Absolutely. It's also give me a chance to blow the dust off them. They're on 24/7 and the server chassis doesn't have filter material in these pull-out trays, so I added some. With them running for almost 10yrs, vacuuming only sucks out so much dust... it's time to replace. :D
Not having the machine off would cause mdraid to fail the raid as the drives are removed, and not having it off when inserting them would make it activate them one at a time which may or may not quite work.
Yep. I'm aware. I was soliciting for any bad installer behavior on the part of anaconda and the like.
I have done my updates without pulling the drives (at least 1-2 fedora reinstalls) and just made sure to not let anaconda mess with the larger raid disks. Without the conf file it will still find the raids, it just won't have the same md* names. I have also installed a disk elsewhere and made sure the dracut config was setup to include all drivers (change to hostonly=no). 6 does hostonly=no, 7 does hostonly=yes, not sure what 8 does by default.
Thanks for chiming in! -Ben
