Hi,

I have just observed the following issue and I would like to ask if it is already known:

I'm using zones on ZFS filesystems which were cloned from a common template (which is itself an original filesystem). A couple of weeks ago, I did a pkg image-update, so all zone roots got cloned again and the new zone roots got promoted. I then decided to undo the update and promoted the original zone roots again.

So until today, the zone template was dependend upon one of the zone roots and when I promoted it again to restore the intended order, all zones effectively crashed. When trying to execute processes in them, I got exec failures like this one:

# zlogin ZONE
[Connected to zone 'ZONE' pts/2]
zlogin: exec failure: I/O error

Is this issue known to anyone already?

Thank you, Nils
