For one thing, it returns immediately (which is unexpected since DIOCGDELETE ioctl is a blocking call). On the other hand, pre-existing filesystems continue to be usable: # zpool create -m none -f test /dev/ada1s1 # zpool export test # newfs -E /dev/ada1s1 [...] Erasing sectors [128...16773119] [...] # zpool import test # >How-To-Repeat: >Fix: I don't know the fix, but it seems most likely a kernel bug (I've verified that DIOCGDELETE ioctl is indeed being called). >Release-Note: >Audit-Trail: >Unformatted:
