THE VIRTUAL SERVER HANDBOOK

Managing Quotas

Each Virtual Server has a disk quota that controls the amount of disk space

it can use on the host server. The amount of disk space that a Virtual Server

can use depends on the type of Virtual Server it is. The default quotas for

the types of Virtual Servers are listed below:

Server A: 70 Megs

Server B: 200 Megs

Server C: 500 Megs

The Virtual Servers quota can be increased at any time. Additional disk

space costs $1 per meg/per month. It is not always necessary to add

additional disk space when your quota is reached. It is very common for the

log files on your Virtual Server to be taking up excessive space or in other

cases, a hung process such as AFTPD could be using disk space.  These

issues will be discussed later in this chapter.

To increase your quota

Send an E mail to our office requesting that they add additional disk space.

Requests must be in 1 meg increments.

Sample Quota Command

To check the amount of disk space used on the virtual server telnet to the

server and from a command prompt type:

% quota

Disk quotas for user bob (uid 11487):

Filesystem blocks quota  limit  grace files quota limit grace

/usr       80030  281600 309760  255  55000 57750

Defining Quota commands

Filesystem This indicates that quota is checking for any files that you own

on the 

/usr volume

. You also own files on the 

/backup

volume

 but they are not counted against your quota.

Blocks

The blocks indicate the space that is currently being used. A

block is 1024 bytes. This server is using 81.9 megs of disk

space (80030x1024).

Quota

The disk space allowed a Virtual Server indicated in blocks.

This Virtual Server is a server C which has 275 megs by

default (281600/1024=275). The quota is a soft limit, meaning

the server continues to function when it reaches the quota.

Limit

The limit is a hard limit, meaning the server is unable to write

to disk when it exceeds this limit. Each Virtual Server is

allowed a 10% (275+27.5=302.5 | 302.5*1024=309760)

excess of its quota before the limit is reached.
