[OpenIndiana-discuss] zpool vdev membership misreported

[George Wilson]

Justin,

More than likely c3d1 contain a label from an old pool. If you run 'zdb 
-l /dev/dsk/c3d1s0' you should be able to if one exists. If does contain 
information for an old pool then using the '-f' option when attaching 
will solve your problem and relabel the device with the new pool 
information.

You could also do a 'zpool import' to see if c3d1 shows up with 
information about an exported pool.

Thanks,
George
