[zones-discuss] Re: Advice wanted - sharing file systems across multiple zones
Hi.. Hello, [...] dir. I have looked at delegating a dataset to samba and creating a new fs for each user but then I cannot share that with www. I also tried creating the fs under the global zone and mounting that via lofs but that did not seem to carry over each underlying fs and lost the quota capability. I cannot share via NFS since non global zones cannot mount from the same server. If you dont't want to use a commercial product to mount the smb share provided by the samba zone (such as sharity), I think your only chance is to share the zone's filesystem via NFS form the global zone. Either you have your zfs dataset just in the global zone and export it to both the samba and the www zone (i don't know if putting a samba share on top of a NFS share is a good idea), or you delegate the zfs pool to the samba zone and then export it from the global zone (like share /zones/zone-samba/root/data/smb if your zone-path ist /zones/zone-samb and your datadir is /data/smb). The more elegant solution in my opinion is the first one as zfs can share filesystems by setting just one parameter. You may have to look if there are any locking issues with samba on top of NFS, i think there were at least some with the Linux NFS implementation. If you choose soloution b, sharing a delegated dataset from the global zone, you have to be sure that all mounts are disconnected and you unshare the mount form the global zone before you shut down the samba zone. If you forget to do that, your samba zone won't come down. The only soloution I found to clear the zone was to reboot the whole box. Hope that helps, Joern This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] Mounting /var and /opt as filesystem in container
Brad, I am not sure what you are trying to achieve, but http://docs.sun.com/app/docs/doc/819-5461/6n7ht6qsm?a=view lists the ways that are possible, if you want to bring a global Zones ZFS into a zone 1. Look for Adding ZFS File Systems to a Non-Global Zone and please note the text in the comment after that ! 2. Another way would be to just create a loopback mount into a zone. e.g.: mount global-zone:/zoneshare in a zone as local-zone:/zoneshare in zonecfg: add fs set type=lofs set dir=/zoneshare set special=/zoneshare set options=rw I assume you mean 1., but 2. also works.

Nicolas Dorfsman wrote: Hi, Something is unclear in Solaris containers and Solaris ZFS docs Two extracts : http://docs.sun.com/app/docs/doc/819-5461/6n7ht6qsm?q=zonea=view Consider the following interactions when working with ZFS on a system with Solaris zones installed: A ZFS file system that is added to a non-global zone must have its mountpoint property set to legacy. A ZFS file system cannot serve as zone root because of issues with the Solaris upgrade process. Do not include any system-related software that is accessed by the patch or upgrade process in a ZFS file system that is delegated to a non-global zone. http://docs.sun.com/app/docs/doc/817-1592/6mhahuop2?a=view 4. Set the zone path, /export/home/my-zone in this procedure. zonecfg:my-zone set zonepath=/export/home/my-zone Do not place the zonepath on ZFS for this release. I can't understand why the upgrade process need to have non-global root zone on anything else than zfs. Does the boot cdrom can't mount ZFS volumes ? The installation software does not yet understand ZFS, and is not able to upgrade a Solaris 10 system with a ZFS root file system. Further, it is not able to upgrade a Solaris 10 system with a non-global zone that has a ZFS file system as its zonepath. -- -- Jeff VICTOR Sun Microsystemsjeff.victor @ sun.com OS AmbassadorSr. Technical Specialist Solaris 10 Zones FAQ:http://www.opensolaris.org/os/community/zones/faq -- ___ zones-discuss mailing list zones-discuss@opensolaris.org

I also tried creating the fs under the global zone and mounting that via lofs but that did not seem to carry over each underlying fs and lost the quota capability. What file system type are you using? Delegating a dataset implies ZFS, but all of the common file system types can be mounted into a zone using LOFS. What behavior did you see regarding the loss of quotas? If ZFS quotas are not maintained when mounted via LOFS, is it possible to use UFS instead? Is there a reason that you cannot mount the underlying file systems into the zones as well? I cannot share via NFS since non global zones cannot mount from the same server. How can I achieve what I want to do? Perhaps there is another method to achieve your real goal(s). In non-technical terms, what is your goal? In other words, why do you want one zone to serve files to another zone?

Re: [zones-discuss] Mounting /var and /opt as filesystem in container
Hello Detlef, What I want to do is add a new non-gobal zone where the initial zone config includes a legacy mode zfs filesystem. If the zfs filesystem exists but is not mounted, when you install the zone, you get an error similar to the following: Preparing to install zone m1. ERROR: No such file or directory: cannot mount /data/zones/m1/root/zfstest in non-global zone to install: the source block device or directory backup/zfstest cannot be accessed ERROR: cannot setup zone m1 inherited and configured file systems ERROR: cannot setup zone m1 file systems inherited and configured from the global zone ERROR: cannot create zone boot environment m1 zoneadm: zone 'm1': '/usr/lib/lu/lucreatezone' failed with exit code 74. Error: Zone installation failed, return value: 0 I want to know if there are specific steps that I can incorporate into my zonemgr script to enable this without having to wait until the zone is created and add the zfs filesystem as a second step.
