SYNOPSISbldvldb.shDESCRIPTIONbldvldb.sh builds a new volume location data base VLDB. It uses the
/vice/db/hosts file to get a list of servers to use to retrieve the
current list of volumes. It gets the list from the /vice/vol/Vol‐
umeList file on each server. It combines the list into
/vice/vol/BigVolumeList and passes the combined list as a parameter to
the volutil makevldb command. This command produces a new VLDB in
/vice/db and updates the files AllVolumes and partitions in /vice/vol.
You must have root priveledges to run this command.
DIAGNOSTICS
This command can only be issued on the System Control Machine (SCM).
Bldvldb uses two mechanisms to get the VolumeList files from the vari‐
ous servers in /vice/db/hosts. The first is ftp. In order for this to
succeed, there has to be a file called ".anonr" in the directory
/vice/vol, which is globally readable and contains a line with the word
"VolumeList" in it. If bldvldb.sh is unable to get the file via ftp, it
will attempt to use the CMU RFS remote file system. If neither mecha‐
nism works, bldvldb.sh will skip over that servers volumes when build‐
ing the VLDB. The databases are propagated via the update protocol.
This takes up to five minutes. Attempts to access a new volume from a
client, prior to the propagation of all the databases to all servers,
may fail.
