Hi Guys,
We have a 15 drive raidz2 freenas sharing out to some video editors over SMB. Everything has been great but they are running out of storage space.
So I installed an expansion chassis with 20x 10TB drives via a 12G SAS cable. Wow that’s a big jump.
I’m thinking of expanding the pool across both chassis so that we don’t have to recreate the user permisions and folder structures all over again. What do you guys think?
Should I expand the current pool or create a new pool?
My setup is two super micro chassis. The head unit is 15 drives raid z2 with 128gigs of RAM. The expansion chassis is just a empty chassis with 20x 10TB HDDs and a SAS card.
I’ve connected the two chassis via a 12Gig mini SAS cable.
I’m thinking of making 2 groups of Raidz3 on the expansion chassis and then expanding into the current pool.
If something goes wrong is there a way to revert to the previous model, basically to remove the SAS chassis and put it back the way it was?
So I guess I have two questions. My first question is should I expand the current pool across the two chassis’ or should I make a new pool?
Then my second question is: if I decide to expand the current pool and let’s say the performance gets worse(which I doubt) but if it does, then is there a way to remove the 20x10TB drives from the hypothetical new pool? Or would I be stuck with my decision?
Thanks for any advice
