Thank you for your response. I tried setting it up like that (use zfs
set jailed=on), and that did not work. I could not even run zfs from
within the jail. Maybe I did something wrong -- so I am setting up a
test box where I can try them all out.
You need to have the zfs device visible in the jail, for this you need
to use a devfs rule at jail-start which makes it visible in the jail.
See http://www.leidinger.net/blog/2011/05/19/how-i-setup-a-jail-host
in the part "Additional devfs rules for Jails"
(devfsrules_jail_withzfs).
Bye,
Alexander.
Dear Miroslav, Alexander
Thank you both for the pointers. As soon as the test machine finishes
compiling the world (I am using vimage, need custom kernel), I will give
that a try.
However, I did set up the things Miroslav suggested, along with tweaking
the sysctl variables for jail zfs mount, and also setting the zfs
jailed=on -- but on the existing system that had no effect whatsoever
(even after a restart). So, I am thinking this might be due to the fact
that all jails are nullfs mounted, hence the test box.
I will update once I get the chance to play with the information you two
kindly provided and let you know how it goes.
Thanks and regards
SK
