/vice/vol/VolumeList Holds partition and volume information for volumes for which this server is custodian. This is file is generated by codasrv .
/vice/vol/groupid is maximum replicated volume id allocated so far.
HOSTS (text)
- Entries describe volume storage groups: id hostname1 hostname2 etc. Stored in /vice/db/VSGDB
- /vice/db/hosts servers should be in this file. Servers found in the VSGDB are checked to be in this file before proceeding to make a volume.
- /vice/db/servers contains an id for each server.

Createvol_rep works as follows: Parameters are: volname vsgaddr partition-name [groupid]

check we are the SCM
Check that the volname doesn't appear in AllVolumes or VRList
Get the list of servers from the vsgaddr using the VSGDB
verify the servers against /vice/db/hosts
get a new replicated id for this replicated volume using the /vice/vol/groupid file
use volutil to create the volume on each host, using the partition, volumename and groupid acquired before. Note that each server now assigns a volume id for this newly created volume. It dumps
