Expand a pool capacity

Hi All,

I've a pool created of 100GB and I need to expand this capacity to 500GB. Can this pool be expanded on the fly? if yes, could you please detail out the steps or a reference guide?

thanks in advance,

Samir

Hi,

Pool Capacity is defined and reported in terms of the front-end or application view, reporting the capacity and number of C-Clips and User Files that different applications wrote to Centera, minus what they deleted.

Unlike Raw Capacity, Pool Capacity does not depend on the protection scheme being used nor on single instancing, and it does not fluctuate as processes such as regeneration and garbage collection process files.

Each time a C-Clip is written to a pool, pool capacity is added; each time a C-Clip is deleted, capacity is removed. The amount with which the pool capacity is adjusted is the sum of the size of all the User Files embedded or referenced in the C-Clip .

use the command "Show pool detail " and see if there is any Free Pool Capacity (Hard Stop):?

Regards

Hi,

I agree with the above answer,but you can also use the command given below to set the Pool size on the cluster.

update pool access

Please note that the size given to the Pool is always virtual and not a gauranteed space.

Hi

Additionally to the statement above the update pool access command allows you to set a quota which is either a soft (alert) quota or a hard (hard stop) quota. If both are available depend on your version of CentraStar. If only one is available it is the soft quota.

If you can use all of your quota does depend on the system having the space you need available. The actual capacity used for your objects will depend on the protection scheme and single instancing and is raw unlike your pool capacity which is application written capacity.
