quota on a remote server (NFS) [#59572]

Hi @all,

I've got a question about quota with virtualmin on a remote server (NFS) .

Setup: virtualmin host: IP: 10.203.30.10/16 path for virtualmin domains to create: /home/cluster fstab: 10.203.20.20:/cluster/nfsshare /home/cluster nfs4 defaults 0 0 NFS Server: IP:10.203.20.20/16 nfs share: /cluster/nfsshare dev for /cluster: /dev/drbd0

So I edit Webmin -> System -> Disk Quota -> 'Module Config' -> System configuration like this:

Command to list users on a filesystem = ssh root@storage001 -i /root/.ssh/key_root repquota -u -v /dev/drbd0

Command to list groups on a filesystem = ssh root@storage001 -i /root/.ssh/key_root repquota -g -v /dev/drbd0

Command to edit user's quota = edquota -r -u -f /home/cluster/

Command to edit group's quota = edquota -r -g -f /home/cluster/

Command to set a user's quota = ssh root@storage001 -i /root/.ssh/key_root setquota -u

Command to set a group's quota = ssh root@storage001 -i /root/.ssh/key_root setquota -g

Command to check a user's quota = ssh root@storage001 -i /root/.ssh/key_root quota -v -u -f /cluster

Command to check a group's quota = ssh root@storage001 -i /root/.ssh/key_root quota -v -g -f /cluster

Command to copy a user's quota = ssh root@storage001 -i /root/.ssh/key_root edquota -u -p

Command to copy a group's quota = ssh root@storage001 -i /root/.ssh/key_root edquota -g -p

Command to turn on user quotas = ssh root@storage001 -i /root/.ssh/key_root quotaon -u /cluster

Command to turn on group quotas = ssh root@storage001 -i /root/.ssh/key_root quotaon -g /cluster

Command to turn off user quotas = ssh root@storage001 -i /root/.ssh/key_root quotaoff -u /cluster

Command to turn off group quotas = ssh root@storage001 -i /root/.ssh/key_root quotaoff -g /cluster

Command to check quotas = ssh root@storage001 -i /root/.ssh/key_root quotacheck -u -g /cluster

Command to edit user grace times = ssh root@storage001 -i /root/.ssh/key_root edquota -f /cluster -u -t

Command to edit group grace times = ssh root@storage001 -i /root/.ssh/key_root edquota -f /cluster -g -t

If I run th comands from the console every thing return the expected result. But Virtualmin -> System Settings -> Re-Check Configuration says:

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

What dose Virtualmin check ? Is there a logfile about the check? Could this work at all? Are there any experience about this? Thanks!

Virtualmin checks the /etc/fstab file to see if quotas are enabled for the filesystem, via usrquota and grpquota options.

So because of mount.nfs(8) don't support options for grpquota/usrquota there is no possibility to get virtualmin to work with quota on NFS.

Even /etc/fstab = 10.203.20.20:/cluster/nfsshare /home/cluster nfs4 rw,suid,dev,exec,auto,nouser,async,usrquota,quota,grpquota 0 0

with 'mount -as' won't be realised by virtualmin.

Actually, when a custom quota command is in use, Virtualmin shouldn't care about the filesystem options.

In your /etc/webmin/virtual-server/config file, does the line quotas=1 exist?

root@host000 /etc # grep quotas= /etc/webmin/virtual-server/config

quotas=1 mail_quotas= show_uquotas=0 hard_quotas=1 group_quotas= home_quotas= show_quotas=1

Make sure you also set quota_commands=1 in that file.

If I do this quota_commands=1 an edit under Virtualmin -> Virtualmin Configuration -> Quota commands -> Command to set a user's quota = ssh root@storage001 -i /root/.ssh/key_root setquota -u /cluster

In /etc/webmin/virtual-server/config I find: quota_set_user_command=ssh root@storage001 -i /root/.ssh/key_root setquota -u /cluster

but der Re-Check Configuration said: External quota commands are enabled, but the command to set a user's quota is not defined or does not exist

I also tried : quota_set_user_command='ssh root@storage001 -i /root/.ssh/key_root setquota -u /cluster'

Ok, there's a bug in Virtualmin - it expects the command to be a single script rather than a long ssh command. The work-around is to place your commands into short shell scripts in /etc and then references those in the Virtualmin config (use $* to refer to the list of command-line args to the script).

Thanks for this! I created this:

add to Webmin -> System -> Disk Quotas -> Module Configuration -> System configuration -> Command to check quotas /etc/vmin-quota_check = ssh root@storage001 -i /root/.ssh/key_root quotacheck -u -g $* -a

I see all commands in /etc/webmin/virtual-server/config and the Re-Check Configurations seems to be ok. Great! The only thing I dont see is the useed quota in virtualmin.

Any idea? Can you say what virtual min passes to 'the command' I saw foe example to Virtualmin -> Command to set a user's quota on creation it only passes username 1024 1024 but the comand expacted username <block-softlimit> <block-hardlimit> <inode-softlimit> <inode-hardlimit> -a

You may need to repeat some of the args - in your script, you can use $1 for the first are, $2 for the second and so on.

Thast clear but what passes virtualmin to the "comands" ?

Can I see someware what actions are done from virtualmin?

Submitted by JamieCameron on Wed, 12/05/2018 - 23:29 Comment #13

You can see docs on what args are passed to the commands on the Virtualmin Configuration page, by clicking on the option names.
