How do I share non-global zone filesystem?

I have a non-global zone that needs to have a UFS local filesystem. That file system also needs to be accessible (via NFS or whatever) to another non-global zone.
Can this be done?

I have a non-global zone that needs to have a UFS
local filesystem. That file system also needs tobe
accessible (via NFS or whatever) to another
non-global zone.
Can this be done?Not directly by the non-global zone. You can't
currently serve NFS from them.
However, could you host the filesystem in the global
zone, then have both of the non-global zones access
it as a loopback filesystem?
DarrenOne of the non-global zones needs to write memory mapped files to the filesystem.
All zones need read/wite access.
Is it legit to have multiple zones having read/write access to a loopback filesystem?

Can I import one non-global zone from one machine to another?

If create a non-global zone on one disk on machine A, is it possible to make a copy of that disk, and import the non-global zone to machine B? If yes, how to import the non-global zone?
Thanks!

It should be possible if your machines are installed at the same way, because you need the same environment (patches, packages,..).
If this is true you should export your zone definition on machine A (zonecfg export) and import it on machine B (zonecfg -f ...).
Then create the new zone on B. If finished get your zonepath with all data on A an copy it to B. That should be all.
With this solution I hope it would be possible to have a shadow instance on B and the aktiv instance on A. If you have your whole zonepath on external disks like EMC, you only have to mount your disks on B and start your zone.

How can 2 non-global zones share a singe ethernet?

This may be a very basic question. I am new the this board and trying to learn more about the Solaris Zone.
I am trying to find out whether sharing an ethernet card between two non-global zones is possible.
Where can I get additional infor on this topic?
Thanks,

I just found the answer to my question. Thanks, Can you post a link to where you found the answer?
Birdman >>I'm not exactly sure what he found, but you might try this link, to the zones documentation:
http://docs.sun.com/db/doc/817-1592/6mhahuos1?a=view#z.admin.ov-12
The answer to the question is "yes" you can do this, and in fact it is somewhat trivial. We've long had a feature in Solaris called "logical network interfaces". This allows multiple logical interfaces to be defined atop a single physical one. Zones uses this feature and creates logical interfaces atop a single virtual interface. You can even have multiple network interfaces assigned to the same zone, without any problem.

How to install JDK6 and Netbeans 6 in a non-global zone?

Hi,
I have a Solaris system where I want to deploy separate containers for several developers.
I'm having difficulty in installing JDK 6 and Netbeans 6, I get lots of missing package errors in non-global zone.
What would be the best approach for installing jdk 6 + netbeans 6 seperately for each developer?
Thanks in advance.

Hi
It depends how you have created your zone, what has been inherited from the global:
inherit-pkg-dir:
dir: /lib
inherit-pkg-dir:
dir: /platform
inherit-pkg-dir:
dir: /sbin
inherit-pkg-dir:
dir: /usr
But if you only want a jdk and netbeans, there is no really dependencies the simplest approach si to download the not packaged version and put it in /opt which is not inherited
You just have to put a jdk in /opt/jdk1.6.0... and netbeans in /opt/netbeans-6.0..
Don't really understand why you want a separate zone, one zone, several accounts which share the same jdk and netbeans, that's the way unix work ;)

Why I "Cannot share fielsytems in non-global zones"?

Dear all,
I've succesfully configured a solaris zone (which for the pourpouse I've called "stefano" just as a test) perfeclty running.
I've just a problem while I'm trying to export a directory as command
share -F nfs -d "test" /export/home/stefano
if run inside the zone gets me this error:
share_nfs: Cannot share filesystems in non-global zones: /export/home/stefano
why it isn't possible to export a filesystem within a non-global zones?
Is there any trics to solve this issue?
Thanks for your attention, ciao everybody!

I don't want to mount an NFS filesystem exported from the global zone
I want instead to share an NFS filesystem within a non-global zone in order to let it mount by some others machine.It simply can't be done today.
NFS interacts very tightly with the kernel. So enabling an NFS server means giving certain kernel level permissions. The simple way to let a non-global zone do this would break the security model of zones. I'm sure folks are working on other ways to do this, but it's not available at this time.
Non-global zones aren't allowed to do everything. This is one of the things they're not allowed to do.
The global zone can share a non-global-zone's data to let other machines mount it. But you need global zone privileges to make that occur. The non-global zone's administrator couldn't do it directly.

How to retrieve # on-line procs in a non-global zone with resource pool

Is there any way to retrieve the #of on line processors of the machine running in a non global zone with resource pool ?
sysconf does not return this value. In fact this is an excerpt of the man:
"If the caller is in a non-global zone and the pools facility is active, sysconf(_SC_NPROCESSORS_CONF) and sysconf_SC_NPROCESSORS_ONLN) return the number of processors in the processor set of the pool to which the zone is bound."

So, from within a local zone that's in a pool (i.e. in a pool with 8 CPUs) , you want to query how many CPUs really exist in the global zone (i.e. the global zone may actually have 16 CPUs)? I don't think that's possible: in fact for security reasons it's probably intentionally disabled.
A quick workaround would be a script/cron-job in the global zone that writes a small file in the filesystem of the local zone... then from within that zone you could read the CPU count.
I'm interested though: what are you trying to set up?

Non-Global Zones - how can I tell what the Global Zone is

Hi,
I have a host that I know is a non-global zone (ngz). I can ssh to the ngz as root or a non-privileged user.
But once there how do I know what the host name for the global zone is?
I could probably run a script from all global zones to report all running zones and so I'd know that way but I have a specific need to know from inside the ngz.
Thanks!

That's a built-in security feature; and I know of no way to circumvent this mechanism.
I had some hope that there was a way to 'see' at least the global-zone information from the zone. From the shell the 'zone' commands are available ..
:# zoneadm list -cv
ID NAME STATUS PATH
48 hostname_svn running / So it's at least aware that it is a zone, even if it can't tell me anything else about itself. I can still go the long way around to get the information for my need, thanks.
The global zone is the only thing that can see everything. The non-global zones can only see information specific to their zone.
This is by design and it really is a security mechanism. You don't want the zones running outside of their boundaries and information about the global zone (or any other zone) is outside the boundaries of a non-global zone.

How to enable GUI in a non global zone in solaris11?

How to enable graphical logon in a non global zone in solaris11, so the zone can be login by Xmanager? Thanks!

This guide will cover how to setup a basic VNC connection to a Solaris 11 machine. There is also an optional step to allow for persistent VNC connections.
Step 1
Configure GDM to include ‘[security] DisallowTCP=false’ and ‘[xdmcp] Enable=true’.
$ sudo gedit /etc/gdm/custom.conf
# GDM configuration storage
[daemon]
[security]
DisallowTCP=false
[xdmcp]
Enable=true
[greeter]
[chooser]
[debug]
Step 2
Configure X-Server to accept remote connections.
# svccfg -s application/x11/x11-server
svc:/application/x11/x11-server> setprop options/tcp_listen = boolean: true
svc:/application/x11/x11-server> end
Step 3
Configure the VNC service (you could change the ‘-geometry 1280×720′ to whatever resolution you would like).
# svccfg -s xvnc-inetd
svc:/application/x11/xvnc-inetd> setprop inetd_start/exec = astring: "/usr/bin/Xvnc -desktop sol11:0 -geometry 1024x768 -inetd -query localhost -once securitytypes=none"
svc:/application/x11/xvnc-inetd> setprop inetd/wait = boolean: true
svc:/application/x11/xvnc-inetd> end
** The line highlighted red is optional – only do this if you want your VNC connection to persist (as well as any potential security issues)
or
# svccfg -s xvnc-inetd
svc:/application/x11/xvnc-inetd> editprop
search for # setprop inetd_start/exec = astring: "/usr/bin/Xvnc
copy the line, uncomment the copy, makethe changes above, write the file out.
svcadm refresh xvnc-inetd
Step 4
Disable and the re-enable the GDM and VNC-inetd services for the changes to take effect.
$ su root
Password:
# svcadm disable gdm xvnc-inetd; svcadm enable gdm xvnc-inetd
If still in maintenance, reboot (I had to, don't know why).
Step 5
Point your favourite VNC client at your Solaris server and test if it accepts your VNC connection – you should be presented with a Username/Password login screen.
If you performed the optional step to make your connections persist – close your favourite VNC client and then reconnect – if you remained logged in you have a persistent connections.
Greg on said:
After a fresh text install of Solaris-11 (11/11) both xvnc-inetd and gdm are not present. After installing them (# pkg install xvnc-inetd gdm) I can’t get gdm to start:
# svcadm enable gdm
# svcs gdm
offline 10:24:03 svc:/application/graphical-login/gdm:default
Any thoughts?

You are missing some X packages. Do the following:
pkg install slim_install           # installs 400+ packages
svcadm enable gdm && exit      # gdm now works
pkg uninstall slim_install           # uninstalls the installer package only

How to know global zone in case non global zone is hung

....I have nongloabazone1,nongloabazone1,nongloabazone2,nongloabazone3...
i am working on nongloabazone1 ..
suppose i am giving remote support ...
if my nongloabazone1 is hung ..i need to know the global zone on which this nongloabazone1 is installed and reboot from there ...if my nongloabazone1 is hung i cannot apply #arp -a and check it out by trial and error method and know the global zone....
in this case how can i reboot the nongloabazone1 .....i have the same question in case of Ldoms also..............
Thanks in Advance.......

Hi.
It's not clear what means "non global zone is hung".
In case it realy hangs you can't do anythins in this zone.
1) In case you have access to global zone. You can get list all zones running on this host:
zoneadm list -cv
For reboot local zone from global zone just need: zoneadm -z <zone_name> reboot
2) Zones not support live migration. So after zone started it can not change global zone.
Create script that put global zone name in file. When need - just read content of this file.
This file can be created from global zone when start (or create/move) local zone.
In case zone migration is not quickly operation, just create file (or database) for list what zone started on which host.
For LDOM it look wery same.
Regards.

How to add a second nic card to non global zone

hi every one
i have a issue like
my non global zone has hme0 as the nic card
i want to add a secondary nic card like pcn0 to the non global zone . how can i add to the nonglobal zone so that both the nic cards should exist in the nonglobal zone
please tell me the command and procedure for that
thanks in advance ....

If your non-global zone is a shared IP zone, then you can add like
zonecfg -z <zonename>
add net
set physical=pnc0
set address=<IP Address>
end
verify
commit
exit
If your non-global zone is an exclusive IP zone, then remember that the interface pnc0 you are adding will be in control of non-global zone exclusively.
Steps to add it are same as above.

How to install a SUN cluster in a non-global zone?

How do I install a SUN cluster in a non-global zone? If it is the same as installing SUN Cluster in the global zone, then how do I access the cdrom from a non-global zone to the global zone?
Please point me to some docs or urls if there are any. Thanks in advance!

You don't really install the cluster software on zones. You have to set up a zone cluster once you have configured the Global Zone cluster (or in other words, clustered the physical systems + OS).

How to create a separate /var partition on solaris non-global zone

Hi
I found no simple way to create a separate /var partition in solaris non-global zone.
I am using solaris 10 u9 and my root pool is zfs. My zone's zonepath is also separate zfs fs.
But, I do not know how to make the /var as a mountpoint of another zfs dataset since /var is not empty.
I also do not know if there is a way to install a zone with /var as a separate (outside '/') partition.
That will be really useful.
Any suggestion?
Thanks
Edited by: vadud3 on Sep 20, 2010 12:16 PM

I meant a separate zfs fs with mountpoint '/var' in a non-global zone.
I am insisting, because I do not want /var to fill up the '/' on non-global zone.
With default non-global zone installation, you cannot avoid that.
My zonepath itself is a zfs fs. I also have a zfs dataset provisioned to the non-global zone.
I cannot create a zfs fs out of that dataset and mount it as '/var' becasue by then non-global zone
already installed content on '/var'
I want the '/var' as a separate dir or mountpoint, the same reason global zone gives you that option during install.
Thanks
