[request-sponsor] Bug 6284623
As a first stab at contributing code to OpenSolaris, I would like to work on bug 6284623. When I first encountered this bug, I opened a case and 6297127 was opened on my behalf. http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6297127 shows pretty clearly where the problem lies. I have succesfully built the current ON source (only 9 hours on an Ultra 2!) and my initial stab at the fix seems to build and run without any warnings or errors. I have not yet submitted the contributor agreement but should have that in shortly. Mike -- Mike Gerdts http://mgerdts.blogspot.com/ -- next part -- An HTML attachment was scrubbed...

[request-sponsor] RFE - zoneadm clone should use zfs snapshot/clone
I opened an RFE related to this earlier today, but I have not received any indication what the RFE number is. Here is a what the RFE says: zoneadm clone is a great feature However, it could be faster and more space efficient if it were to bring in the zfs feature set. Currently the command zoneadm -z target clone template performs a find | cpio to copy the data. However, it would be much more time, space, and performance efficient for it to have a zfsclone method. The general algorithm for the new copy_zone_zfs() would be: zfs snapshot fs mounted at zonepath of source_zone@zone-SUNWzone-newzone zfs clone snapshot from above pool/SUNWzone-newzone zfs setmountpoint=zonepath of newzone pool/SUNWzone-newzone Presumably the zfs commands above would really be implemented through the zfs API. I have implemented what I describe above, using the appropriate calls to libzfs. Here is a zone creation in less than 1 second on an Ultra 2: # time ksh -x /var/tmp/clone + newzone=fast + template=template + zoneadm=/ws/usr/src/cmd/zoneadm/zoneadm + PATH=/usr/bin:/usr/sbin + zonecfg -z fast create -t template + zonecfg -z fast set zonepath=/zones/fast + /ws/usr/src/cmd/zoneadm/zoneadm -z fast clone -m zfsclone template Cloning zonepath /zones/template... real0m0.922s user0m0.128s sys 0m0.171s I have a little bit of cleaning before it is ready for others. Also, I would like to get zoneadm uninstall to be smart enough to just destory the clone and snapshot if it was created with this mechanism.

[request-sponsor] RFE - zoneadm clone should use zfs snapshot/clone
Mike, There is already an RFE open for this: 6383119 RFE: add support for using zfs clones when cloning a zone and we are in the middle of active development on this feature already. The code we have will automatically create zfs filesystems when you install new zones, will destroy the zfs filesystem when you uninstall the zone and will automatically clone the zone using the appropriate technique based upon the source and target filesystems. We'll be starting the architectural review process for these new features shortly. Once those have been approved by the ARC process, the code should be available within the open solaris source tree. If you are interested, we can take this over to the zones-interest alias for further discussion. Maybe you would be interested in taking a look at the code we already have and seeing how it fits with what you have been doing.
