload
sudo mount -a
df -h (check to see that "sdb1" in the answer) 

I noticed today that Virtualmin thinks I should recheck my configuration as its version may have updated. And when I do that one of the output strings says:

Quotas are not enabled on the filesystem /home which contains home directories under /home and email files under /home. Quota editing has been disabled

My fstab looks like this:

# / was on /dev/ubuntu-vg/ubuntu-lv during curtin installation
/dev/disk/by-id/dm-uuid-LVM-ZGyBSDlCriWXemlbEbnphTeUOqzYSn5RQrnL3Q39dpUzjnj3YeL3oj3749ahGid    /       ext4    rw,relatime,quota,usrquota,grpquota     0       1
# /boot was on /dev/sda2 during curtin installation
/dev/disk/by-uuid/61c79856-123c-48ba-99da-5ab9366cf6db /boot ext4 defaults 0 1
UUID=d4942993-5a7b-412c-8f52-a895ec88b71c /home ext4 defaults,relatime,usrquota,grpquota,quota,rw 0 2

I can fix this by changing the first and third lines of that thusly:

/dev/disk/by-id/dm-uuid-LVM-ZGyBSDlCriWXemlbEbnphTeUOqzYSn5RQrnL3Q39dpUzjnj3YeL3oj3749ahGid    /       ext4    rw,relatime,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0     0       1

UUID=d4942993-5a7b-412c-8f52-a895ec88b71c /home ext4 defaults,relatime,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 0 2

And then:

systemctl daemon-reload
sudo quotaoff -av
sudo rm -f /aquota.user /aquota.group /home/aquota.user /home/aquota.group
sudo quotacheck -avugm -f
sudo quotaon -av

But should I? (Like have I done the right thing by my Virtualmin system this way?)

Thanks.

It looks like all the commands you used were system commands? While I wouldn’t recommend it on a production system, I think you would have had to MOVE the partition to the new disk instead of recreating /home and rsyncing the contents. But this is from memory of long past installs.
