soong Posted October 13, 2020 Share Posted October 13, 2020 I'm looking over this page: The parity swap procedure It sounds like something I might want to do in the future, upgrade my 10TB parity drive to 12TB and then replace the the 10TB drive with a (working) 3TB drive. What's the advantage of using the swap method vs just doing it in two steps. 1) Upgrading the parity drive and then 2) Replace the 3TB drive? Quote Link to comment
JorgeB Posted October 13, 2020 Share Posted October 13, 2020 Parity swap is mainly for when you have a data disk disable and the spare is larger than current parity, it can be used to replace a healthy disk, but there aren't many advantages, it will take about the same time, and the array will be offline for hours during the parity copy portion, it could be considered an advantage the fact it only needs to read from all disk once, unlike twice with the normal upgrade method.
