Can I somehow disable the ZIL in an irresponsible way, to establish

unmount a zfs filesystem you want to test by: zfs unmount pool/fs1
then do: echo 'zil_disable/W1 | mdb -kw'
then mount the filesystem again: zfs mount pool/fs1
do your testing
to enable zil again, unmount the filesystem then: echo 'zil_disable/W0 |
mdb -kw' and mount the fs again.
