Hi, folks,

testing zfs. I’d created a zpoolz2, ran a large backup onto it. Then I
pulled one drive (11-drive, one hot spare pool), and it resilvered with the hot spare. zpool status -x shows me state: DEGRADED
status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Replace the device using ‘zpool replace’.

but when I try zpool replace export1 /dev/sdb1, it says, nope, invalid vdev specification use ‘-f’ to override the following errors:
/dev/sdb1 is part of active pool ‘export1’

Any idea what I’m doing wrong?
