Any idea on how to get zfs in the jail? I have been told I had to add the devfs rules for zfs. Yes, I've told you what you should to do. First part you have been done already -- you've edited /etc/devfs.rules and added new configuration subsection with instructions to unhide /etc/zfs. Please do the second part: instruct the /etc/rc.d/jail to apply these rules to DEVFS instance mounted into your jail. Just change 'devfs_system_ruleset' to 'jail_batman_devfs_ruleset' and restart your jail -- /etc/rc.d/jail does NOT pay attention to system-wide DEVFS ruleset variables, it uses per-jail ones. If you have configured all the things correctly, you MUST see /path/to/root/of/your/jail/dev/zfs :) -- Andrew. Hi Andrew, this is working. Thanks. THe only problem is that after every reboot I have to rerun the following commands to get things working again. hulk# zfs jail 4 zfspublic/batman batman# zfs mount -a If I don't do the jail 4 command the command batman# zfs get all does not return anything. Seems like the zfs jail 4 command is not remembered. The zfs manpage does not tell of where to store these settings.

ZFS in a jail
Hi all, I want to access a zfs dataset from within a jail. When following the instructions on the various pages I get stuck. I am running: FreeBSD hulk.superhero.nl 7.0-BETA3 FreeBSD 7.0-BETA3 #1: Fri Nov 30 19:13:07 CET 2007 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/GENERIC amd64 Jails are set up as detailed in http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html. With ro mount for system files created by buildworld and a rw mount for the various directories which require to be read/write such as /usr/local, /var, /home and /etc. I am following the steps as outlined in: http://blogs.freebsdish.org/pjd/2007/03/. I don't have any problems with creating the zpool and the zfs dataset on the host but when I try to create in the jail I get the following error. batman# zfs create public/jail/public internal error: failed to initialize ZFS library In /var/log/messages on the host I get the following: Dec 2 21:47:01 hulk kernel: WARNING pid 36752 (zfs): ioctl sign-extension ioctl cef85a2b I do have the 2 sysctl settings set. Even running zfs gives me a problem within the jail. Some help would be much appreciated.

Which is good in a way in that it is not completely defeating common sense, but means I shall go and look elsewhere for the problem. What kind or Array Controller do you have? Does it has a batterypack and how much cache? How is the logical array configured with regards to read/write cache?
