An important part of setting up a new storage array is testing how to recover from common failure scenarios. This is the procedure to replace a failed drive. Documented here for a time when I might need to use the procedure in anger. A zpool status showing the failed drive: root@thor:/home/wayne# zpool status tank pool: tank state: DEGRADED status: One or more devices are faulted in response to persistent errors. Sufficient replicas exist for the pool to continue functioning in a degraded state.

The IBM M1015 is the go to Host Bus Adapter (HBA) for enthusiasts wanting a reliable and reasonably priced HBA for systems using advanced filesystems such as ZFS. I acquired a number of these cards for my file-server upgrade. I needed cards to support my new Norco RPC-4224 Chassis. There is a lot of discussion on line about these cards, and re-flashing them to remove the boot & raid firmware.
