mdmfs in a jail

Hello all

I am trying to make a memory disk for my dansguardian server to store the ipc files
My proxy (dansguardian) server runs in a jail.

if i do
mdmfs -s 128m md /usr/memdisk
i get the following error
mdmfs: mdconfig (attach) exited with error code 1

What am i doing wrong.
Do i need some sysctl set?

Do i need to create the memory disk on the host itself
and mount it from there?

It's wiser to make it on the host. I'm not sure if it is allowed in a jail or not, I would expect it to fail on the mount part. The error you're seeing is probably caused by /dev/md* being hidden by jail_${name}_devfs_rules.
