servers(5) servers(5) NAME servers - map server names to numbers DESCRIPTION Each file(1,n) server has a file(1,n), /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(1,8) too many places, probably the most important is in(1,8) the creation of volumes. The server creating a volume uses its server number as the first byte of the four-byte volume iden- tification number in(1,8) 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(1,n) 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 FILES /vice/db/servers BUGS The server numbers and replicated volume prefixes are pulled from the same number space. Separation is enforced only by convention. This file(1,n) and /vice/db/hosts should be combined. SEE ALSO vrdb (5), vsgdb (5), maxgroupid (5), hosts (5) AUTHOR Maria R.
