Hi - as per the title, I need to remove 3 empty drives from my array. I have used the unbalanced plugin to move data around after purchasing some new disks and now want to remove the older unused disks for another project / use. Having read the docs and a few posts, I think the quickest way (with a small amount of risk) will be to use the first method in the docs: "remove drives then rebuild", i.e. stop the array, remove the 3 disks, re-start the array using the "retain current config" option, then let it rebuild the parity drive.

Am I reading it all right - is there anything else I need to consider?

That's what I would recommend, assuming all disks are expected to be healthy

Yeah, as far as I'm aware, they're all good and healthy! Thank you.
