We changed the ZONEPATH to reflect the new zonename and the IP as

Here is the ERROR they get: could not verify fs /usr/localcw: could

Now, I understand adding this step (mkdir -p
/zones/roots/bluto-zone2/localcw), before running the zoneadm -z
bluto-zone2 clone bluto-clone1) will allow the clone to work, but it
kind of defeats the purpose of the word CLONE. Clone to me for
example means whatever I have in this zone clone it, and I should
have a identical new zone with the same stuff just a new hostname and
IP. I shouldn't have to make the directory first in the ZONEPATH for
it to work. I would think the /zoneadm/ with the /clone/ option
should be smart enough to see that the directory
/zones/roots/bluto-zone2/localcw doesn't existed and create it since
I'm telling it to create the zone with theses identical attributes
from the bluto-zone1.
If a customer has 50 lofs filesystems in the origainal zone, do we
mean they would need to run the mkdir command 50 times. That's just
Am I missing something!! Or is this the way it's supposed to work for
now and it will be future releases
If I understand what your customer did, then I think you left out
a step above. You said they changed their zonepath and IP address for
the new host. However, based on the names above, it also looks like
they changed the lofs mounted filesystem configuration for the new zone.
This is reflected on line 18 of the configuration listing above. If
this is the case, then the two zones do not have the same filesystem
The two zones do have the same configuration. The same lofs filesystem.
That is my point. unless I physically make the directory structure as
shown with mkdir -p /zones/roots/bluto-zone2/localcw the clone fails.
Personally I think that's not right. Personally cloning to me, means
whatever I have in X, I want th same in Y. As I mention if I have 50
zones identical configurations and before I can clone the 50 zones I
need to do a mkdir, to create those filesystems, then cloning, in my
opinion doesn't work.
The purpose of the zoneadm clone command is to use the original zone's
installation as the basis for the new zone. With cloning, the new
have the exact same filesystem contents as are on the original zone.
change the filesystem configuration for the second zone, then that
basically no longer makes sense. All that the clone command does is
the original zones contents within the new zone. It does not attempt
out that you made changes to the configuration and that it should
those changes with what was in the original zone.
There is a fundamental misunderstanding in your explanation above.
clone command *does not* create the zone. You have already created the
zone using the zonecfg command. The zoneadm clone command is an
way to install the zone using the bits from another zone as the basis
installation. If the two zones are not configured the same, then a clone
installation generally cannot work.
Now, as you noted above, you can workaround this for this specific case
by creating the new filesystem that needs to be lofs mounted. This works
since the lofs mounted data is not actually cloned during the
The point here is that the clone command does not create any filesystems
that are needed for your zone configuration. It simply replicates the
data from the first zone into the second zone. So, the bottom line is
yes, you must manually create any filesystems that you need to have lofs
mounted into the zone. There is no zone commands that will do that
In fact, you will have the same problem if you tried to just install the
zone (as opposed to cloning) since the filesystems needed for the zone
lofs mounts don't exist until you create them.
Thanks for responding Jerry!! I appreciate it.
