VPS Quota Reconfiguration

VPS quota allows you to specify limits on two aspects of disk storage for your Virtual Private Server:
- the number of inodes a user or a group of users may have;
- the number of disk blocks that may be allocated to a user or a group of users.

To enable VPS quota for all Virtual Private Servers, you need to have:
- freevps kernel (build 1056256121 or higher) installed on the host box (steps 4-5 of VPS upgrade procedure);
- the Linux virtual server utilities (vserver-0.22-1 package) (step 8 of VPS upgrade procedure);
- new freevps-tools (freevps-tools-x.x-n package) installed on the host box (step 9 of VPS upgrade procedure);
- H-Sphere VPS scripts (hsphere-vps-x.x-n package) this is not necessary (step 10 of VPS upgrade procedure);
- new quota-3.03-2 package for Virtual Private Servers installed on all VPS.
Remember that quota-3.03-2 package is only for VPS installation!

Virtual Private Servers update, if hsphere-vps-x.x-n package is installed (see VPS upgrade) installs quota-3.03-2 on all existing Virtual Private Servers, enables quota on root partition (/) and configures VPS to turn on/off quotas at the VPS start/stop.

To install quota-3.03-2 manually, you need to:

• Download the quota-3.03-2 package from the FreeVPS site:
  
  Source package is available at:
  
• Install quota tools package on each of your VPS:

  # rpm -ivh --root <VPS_HOME> quota-3.03-2.i386.rpm

  Here,
  <VPS_HOME> - Virtual Private Server home directory;

To reconfigure quota on Virtual Private Server:

1. Enter Virtual Private Server:
   if hsphere-vps-x.x-n package is installed
   # cd /hsphere/shared/scripts/
   # ./vps-enter VPS_NAME
   or log into it with SSH:
   # ssh root@VPS_NAME (or # ssh root@VPS_IP_ADDRESS)
   or use vserver script (if VPS is running)
   # /usr/sbin/vserver <VPS_NAME> enter
here VPS_NAME - name of Virtual Private Server (VPS_IP_ADDRESS - VPS IP address)
2. If the /dev/hdv1 block special file does not exist, create it:
   touch /dev/hdv1
3. Modify /etc/fstab
   Partitions where quota is not yet enabled normally look like:
   /dev/hdv1 / ext2 defaults 1 1
   
   To enable user quota on a file system (for example, on the root partition), add "usrquota" to the fourth column - the one that contains the word "defaults" (refer to man fstab for details):
   /dev/hdv1 / ext2 defaults,usrquota 1 1
   
   To enable both user quota and group quota on a file system:
   /dev/hdv1 / ext2 defaults,usrquota,grpquota 1 1
   
   By default, your Virtual Private Servers are to be configured with user and group quota enabled on the root partition (/).
4. Make sure that the following line is present in /etc/mtab:
   /dev/hdv1 / ext2 rw,usrquota,grpquota 0 0
5. Activate quota software by running quotacheck. This will generate the files to maintain the quota databases (refer to man quotacheck for more details):
   # /sbin/quotacheck -avugm
   Here:
   -a - check quota for all mount points specified in /etc/fstab
   -m - creates quota files
   -u - check user quota
   -g - check on group quota
   -f - forces check
   
6. quotaon and quotaoff
   quotaon is used to turn on quota accounting:
   # quotaon -augv
   Run quotaoff to turn it off:
   # quotaoff -augv
   These commands are executed at the Virtual Private Server start and stop, respectively.
7. Check the quota information for mountpoints:
   # repquota -a
   or
   # quotastats
