iocage jails fail to start at boot in 11.1-U4

[Paul van der Zwan]

Hi,
I just upgraded to 11.1-U4 ( from -U3) and iocage jails still seem to be very tricky.

After boot I need to create bridge0 manually and attach my lagg0 to it to get the bridge up and running.

But trying to start the iocage service I get a Read-only file system error, probably same error scrolls by when booting, and is shown when I run 'iocage list -t':

Code:

root@freenas:~ # service iocage start
* [I|O|C] starting jails...

OSError: [Errno 30] Read-only file system: '/mnt/iocage/templates/template-20180224/tmp40ucr6bh'

Starting each jail individually one at a time does seem to work.

Best regards,
Paul

This may already be resolved with the newer iocage in the nightlies (if you have a system to test). If you still get this error after 11.2-BETA1 is out in a few weeks, please create a report at bugs.freenas.org and post the issue number here.
