Have been running and upgrading host+jail for years and through several
versions of FreeBSD. However, I got behind on updates and now playing
catchup on an important production server.
Tried to upgrade fbsd-7.0 --> 7.4 followed by upgarde of a jail as in
past. However, on reboot, the host booted up OK, but the jail would not
work. On re-trying to start the jail, only got a crytic error about
missing syscalls. I've never seen this before and don't have a clue what
needs fixing.
My setups for starting jails are in the /etc/rc.conf file and such still
works here in Texas on local servers when upgraded. However, the
production server is in Los Angeles and cannot react to any serious boot
problems without sending the ISP owner downtown to switch my HD back to
a bootable clone before the upgrade attempts. I cannot afford to have
the jail offline as it contains my SSL stuff vital to the business.
I manage the jails using the tools that came with Jail(8).
Can anyone point me in the right direction on this issue? Do I now need
stuff in sysctl.conf for the jail? Or.....????
Thanks for any help!!
Your mention of sysctl.conf makes me wonder: missing syscalls, or
missing sysctls? There was a change between 7.0 and 7.4 where some
jail-related sysctls were added.
There was also a change to the jail(2) system call, with a new version
of struct jail - but the old version continues to work. I don't think
there were and new syscalls at that point - perhaps other new sysctls?
Is the problem in actually creating the jail, or in processes that run
inside the jail? If the latter, there's really a lot of things that
could be the problem, if you're running an un-updated user space. Not
that they *should* happen, mind you, but still a lot more room for
something to go wrong.
