cPanel Disk Quotas for LXC - need help

[Mario Aldayuz]

I am running CentOS 6 inside of an LXC container with cPanel installed and cannot get user/account quotas to work properly. Is there a fix for this? Are they supported by LXC containers? Is anyone else running cPanel inside of an LXC through Proxmox?

 

[dietmar]

latest versions of pct supports user quotas (pve-container>=1.0-44)

 

[Mario Aldayuz]

OK, I have updated the packages to >1.0-44

How do I enable the quota, or is it automatic? cPanel says "No filesystems with quota detected."

 

[dietmar]

On the GUI, got Container/Resources/RootDisk -> select "Enable Quota", stop/start the container

 

[Mario Aldayuz]

OK - I do not see this option. I have "Edit" (greyed out) and "Re-size Disk"

 

[Mario Aldayuz]

I have updated all three nodes in the cluster, rebooted all, and still do not see the option?

Hello, have you found a solution for this? I do not see the option to enable quotas.

Did you clear your browser cache after updating? Maybe your browser still uses the old version of the JS client where the edit button was disabled for container disks?

 

[Mario Aldayuz]

I did. Is this specific to a type of file system or storage?

I did. Is this specific to a type of file system or storage? I have tried multiple browsers, including cache clearing of all of them.

I am running a 3 node cluster, all nodes have been updated and restarted.

Any help? The button is still not enabled for editing the storage to add quota...

 

[wbumiller]

Uh... does your storage have a capital in its name? Somone forgot an /i while parsing storage names and ended up producing a case sensitivity issue there... https://git.proxmox.com/?p=pve-manager.git;a=commit;h=e975f6c141459bb09554749782103614a18930a8

 

[Mario Aldayuz]

No - I don't believe so. Generally everything I do is lower case.

I'm pretty confused as to why this isn't working, and hope we can get it figured out soon!

 

[wbumiller]

What package versions are you on now and what storage do you use for the disks you want to enable quotas on? And the container config would be useful, too (pct config $vmid)

 

[Mario Aldayuz]

The newest package versions (as of this morning 8am EST).

The option now appears - it can be enabled for all storage types but the container errors out when using LVM over iSCSI.

root@node2:~# pct config 101
arch: amd64
cpulimit: 4
cpuunits: 1024
hostname: ct101.imws3.com
memory: 20480
net0: bridge=vmbr0,gw=XXX.XXX.XXX.XX,hwaddr=62:63:61:61:34:30,ip=XXX.XXX.XXX.XX/XX,name=eth0,type=veth
onboot: 1
ostype: centos
rootfs: lvm1:vm-101-disk-1,size=150G
swap: 2048

It does work when using local storage. What storage types will work with LXC quotas, and is there an easy way to migrate to other disks/storage types?

storage types: with the next updates all ext4 based storage types except for passed-through /dev nodes (a patch for that is already waiting) should™ work (If I'm not mistaken then that should be all except for bind mounts, zfs subvolumes or when using `size=0`).
as for migrating storage: not yet but soon, that part's overdue by now, sorry...
about the last error: Right, the updates to the autodev hook didn't make it into the last package. Will be fixed with pve-container>=1.0-54 where LVM devices will appear the usual way with /dev/dm-* as node and the usual named symlinks in /dev/mapper/.

Hello, I've restores a OpenVZ container vzdump in a Proxmox 4 with LXC.
It's a CentOS container with cPanel.
quotas option is enabled.
But I get this error:

edquota: Cannot open quotafile //aquota.user: No such file or directory
edquota: Cannot open quotafile /backup/aquota.user: No such file or directory

And all cpanel account show that are using 0M

Any idea?

Does this work on ZFS containers that are on ZFS raid1 type array? I assume not.
