To my surprise the datasets that I had shared previously were still shared. Process: # This command adds the share through nfs in /etc/zfs/exports zfs set sharenfs='-maproot=0 disbatch' exports/svn bla bla bla after using them for a little while: # This command should turn off the nfs share and remove the line from # /etc/zfs/exports and signal mountd or whatever. zfs set sharenfs=off exports/svn Low and behold this line is never removed the share and continues even through a reboot all while sharenfs=off on the dataset. No no other datasets are shared at this time. The line in /etc/zfs/exports changes just fine when changing the options via "zfs set sharenfs". I also removed /etc/zfs/exports and repeated the process. It still continued. Also have destroyed datasets and the nfs share still exists. Can someone take a look at this ?. >How-To-Repeat: # This command adds the nfs share in /etc/zfs/exports zfs set sharenfs='-maproot=0 disbatch' exports/svn # This command should turn off the nfs share and remove the line from # /etc/zfs/exports and signal mountd or whatever. zfs set sharenfs=off exports/svn >Fix: No known fix available at the moment. It does not look like fsunshare() is being called from the little time that I actually had to debug this problem before the report. >Release-Note: >Audit-Trail: >Unformatted:
