After I had built the system and realised this I pulled all the drives and spent 10 mins with a labeler and labeled every drive as well as logged where it was in the case.
That being said the best way to do this is to log all the serial numbers of the drives. As unRAID is kind of particular about each drive being in a certain spot, and also, if and when you want to upgrade a drive you really want to know which drive is which so you can tell unRAID when you are pulling a drive to upgrade it or replacing a filed drive. Now, a couple of things before we get any further, and I wish I had have known to begin with.ġ. You just need to run a little exe file to make it bootable (note: I wasn’t able to get this to work under Windows 7 Command Prompt, I had to dig up a WinXP machine in our primarily Mac shop to do this step) copy the unRAID software over to the drive and boot up. Installing the software was pretty straightforward. The last element was a 1 gig thumbdrive for the software and the unRAID pro licence which gives me up to 20 drives. So all up, the machine currently has about 6 terabytes of storage. So as we need more space I can take the older 500 gig drives out and slot in a 1.5 terabyte drive. That’s the great thing about unRAID, unlike RAID 5, the drives don’t have to match in any way, and can be upgraded individually at anytime. I also found two old IDE drives a 320 and a 500 gig to run of the PATA ports on the mainboard. Seeing as the way unRAID works is the Parity drive (the drive that provides protection for any of the other drives failing, needs to be at least as big as the biggest drive, I decided to hedge my bets and order a new 1.5 tb drive, then pulling apart a few of the WD cases I got a series of 1tb and 500 gig drives to throw into the Welland Trays. UnRAID is in the bottom right below the Xserve and SANĪs for storage, we have a bunch of SATA drives sitting in about 20 Western Digital external drive cases that are no longer being used with the new SAN going on line, so the plan was to re-purpose a few of them to begin with.
I also added this nifty Welland drive bays, basically they allow you to swap in and out SATA drives without having to mount them in Caddies first, a nice feature given that the whole point of this unRAID in not only does it provide RAID like Redundancy but it also allows easy upgrading of individual drives as space is needed. All sitting in an Antec Rack Mount Case with 6 accessible drive bays as well as a further 6 3.5 bays. As this was to be used as a second line of defense if our main array were to fail in any way, and the hot spare drives had a problem, or more likely as a way of covering for human error, I decided to lash out and go for pretty much all new components.Ĭore 2 Duo 3.0 gig CPU, 8 gig DDRII RAM, a nice Asus mainboard with onboard 8 SATA ports and a couple of IDE ports as well. OK, so after a lot of messing around I have finally gone ahead and built my unRAID.
