Hello
We have MSDP 7.6.0.3 on RHEL 6.5 and we have a problem with space recalamation.
Current front end data is apparently no more than 3TB, images were expired in catalog, however, the logical catalog space and space usage on disk is not decreasing.
We could not identify any obvious reason, we have no errors in image cleanup jobs, no errors in storaged.log, queue processing is performed daily, compaction state is on, data integrity check is enabled with 30 days parameter. As it seems some containers get cleaned --> as if the space reclamation worked for images currently backed up but we can not clear the expired ones.
We ran nbdelete -allvolumes -force several times.
No incidents or errors on the MSDP host server either.
Could anyone advise what checks we could still perform? Any ideas of what may be causing this issue? I am awaiting to have the necessary authorizations to open a support case but anyway I would be grateful for this forum`s users opinion.
