4312 add EDA4000 Expansion Chassis / RAID Expansion
I'm unclear as to if it is possible to add an expansion chassis (EDA4000) to my 4312x system and grow the RAID storage capacity with XRAID currently configured? My 4312x system has 12 - 6TB drives a...
I had read that X-RAID is not supported across chassis.. If converted to Flex-RAID is it possible to extend across chassis? Data cannot be across multiple volumes? What I want to do essentially is grow my storage capacity utilizing the expansion chassis using my current dataset. I don't quite get conceptually if the same data can exist in multiple volumes? What would be the best approach to do this? I was thinking that vertical expansion using the 4312x would be the least invasive approach in that theoretically there would be no downtime? The issue is that I'm at 80% now. Thanks!
A volume is basically a virtual disk. Users don't see volumes, what they see is a list of network shares. That means that the volume structure is immaterial to them.
So the process here is
- switch to flexraid
- create a second volume on the EDA4000
- create some shares on that volume. These can be new shares, or you can move some shares to the EDA4000 from the existing volume on the 4312
To move shares from the RN4312 you
- create a share on the EDA4000 with a temporary name
- set up an rsync backup job on the NAS to copy an existing share ot the new one
- delete the original share
- rename the EDA4000 share to the match the name of the original share.
Note you can't move the "home" shares for your users - they have to stay on the original volume.
