.TH VENTI.CONF 6

.SH NAME

venti.conf  \- a venti configuration file

.SH DESCRIPTION

A venti configuration file enumerates the various index sections and

arenas that constitute a venti system.

The components are indicated by the name of the file, typically

a disk partition, in which they reside.  The configuration

file is the only location that file names are used.  Internally,

venti uses the names assigned when the components were formatted

with 

.I fmtarenas

or 

.I fmtisect

(see

.IR venti-fmt (8)).

In particular, by changing the configuration a

component can be copied to a different file.

.PP

The configuration file consists of lines in the form described below.

Lines starting with

.B #

are comments.

.TP

.BI index " name

Names the index for the system.

.TP

.BI arenas " file

.I File

contains a collection of arenas, formatted using

.IR fmtarenas .

.TP

.BI isect " file

.I File

contains an index section, formatted using

.IR fmtisect .

.PP

After formatting a venti system using

.IR fmtindex ,

the order of arenas and index sections should not be changed.

Additional arenas can be appended to the configuration.

.PP

The configuration file optionally holds configuration parameters

for the venti server itself.

These are:

.TP

.BI mem " cachesize

.TP

.BI bcmem " blockcachesize

.TP

.BI icmem " indexcachesize

.TP

.BI addr " ventiaddress

.TP

.BI httpaddr " httpaddress

.TP

.B queuewrites

.PD

See 

.IR venti (8)

for descriptions of these variables.
