createvol_rep(8)	    System Manager's Manual	      createvol_rep(8)

NAME
       createvol_rep - create read-write replicated volume

SYNOPSIS
       createvol_rep  <volume-name>  <server>[/<partition>]  [<server>[/parti-
       tion]]... [<volume-id>]

DESCRIPTION
       createvol_rep is	a front	end to volutil create_rep and is used to  cre-
       ate  a  Coda read/write replicated volume. The invoker must specify the
       volume name (_volume-name_), and	the  server(s)	on  which  the	volume
       should  be created. (_server_[/_partition_]), the partition name	is re-
       quired when the server manages more than	one data partition. Finally an
       replicated _volume-id_ can be specified.

       createvol_rep	 first	  checks    in	   /vice/vol/AllVolumes	   and
       /vice/vol/VRList	to see if the volume name already exists.  If not,  it
       uses the	volutil	create_rep command to create the volume	at each	of the
       replication sites.  It then rebuilds  the  Volume  Location  Data  Base
       (VLDB) and the Volume Replication Data Base (VRDB).

       The optional replicated _volume-id_ specifies the "replicated" volumeid
       of  the	volume	being  created.	  By  default,	the   volume   id   in
       /vice/vol/maxgroupid  is	used.  Each time it is used it is also updated
       by adding 1 to it.

       After the replicas are created at each replication site,	a new VLDB  is
       built  automatically  using  bldvldb.sh(8),  and	the Volume Replication
       List in /vice/vol/VRList	is updated.  The VRList	contains one line  for
       each  replicated	 volume.   Each	 line  specifies the replicated	volume
       name, replicated	volume id, number of replication sites,	and the	 local
       volume  id at each replication site.  This file is now used to create a
       new Volume Replication Data Base	(VRDB)	using  the  "volutil  makevrdb
       /vice/vol/VRList" command.

EXAMPLES
       To  create a replicated volume "coda.rep" on 3 sites foo, bar and  gorp
       use:

       createvol_rep coda.rep foo bar gorp

       To assign a predetermined replicated volume id, use

       createvol_rep coda.rep foo bar gorp 7F000003

       where "7F000003"	is the replicated volume id.

DIAGNOSTICS
       This command must be issued at the System Control Machine (SCM).	 Also,
       it  must	 be invoked with effective user	id of root.  This command does
       not check for return codes from the volutil  create_rep	command.   The
       invoker	must  check  /vice/vol/VRList and /vice/vol/VolumeList at each
       replication site	to see if the volume was created.

FILES
       /vice/vol/VRList
	      contains information on replicated volumes

       /vice/vol/VolumeList
	      name of volume created at	each site is appended to it

       /vice/db/VRDB
	      is used to describe the replicated volumes in terms of its  non-
	      replicated members.

       /vice/vol/AllVolumes
	      is used to check if volume exists

       /vice/vol/maxgroupid
	      is used to assign	a volume id to the replicated volume
