Anyway to setup lion recovery partion on a raid?

Arcstorm · 05-24-2012, 03:35 AM

I am using a dual SSD Raid 0 setup on my macbook pro and do not understand why apple can't manage to allow a lion recovery partition on a raid setup. It's just another partition ...this seems really lame on their part. Can anyone explain why it is this way or if there is some work around to get one setup?

No there is not, it is a limitation that you have to live with ;-)

As such it really is no big deal. You should download the 10.7.4 OS Installer from MacAppStore.
Clone/restore the InstallESD.dmg inside the .app to an 8GB flash drive. Now you have a recovery disk and installer all in one. Carry it with you ;-)

Yes I have in fact done what you suggest but of course it isn't the same.

I just find it rather odd with their software development prowess and owning the OS they can't solve this limitation since they base their "Find my Mac" around having that partition.

If someone steals my mac will I now have to ensure they steal the flash drive and make sure they understand they need to keep the flash drive inserted so that they can be caught?? LOL

Yes I am aware there are 3rd party solutions but why should I be forced to purchase something that all other mac users get free when the problem is essentially apple's for not fully supporting their "OWN" raid implementation.

I understand ;-)

But overall by Apple's design MacBookPro's are not supposed to have 2 drives RAIDed.
Certainly nice to have (and on my list of things to do 240GB SSD + 750GB hard disk in my MBP). Optical drives are rarely used at my sites now.

Most desktops do not need FindMyMac and it is just a limitation of how recovery partition works. I have servers with RAID5 do not miss RecoveryHD as we are not using FileVault or Find My Mac.

I personally would not bother running RAID 0 with SSD anyway as SSD is fast anyway.
I run non-raided Boot disk and DATA drive. Less chance of things going wrong too but you know that.

Why do you "need" RAID 0 with your SSD's ?
I know there is a speed gain but this usually used on enterprise database i/o or AFX/FCP render/playback uncompressed HD,2k,4k etc.

This link doesn't provide a solution, but there is some interesting discussion:
