The strange thing is that the pool is FAULTED while its part is merely
DEGRADED.
da4 failed reccently and was replaced with a new disk, but no resilvering is
taking place.
The correct sequence to replace a failed drive in a ZFS pool is:
zpool offline tank da4
shutdown and replace the drive
zpool replace tank da4
You can see a history of modifications you've made to your pool with:
zpool history
Probably you haven't gone through this sequence correctly and now ZFS is
still referring to the old/wrong UUID (the number you see instead of
da4) and therefore thinks the disk is unavailable.
Hope that helps,
Tiemen
