[zones-discuss] Re: Re: Question: Zones/Mpxio + Disk Array (HDS 9970V
Doug, Jeff and all the rest of you guys, Thanks a bunch for all the answers!!! After your answers and a lot of reading this weekend i have some thoughts on where to start. Since i need to 'create and export' a ZFS filesystem from a Disk Array, here's what i will try to do: 1, Make the file system [around 110Gb] [b](/export/home/ftp)[/b] for my ZONE1 (an Anon FTP Server) in the Global Zone. 2, [b]'Delegate Datasets to an Non-Global Zone'[/b] as described in the [b]'Containers'[/b] Guide. This way the file system area for the Anon FTP Server will be 'local'. 3, This goes for all of my '3' Zones that i will create. I would like to be able to mount any DISK POOL from the Array and to have the ability to [b]grow[/b] the filesystems during normal hours since we are hosting the better part of the world here. One of my problems is to understand how the access to the Disk Array (HDS 9970V) is being handled by the Non-Global Zone i.e. 'Anon FTP Server' in regards to the Global Zone where HBA Support is part of the Solaris 10. Where is the Access and HBA support handled to the ZONE's ? Transparently ? Regards, Pierre This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org

This way the file system area for the Anon FTP Server will be 'local'. Why do you want to use a delegated dataset instead of a filesystem? It would be very simple to mount a global zone filesystem into the non-global zone using a LOFS mount. 3, This goes for all of my '3' Zones that i will create. I would like to be able to mount any DISK POOL from the Array and to have the ability to [b]grow[/b] the filesystems during normal hours since we are hosting the better part of the world here. Do you want to grow the filesystem while logged in to the global zone, or non-global zone? One of my problems is to understand how the access to the Disk Array (HDS 9970V) is being handled by the Non-Global Zone i.e. 'Anon FTP Server' in regards to the Global Zone where HBA Support is part of the Solaris 10. Where is the Access and HBA support handled to the ZONE's ? Transparently ? If you mount the filesystems in the global zone, and then use LOFS mounts into the non-global zone, everything is handled transparently. The processes in the non-global zone 'see' a normal filesystem. -- 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

Something like $ zfs create mypool/export/zones/zone1 $ mkdir -p /export/zones/zone1 $ zfs set mountpoint=/export/zones/zone1 mypool/export/zones/zone1 With zonecfg set your zonepath=/export/zones/zone1 Wait a sec, this doc is pretty unequivocal about doing this: http://docs.sun.com/app/docs/doc/817-1592/6mhahuous?a= view Hmmm, I have been doing this for a long time (though on nevada) with no problems. If this document is correct it looks like Sun has shot itself in the foot and released ZFS to Solaris 10 with a zery large bug. Is UFS safe???

For some reason the url provided does not seem to bring up any specific section in the doc for me, so I am not sure which section is being referenced. Although you can put a zone on a zfs filesystem, we currently caution against this because the upgrade support is not available yet. If you do this on S10u2, you won't be able to upgrade to S10u3. There is also an issue with how space is calculated for installing patches when the zone is on zfs. We have this on the list of things to work on, but I am not sure when it will finally be done. In the meantime, you have to be careful about this kind of configuration. We do have code already available in opensolaris which will automatically create this kind of configuration. It has not yet be backported to S10 because of the these issues though. I am not sure what the comment about 'ufs not being safe' means.
