September 19, 201510 yr I'm running version: 5.0.5 Disc 6 is showing as "DISK_DSBL". I want to scrap this drive, increase my unraid capacity and parity size at same time. I have a Asrock B75 motherboard It has 8 sata in total. All are utilised by 6 unraid drives, 1 parity and 1 cache drive. I'm also down to molex power on my PSU so with need to get some adapters to power future drives I have 1x PCI Exp 3.0 and 1x 2.0. I want at least a 3 slots on the card sata card to give myself a bit of head room in the future? Which cards should I consider? My case is also out of hard bays but I have some spare cages out of other cases I can mount. What is the best order to add the new drives and removing Disc 6? After this I would like to clean up my unraid and upgrade to version 6. Always need to stop the array by command line. But one issue at a time
September 19, 201510 yr Since you said one issue at a time (a very good approach), start by testing a new 3TB drive by preclearing it, and use it to rebuild your disabled 2TB drive. Another approach would be to get a new larger parity drive, test it with preclear, and then use the swap disable procedure to copy parity to the new parity drive and rebuild the disabled drive onto your old parity drive. Either approach will get you back to a protected working state and you can worry about adding ports later.
September 19, 201510 yr Author Okay so skip sata card for now. Get bigger parity parity, preclear it and then add it. Saves me money on another drive and card for now. Win! However, I don't think I want to be doing any rebuilds. This is not a recent issue. Unsure of last parity check since this issue cropped up and because Disc 6 is disabled it no longer does parity checks I have moved a number of files to and from many discs to clear stuff off disc Disc 6 Couldn't I just back up what I needed remaining off Disc 6 disable it and then look at increasing the parity? Thanks
