We have Solaris11 Express server with Zones A Zone delegated ZFS dataset is not remounted after Zone or Server reboot. (mountpoint property is set on ZFS dataset) What can be missing in ZFS or Zone configuration ?
I would check the logs for svc:/system/filesystem/local:default inside the zone, which should be /var/svc/log/system-filesystem-local:default.log (verify with 'svcs -l filesystem/local'). It might be some sort of conflict with the mountpoint (directory not empty or some such). Any output from an attempt to mount that filesystem should be in the log.
