Can't start Jail due to ifconfig: ioctl (SIOCAIFADDR): File exists

[tobybryans]

I had to increase storage on a FreeBSD 14.1 VM last night which needs a powerdown. When I bought it up again one of my Bastille jails refused to come up with the following error:

[spamd]:
ifconfig: ioctl (SIOCAIFADDR): File exists
jail: spamd: /sbin/ifconfig bastille0 inet 10.13.0.8 netmask 255.255.255.255 alias: failed

All other jails started fine. I tried manually staring and stopping, but it still wouldn't come up with the same error.

I destroyed the jail, tried to recreate it and the same thing happened on jail creation.

I recreated it on another IP (10.13.0.25) and it worked fine.

an ifconfig returns the following:

ifconfig bastille0

        groups: lo
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

and 10.13.0.8 is not on that list (or on any other interfaces).

I am at a bit of a loss of how to debug this further, so any advice would be greatly appreciated, and I fully understand that this may not be a Bastille issue, so if that is the case happy to take the ticket elsewhere.

@cedwards any ideas on what hung him up????

At the beginning of the "start.sh" and "stop.sh" files, add "set -x" to enable debug mode. Then run the commands again and you can see what it is hanging on.
