Best reconfig option
Posted: Fri Aug 23, 2019 1:00 am
Hello,
I am looking to get a little bit of guidance and some recommendations on what to do with my raid group. I have a TS-1679u-RP loaded out with 16 4tb drives in raid 6 with 1 hot spare. Slowly I am starting to have issues with the drives as they are getting older so I am replacing them with 8tb drives as they fail. Being a naive person back when I setup this big raid group thinking it was the best option not realizing that all 16 drive would need to be replaced to get more storage.
Now that I have enough extra storage to pull everything off and rebuild the raid group I just want to see if there are recommendations as to how I should do it. I was thinking something like 4
4 drive raid 5 groups into one pool. I get that I would lose one more drives capacity but I should be able see capacity increases after swapping 4 drive in one group rather than 16 drives and in theory might have a little more protection. But I might be wrong which is why I am asking. Also I am not sure if it is possible to do this without having to blow everything away but if there is a way I would prefer doing that. I have also attached a screenshot of the storage overview page.
One last question but this might be for another thread, with the TS-1679u-RP do I have to stick to the rack mount expansion units or can I pick up something like a REXP-1000 Pro that has the SAS connection on it?
If more info is needed to help make a recommendation please let me know. Thanks in advance
