[OmniOS-discuss] [zfs] FMD fails to run

Mon Mar 19 13:24:53 UTC 2018

Even unloading all the modules except 'fmd-self-diagnosis' which will not
unload, fmd still dies as soon as I plug in the JBOD.

# fmadm config
MODULE                   VERSION STATUS  DESCRIPTION
fmd-self-diagnosis       1.0     active  Fault Manager Self-Diagnosis

# fmadm unload fmd-self-diagnosis
fmadm: failed to unload fmd-self-diagnosis: module is in use and cannot be
unloaded

Looks like I'm dead in the water to make this work with Illumos until this
bug is fixed.
