How to use the pool for graylog

[da_da]

Looks like when you install the graylog in the jails, it uses the the jails to store the data. How does one make this happen?

I tried to create a dataset graylog on the pool and create acls for elasticsearch/Mondo/Graylog however, it seems that I am unable to startup elasticsearch.

I have the mount point to /mnt/graylog... but no go...
