[OmniOS-discuss] Continuing hung-zone problems

[Bob Friesenhahn]

Previously I reported a problem (in the 040 timeframe) in that zones 
are hanging when being shut down.  Problems continue on that system. 
Today I am seeing the same issue with a different OmniOS system 
(version is omnios-r151020-4151d05).

In this case it was after doing 'init 6' to reboot the system and the 
problem added about 180 seconds to the shutdown time.  In three 
reboots, the problem happened twice.

This is logged:

Apr  2 17:50:13 velma zoneadmd[653]: [ID 702911 daemon.error] [zone 'swdev'] failed to open console master: Device busy
Apr  2 17:50:13 velma zoneadmd[653]: [ID 702911 daemon.error] [zone 'swdev'] WARNING: could not open master side of zone console for swdev to release slave handle: Device busy

Apr  2 17:51:53 velma svc.startd[10]: [ID 122153 daemon.warning] svc:/system/zones:default: Method or service exit timed out.  Killing contract 169.
Apr  2 17:51:53 velma svc.startd[10]: [ID 636263 daemon.warning] svc:/system/zones:default: Method "/lib/svc/method/svc-zones stop" failed due to signal KILL.

And this is the zone configuration:

create -b
set zonepath=/zones/swdev
set brand=lipkg
set autoboot=true
set limitpriv=default,dtrace_proc,dtrace_user
set ip-type=exclusive
add fs
set dir=/scratch
set special=/scratch
set type=lofs
end
add net
set physical=swdev0
end

The zone does not use any particular resources, although it does act 
as a NFS client (via automounter).  The NFS should not have been 
mounted at the time.

Any ideas?
