I appreciate everybody's feedback, but I am still unclear on how to proceed. Here is a little more information about my setup. Specifically, here is my zpool status:
NAME STATE READ WRITE CKSUM tank DEGRADED 0 0 0 mirror-0 ONLINE 0 0 0 c10t0d0 ONLINE 0 0 0 c11t0d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c10t1d0 ONLINE 0 0 0 c11t1d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c10t2d0 ONLINE 0 0 0 c11t2d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c10t3d0 ONLINE 0 0 0 c11t3d0 ONLINE 0 0 0 mirror-4 DEGRADED 0 0 0 c10t4d0 ONLINE 0 0 0 spare-1 DEGRADED 0 0 0 c11t4d0 REMOVED 0 0 0 c10t6d0 ONLINE 0 0 0 logs mirror-5 ONLINE 0 0 0 c10t5d0 ONLINE 0 0 0 c11t5d0 ONLINE 0 0 0 cache c8d1 ONLINE 0 0 0 spares c10t6d0 INUSE currently in use In the past I have physically replaced the failed drive and then run these commands: # zpool replace tank c11t4d0 # zpool clear tank In this situation I would like to know if I can hold off on physically replacing the drive. Is there a safe method to test it or put it back into service and see if it fails again?

In the past I replaced the drive and and ran zpool replace and all was well. I am wondering, however, if it is safe to run zpool replace without replacing the drive to see if it is in fact failed. On traditional RAID systems I have had drives drop out of an array, but be perfectly fine. Adding them back to the array returned the drive to service and all was well. Does that approach work with ZFS? If not, is there another way to test the drive before making the decision to yank and replace? Thank you!
