Hello,

Approaches/solutions and critique 1- add one by one a 'spare' and 'replace' raid member critique: - seem to me long and tedious process - cannot/will not run in parallel 2- add all the spares at once and perform 'replace' on members critique - just tedious - lots of cli commands which can be prone to mistakes. next ones assume I have all the 'spares' in the rig 3- create new arrays on spares, fresh fs and copy data. 4- dd/ddrescue copy each drive to a new one. Advantage can be done one by one or in parallel. less commands in the terminal.
My last drive upgrades were done in a chassis that had two extra hot swap bays. So I could do two at a time. I wanted to keep careful track of roles, so I started a replace after each spare added, to ensure that spare would get the designated role. After it was running, I would --add and --replace the next. After the first two were running (staggered), it was just waiting for one to finish to pop it out and start the next.
After completion, I used --grow to occupy the new space on each. Took several days, but no downtime at all. Phil
