The Eloquence database server uses the following
approach to allocate disk space from a volume.
-
First, all available volume space is used.
If you add a data volume with its minimum size which
is about 2.5 MB, the new space within these 2.5 MB
will be used before any of the volumes are grown.
-
If there is no more volume space available, the first
volume which is not already at its maximum size is grown.
If this does not satisfy the current request for
additional space, the next volume is grown.
The volumes are ordered by means of an internal order
information. The first volume is always the one you
initially created with dbvolcreate. The order of the
other volumes is determined by the order of their
creation with dbvolextend.
