Questions related to node architecture, redundancy and system monitoring

Hi all

My network team are asking about storage on Sasha. It's currently taking 42gb of storage, is there anyway to clean this up?

Thanks

One of Sasha's main functions is archiving workunits. It removes workunits from the System Data Store (SDS) and archives them to disk on the Sasha server. Since the SDS is held in Dali memory, this reduces Dali resourse needs.

Once archived, these workunits are still available and can be found using the filter mechanism in ECL Watch. If needed, archived WUs can be restored from disk back into the main SDS.

Once WUs are archived, it is up to you what to do with the disk files. You can delete if you are certain they are no longer needed or you can move them to another storage location.

HTH,

Hi Jim

I hope you are well.

Do we need to stop any components before we ssh into the box and delete all the archived workunit xmls?

There shouldn't be a need to stop or restart anything. After a WU is archived, it is just a file on disk.

Since you can search archived workunits in ECL Watch, you could delete while a search is active, but that is unlikely and should be harmless.

The search is on-demand, so you could do your housekeeping to off hours.

HTH,

Jim
