zpool not working in jail

[Semus]

Please tell me how you can install the docker in the yail (freeNAS 9,10). I have a lot of containers that need to be placed in this jail. I made a jail. I'm root. I enter the following commands:

Code:

# pkg install docker-freebsd ca_root_nss
# dd if=/dev/zero of=/usr/local/dockerfs bs=1024K count=4000
# zpool create -f pool /usr/local/dockerfs

Reply:

Code:

cannot create 'pool': permission denied

Why "permission denied"? How to fix it?

I think you want to create a dataset using Volume Manager then Add Storage in the jail that points that dataset to /usr/local/dockerfs.

 

[Semus]

Yes. I want that in JAIL there will be a device of "pool"
Then I execute the command:

Code:

zfs create -o mountpoint=/usr/docker zroot/docker

And mount the device. How can I get rid of the problem with permissions?

Which how-to are you following? I'm pretty sure you instead have to make a dataset (or perhaps a zvol) in Volume Manager and point a storage to it...

how-to is here http://www.freenas.org/blog/docker-done-right/
Docker don't accept dataset mounted to /usr/docker with error
level=fatal msg="Error starting daemon: error initializing graphdriver: Failed to find zfs dataset mounted on '/usr/docker' in /proc/mounts"
