Pro-289 Posted January 22, 2022 Share Posted January 22, 2022 I have a 3TB parity drive and some 3TB and 2TB data drives. I bought a 4TB drive that I now want to upgrade the 3TB parity. I just had some ultra dma crc issues with a few drives after moving around cables. One went disabled during a write I presume. I had a faulty/arcing power supply which I replaced. Changed out all my cables. Put some ferrite beads over my sata cables for the hell of it. I rebuilt that disabled drive and everything on it seems okay without error. I know I could disable the 3TB parity, assign the new 4TB as parity and rebuild it. But during that 12hr rebuild time frame if I have an issue with a data drive then I'm not protected from getting my array out of wack. Seems the easiest way if possible would be to install a new parity drive and have it copy from old to new in offline mode. Pull the old drive and start the array with out any rebuild, then run a parity check for good measure. When you do Dual Parity drives, are both drives exactly the same as each other? So could I add my 4TB as Parity 2 and have it rebuild onto that. Then remove my 1st 3TB parity and drop back down to a 1 parity drive array without rebuilding again? Quote Link to comment
