Force unmount of a SWAP filesystem left over from bad Live Upgrade

Hello,

Long story short, we built an alternate boot env. back in July and applied the latest CPU to about 15 servers. Of the 15 servers, 7 servers failed to start the zones after the luactivate / reboot. The zones failed to rename from <zone>-<boot_env> back to <zone>. This is fixed in patch 121430-95.

Anyway, we got that mess fixed up (or so we thought) but now I'm trying to apply the Oct CPU and running into an issue. I can build a new boot env. I can even apply-prereq but I cannot patch the BE.

It appears there is zone/lu mount that is causing me this problem.

Code:

# ./installpatchset -B Oct2017CPU --s10patchset
ERROR: Failed to determine zone configuration for target boot environment.

       Please ensure all LU boot environments are unmounted, and altroots other
       than the target altroot are unmounted prior to executing this script.

# df -h | grep -i swap | grep lu
swap                   309G     0K   309G     0%    /zoneroot/spahwfm1/lu

# umount /zoneroot/spahwfm1/lu
umount: /zoneroot/spahwfm1/lu busy

# fuser -cu /zoneroot/spahwfm1/lu
/zoneroot/spahwfm1/lu:

# umount -f /zoneroot/spahwfm1/lu
umount: Operation not supported
umount: cannot unmount /zoneroot/spahwfm1/lu

We rebooted one of the servers and the lu mount did not come back and than we can complete the installcluster / installpatchset.

Is there any way for me to force an unmount of this zone lu SWAP?

I don't think I'll be able to request that we reboot 6 production servers just to patch them and reboot them again.

HELP!

EDIT: Two things I want to mention, no, the /etc/zones/index does not list the global zone as configured instead of install (at global or in BE) and no I am not missing zone packages. I know this is related to the zone lu SWAP.
