April 13, 201313 yr I had a Quick search without much luck. I have a server running the latest 5.0 release with 4 x 2TB drives (1 parity, 3 data). I want to replace all drives with 4 new 4th drives that have been acquired. What's the easiest way to replace all all drives with new ones. I don't have another unraid server that would allow me to do a full copy and then just swap the drives. I'm assuming I need to replace 1 at a time starting with the parity and letting unraid rebild. Is that the only way ?
April 13, 201313 yr That's the way I would do it, I would also do an uncorrected parity check one after I rebuilt parity and two after each drive rebuild. It will take some time, but it will ensure your data is in check. Are you planning to preclear your new drives? This whole process could take a week or longer with preclear. at least this way you can stop and resume the process if you needed the data in the array without worrying about forgetting where you left off.
