Host hook not working (5.9)

Community Support General

Hi,
I am trying to test host hook on Opennebula version 5.9 , running on Ubuntu 18.04 hosts.
I have disabled fencing on host error hook script, but getting below error on host failure.

I have disabled the fencing and changed the $TEMPLATE to $ID, since I was using $ID on previous version of openenbula

cat /usr/share/one/examples/host_hooks/error_hook
ARGUMENTS = "$ID -m -p 5 -u"
COMMAND   = "ft/host_error.rb"
NAME      = "host_error"
STATE     = "ERROR"
REMOTE    = "no"
RESOURCE  = HOST
TYPE      = state

It is a known issue. As a workaround I am testing the hooks subsystem with absolute paths to the scripts for the remote hooks:

COMMAND = "/var/tmp/one/hooks/ft/host_error.rb"

Hope this helps.
