VNX NAS Reclaim after archiving

Hi,

I have the following scenario:

1- I have a Unified VNX with 1 pool that has mixed drives (SSD, SAS, NL-SAS) with FAST. This pools is shared for BLOCK/FILE.

2- I want to create a NAS file system from that pool

3- From that filesystem, create shared folders

4- I want to use CTA to archive the files that are present in the shared folders to Centera

I want to know if AFTER archiving the files to Centera and replacing them with STUBs, can i "reclaim" back the freed up space and return it to the original pool (of point 1) so i can use them for something else?

Is there any documentation that describes the above scenario and how it can be achieved?


Thanks

JS

File system size will stay the same – you will have more space free in the file system but not in the pool

Is there any way to shrink the size of the filesystem on a VNX?

Re: VNX NAS Reclaim after archiving

If you use treequotas instead of file sytems for sharing out to different projects / departments that you can treat a fs more like a pool and use capacity that is freed in one treequota of the fs for a project in another treequota of the same fs
