"""
This script is an alternative to dpm-qryconf and dpm-getspacemd. It allows to
display information about both pools and space reservations.
This script is also a GIP provider (and not a plug-in), when used with option
--gip, generating information related to DPM storage areas (GlueSA) and
associated VO specific information (GlueVOInfo). Information on current
configuration is collected through DPM Python API.
GlueSA entries describes non-overlapping storage areas. There is one entry per
statically reserved spaces and one entry for the non-reserved space. In each
GlueSA, ReservedSpace described the SRM reserved space if any and TotalSpace
describes the actually available space (servers drained or down are not taken
into account). For GlueSA associated with DPM pools, pool capacity as returned
by DPM is reduced by the the amount of reserved space (reported in GlueSAs
associated with space tokens) in the pool.
If the space area is usable (shared) by several VOs, there is only one
corresponding GlueSA and one entry for each VO/FQAN in ACBR. Unreserved space
areas sitting on different DPM pools have distinct GlueSA entries.
GlueSAPath is not defined in GlueSA.
A GlueVOInfo entry is created for each VO/GlueSA combination defining the
following attributes :
- GlueVOInfoPath : home directory for the VO
- GlueVOInfoTag : space token (description) associated with the GlueSA,
if any
- GlueChunkKey : GlueSALocalID/GlueSEUniqueID of the associated SA
For unreserved space, if there is several GlueSA corresponding to different
DPM pools, there is one distinct GlueVOInfo for each GlueSA/VO combination.
DISCLAIMER : the output of this script is not intended to be parseable.
Formatting is subject to change. If you interested in getting
values displayed by this script, you are advised to use DPM
Python API. This script may be used as an example on how to
use it...
