Not sure if this is correct, but i have now installed freebsd 10 on top of ZFS with jails and have created a jail for Mongodb.
For the data files I used the following:
zfs create -o atime=off \ -o compression=lz4 \ -o exec=off \ -o setuid=off \ -o checksum=off \ -o recordsize=8K \ -o mountpoint=/data zroot/data
When I launch my jail as:
ezjail-admin console db
data directory is not available
what am i missing?
