partition_map(4) ToolTalk Commands partition_map(4)NAMEpartition_map - tell rpc.ttdbserverd(1M) to locate its databases in an
alternate file system
SYNOPSISpartition_mapDESCRIPTION
For each filesystem that rpc.ttdbserverd needs to store information
about, it creates a directory called TT_DB at the mountpoint of that
file system. In that directory it creates the databases it needs to
store its tables and indices. If the partition is not writable, then
rpc.ttdbserverd can be told, via partition_map(4), to create the data‐
bases in another file system.
The partition_map file is called "partition_map" and resides in
/etc/tt. If $TT_PARTITION_MAP is set, it is used in place of
/etc/tt/partition_map.
rpc.ttdbserverd(1M) reads the partition map upon startup and rereads
the map if it receives signal USR2.
Format rules
The format rules for a partition_map are:
1. Any line beginning with a "#" or white-space and a "#" is a comment.
2. Blank lines are comments.
3. Words are delimited by white space.
4. The first word in a non-comment line is the partition from which to
map.
5. The second word in a non-comment line is the partition to which to
map. Although the TT_DB directories are by default at the root of
their file systems, the user may in fact map to any local filename
that is writeable by UID root.
ENVIRONMENT
TT_PARTITION_MAP
If $TT_PARTITION_MAP is set, it is used in place of /etc/tt/par‐
tition_map.
