Hot Swapping Drives

[kenster]

So, I made the plunge and ordered a 36 bay Supermicro chassis that I'll install FreeNAS on. I've done a bit of reading on how hot swapping drives works and it's not quite clear to me. Most people are saying the hardware needs to support it which makes total sense. I'm guessing Supermicro falls into this bracket. On the software side though, I'm still required to mark a drive offline and replace it in the ZFS pool? Any links to resources would be great.

As long as the hardware supports then you just (maybe offline then) replace via the GUI. See the User Guide

If you have a spare bay, put the replacement disk in it and do the replacement through the GUI. Once the resilver finishes, remove the old disk. This avoids any loss of redundancy while the disk replacement is in progress.

If you don't have a spare bay, offline the old disk, remove it, put the new disk in its bay, and do the replacement through the GUI.
