NAME

servers - map server names to numbers

DESCRIPTION

Each file server has a file, /vice/db/servers, which maps server names to numbers. The server numbers are 8 bit numbers so a maximum of 256 servers can be supported. Once a server number has been assigned, it may not be reused. You should not reassign a server a new id without initializing the server.

The server numbers are used in too many places, probably the most important is in the creation of volumes. The server creating a volume uses its server number as the first byte of the four-byte volume identification number in order to ensure uniqueness.

NOTE: Replicated volume numbers must also be unique, so we reserve part of the range, 0-127 (0-7F hex), for this purpose. Real server numbers must not be allocated from the other subrange, and vice-versa.

The format of the file is the full server name (e.g. mahler.coda.cs.cmu.edu) followed by a tab and then the servers number. Any line beginning with a "\#" is considered a comment and is ignored. The following is an example servers file:

 MAHLER.CODA.CS.CMU.EDU          201
 GRIEG.CODA.CS.CMU.EDU           204
 HAYDN.CODA.CS.CMU.EDU           205
 WAGNER.CODA.CS.CMU.EDU          206
 DEBUSSY.CODA.CS.CMU.EDU         212
 SCARLATTI.CODA.CS.CMU.EDU       214
 ROSSINI.CODA.CS.CMU.EDU         215
 PUCCINI.CODA.CS.CMU.EDU         216
 GERSHWIN.CODA.CS.CMU.EDU        218
 SCHUMANN.CODA.CS.CMU.EDU        219

BUGS

The server numbers and replicated volume prefixes are pulled from the same number space. Separation is enforced only by convention.

This file and /vice/db/hosts should be combined.
