Hey guys,
So we have a standard Xi supermicro chassis with 33 or 36 six terabyte HGST SAS drives. So we have an unused 6TB drive that I'm trying to add as a spare, but when I go to volume manage extend the tank, and select the 1x6.0TB drive, it lists as Disk3 AND da67.
Okay so now I'm confused.
I assume that multipathing is some kind of redundancy feature. But I clearly don't understand it.
Anyways so to the real issue. DA29 has 29 uncorrectable errors on it. It's showing as failing under the multipath section of the server.
But when I go to volume status, disk 10 shows healthy. Again I'll do a big assume here and think it's healthy because of it's multipath, even though that makes 0 sense to me. How can a drive be bad but multipathing makes it should up at healthy.
We are running 9.3 freenas and we are terrified of updating in the middle of this project. Plus if someone hits update feature flags to the zpool it could break our data.
So basically i'm just asking how to I replace da29 with da67 even though they are multipath devices. I've attached some screenshots.

P.S. the volumed manager used to show disk3 AND da67. But I tried to replace Disk10 with Disk3 and now it's doing a resliver, and now disk3 no longer appears out of the volume manager.
