February 27, 201313 yr Hello, I just setup my first unRaid build. Currently i have 3 drives. 3x 3TB Seagate drives. 1 Parity, 2 data. Ive been following the Config tutorial. I have already done a preclear, and received good results. The next steps say to assign a drive to the parity slot, and your data slots. and then to click START and at this point, any unformatted drives will show that they are unformatted. Then you should click FORMAT and let the parity check complete. I clicked format, however, the PARITY drive never showed up as an unformatted drive. SHouldnt this have been formatted as well? Additionally, during the first parity check, should the ball be orange next to the Parity drive? my 2 data drives have green balls. SOrry for the noob questions. appreciate the help
February 27, 201313 yr parity does not get formatted like a data drive - it will never show up as unformatted - you are good to go.... Myk
February 27, 201313 yr Author Thanks for the quick reply. Im also assuming the orange ball during parity check is normal??
February 27, 201313 yr Thanks for the quick reply. Im also assuming the orange ball during parity check is normal?? The first parity check, yes, because it has no idea what's on the parity compared to what's on the data drives, which, is why you're running the check. It should turn green the second it's done, and, personally, I ran another read only parity check just to verify the first one went okay.
February 27, 201313 yr It should turn green the second it's done, and, personally, I ran another read only parity check just to verify the first one went okay. Actually, the first time you calculate parity you are only writing to the parity disk. You have no idea if it is readable. In order to be certain you can READ the parity disk you must then perform a subsequent parity CHECK. This will then read what you've written and ensure the disk was written properly. Without this step, the first time you'll find you have a defective sector on the parity disk is when you try to use it to reconstruct a failing disk. That is NOT the best time to discover it was not able to be read, and your data could be lost.

February 27, 201313 yr Author Many thanks to all for the replies! I am up and running...well...Running the second Parity check now Appreciate everyone willingness to help out in this community!!! I hope to provide assistance soon!!!

I hope to provide assistance soon!!! Just a note:- It's recommended to periodically run a parity check once every month or so, there's quite a few plugins that do it, but, SimpleFeatures has it built into a nice web-GUI.
February 27, 201313 yr Already loaded If you're talking about loading simplefeatures, it's not enabled by default, just saying. If you're talking about loaded (and configured!) any of the plugins that do it (Including simplefeatures), then, good.
