Hi all I have this pool with 11 7-drive RAIDz2 VDEVs, all WD Black 2TB (FASS) drives. Another drive died recently, and I went to replace it. zpool offline, cfgadm -c unconfigure, unplug, devfsadm, zpool replace. Now, after this, I realize the resilver to a spare hadn't finished, so now it's tel

Hi Paul, I've seen some spare stickiness too and its generally when I'm trying to simulate a drive failure (like you are below) without actually physically replacing the device. If I actually physically replace the failed drive, the spare is detached automatically after the new device is resilve
