Want to enable quotas from within a vserver, nothing special, just plain old and good quota support? Then this might help you! First things first, you will need a vserver enabled kernel that you have made working and you need to add vroot support to it (In menuconfig it is in Device Drivers → Block Devices → Virtual Root device support).
After booting on the vroot enabled vserver kernel, you should have a directory /dev/vroot/ with 8 vroot devices (0-7) you can use to set up your quota, if you don't, then you may make them by mknod /dev/vroot/n b 4 n (where n can be from 0 to 7). If your Linux distribution uses udev, these will be at /dev/vroot[0-7] instead.
Initial Setup
Use vrsetup to tell the kernel what block device you want to handle quota for:
vrsetup /dev/vroot/0 [partition]
Where [partition] is your /vservers partition. For example, this could be something like /dev/hda5 if you're just using standard partitioning, or something like /dev/lvm/vserver0 if you're using LVM.
Setting Up Vservers For Quota
Setting up the vserver for quota is straight forward: (you need util-vserver 30.208 or newer) 1. Create a default mtab for the guest. To do this, add:
/dev/hdv1 / ufs rw,usrquota,grpquota 0 0
to /etc/vservers/<name>/apps/init/mtab
2. Add the quota capability to the guest vserver. Add:
quota_ctl
to /etc/vservers/<name>/ccapabilities
3. Copy the vroot device which we setup earlier to the vserver:
cp -af /dev/vroot/0 /vservers/<name>/dev/hdv1
Finishing the setup
1. Start your guest.
2. Inside the guest, run:
quotacheck -maugv
3. Still inside the guest, turn quotas on.
