Centera Pool Quota Information
The CLI function specific for a pool "show pool detail " gives the specific information about a pool. Is there a function provided in the EMC Centera SDK that woul provide a similar output. What I am looking for is the Pool Quota.
The Pool function FPPool_GetPoolInfo() that fetches the information about the total free space avaliable in a cluster. Hence this does not serve the purpose.
Kindly let me know if there is any method/function available in the SDK for getting free and total space information specific to a pool.

There is no API call that you can use to determine the space usage stats of the VP you are connected to.

It's worth pointing out that the virtual pool quotas are not enforced by Centera. If a pool reaches its quota it will continue to accept writes without interruption but it will be reported as over quota through the management UI.

Hi Mike,
I also have another query now regarding centera management perspective.
I understand that if the quota limit of a pool is reachead the data gets written into the common centera pool. So, now in future if the admin person wants to delete a pool using the "delete pool " what would happen to the files written to the general pool. How is the cleanup of these files ensured?

you cant delete a non empty pool. Also note that even if you delete all the clips in your pool there still will be reflections in the pool which will stop deletion. You would need EMC support to come in and delete the reflections in a pool before you could delete it

Hello Saurabh,
I apologize if I misled you with my previous response, and I think it's important to clear up a misonception in your post so that others are not misled. You wrote:
This is not true. Virtual pools on Centera are unlike volumes or LUNs on other types of storage, they are only logically represented in the storage system (not physically). All of the content (clips and blobs) on Centera is co-mingled on the disks of the storage nodes regardless of the virtual pool to which they were written. If a quota limit is reached on a virtual pool there is no change to the ingest behavior of the system; clips still get committed to the home pool of the profile in use by the application (whether that pool is is over or under quota). The only effect of this condition would be notifications to the system admin about an over-limit pool. When the entire Centera is out of available capacity (and/or object count) is the only time the system will reject new content writes.
