Sinopsis Posted July 6, 2021 Share Posted July 6, 2021 If I'm ok taking the risk, can i just pull both my parity drives and throw new ones in and let it rebuild them both @ the same time? Quote Link to comment
Sinopsis Posted July 6, 2021 Author Share Posted July 6, 2021 Just stop the array, pull the 2 parity drives, replace and start the array? Quote Link to comment
trurl Posted July 6, 2021 Share Posted July 6, 2021 No point in trying to hot swap with Unraid since it won't do anything until you assign the new disks, and you can't make any disk assignment changes with the array started. So no good reason to do the drive replacements under power. Shutdown, replace drives, boot up. It will show the original parity drives as missing. You will have to assign the replacements to the parity slots before you can start the array to build parity. As long as you don't change any of the data disk assignments you should be good. You don't want to assign any data disk to any parity slot or it will be overwritten with parity. Also, make sure you don't disturb the connections on any other disks. Double check all connections before rebooting. Quote Link to comment

casperse Posted October 26, 2021 Share Posted October 26, 2021 @trurl you wrote above that you can just replace both drives (I also need to replace both my Parity drives with larger ones 🙂) Would it be safer to replace and rebuild with only one parity drive at a time? or is the risk the same?

JonathanM Posted October 26, 2021 Share Posted October 26, 2021 One at a time is safer, since they operate totally independent of each other. Takes twice as long, but definitely safer. 1 Quote Link to comment
