I'm trying to set up a software striped raid configuration on a mac mini 2011 running lion server. The procedure seemed to be pretty straight forward, but the result was far from the expected. Here's the tutorial I followed step by step:
run these 2 commands in terminal to use debug mode in disk utility:
defaults write com.apple.DiskUtility advanced-image-options -bool truedefaults write com.apple.DiskUtility DUDebugMenuEnabled -bool truestart disk utility, go to debug menu and select "Show every partition".
clone/restore the Recovery HD volume (650MB) and Macintosh HD (lion) volume to an external drive (2 separate partitions). boot the mini holding option key and choose the recovery partition on the external drive.
once booted into recovery, start disk utility. and format the mini internal drives to striped raid set. should be fairly quick to set up. once the raid set is mounted, clone the Macintosh HD partition from the external drive to the 1TB raid volume. reboot mini holding option key and choose the raid volume.
if it doesn't boot up properly, then boot mini again from Recovery HD partition on the external drive and do a fresh install of lion onto the raid volume. it will then download approximately 4GB of lion install files from apple's server and install it to the raid volume. should take about an hour and you may not see the progress meter move for several minutes, but don't touch it til it finishes.
I did exactly as told until the part where we restore both partitions from the mac mini's original setup into the external drive. I created the raid set using disk utility from the recovery partition on the external drive, but when I tried to restore the Server HD (from backup) into the raid set, it fails with an error:
error 32 - broken pipe
I've heard about this broken pipe error affecting newly created partition for bootcamp installs. It basically means that the partition is seen as non active. I tried to run fdisk from terminal, but when I do
fdisk /dev/disk2
it says "permission denied".
I also tried to restore the old system into the raid set using superduper. It successfully loads all data into the raid disk, but it does not boot (with a weird "no parking" sign over the tray background I had never seen before). I'm at the point where I'd take this failed restored disk and reinstall lion on top of it, but since it takes so long to download lion's recovery stuff, I thought I should ask here before.
Apple's discussions are sooo slow... Hope anyone could help me.
Best regards,
