fuser -k /media/nss/GWDOM
seems to also unload ndsd (eDirectory) when its on a NSS file system.
Use this instead:
pkill -fx "/opt/novell/groupwise/agents/bin/gwmta @/media/nss/GWDOM/groupwise/agents/share/gwdom.mta"
You can find the text that goes in between the quotes by using this command
ps aux | grep gwmta
I hate that we are doing this kill in the first place.
