OS X Lion Server

[rob_potvin]

Had some weird issues upgrading my mac mini server to lion. Wouldn't upgrade and would spit out error that it couldn't continue because the hardware didn't support a recovery partition. (It's mac mini server, RAID 1 is the configuration, it gave me that working when I started the upgrade process)

Anyway tried a couple of times and the error wouldn't go away. I then unplugged the time machine backup drive and it all went well. No more issues or errors.

So if any of you out there tempt the upgrade, make sure your time machine disk is unplugged.

Cheers

I seem to remember reading, although I can't find out where, that installing Lion on a software RAID 1 mirror is either problematic or unsupported. On Jul 25, 2011, at 3:19 AM, Rob wrote:

Do you have a recovery partition now? diskutil list should show it. Probably not relevant for a server, but for a client machine, no recovery partition = can't use FV2. Some Boot Camp-partitioned volumes also have issues with the Recovery partition being created.

This KB describes a potential work-around...

What to do if the installer warns that no Recovery HD can be created
Some disk partition configurations may result in the OS X Lion installer reporting that it could not create a Recovery HD. In these situations, even if you are permitted to continue the install, you should quit the install and create an external, bootable OS X Lion hard drive with a Recovery HD, first. You will be able to return to the upgrade to OS X Lion on your computer's boot drive after creating the external Recovery HD.
