Hi wonder if you could help me out? I follow the guide and everything went well until this point. When I type in dd if=boot1h of=/dev/rdisk2s3 I hit return and it said operation not suppoted

Ron, it looks as if you are loosing track of your raid set members. The Diksutil list inticates that the two are disks 0 and 1. When you try to dd to rdisk2s3, you are attempting to write to the 1 TB drive.

Good modding,

Hi neilhart, Just to get back with you that after making changes on dev/rdisk0 and 1 disk everything when just fine. That what happens you go to fast. I was typing all the commands in the Terminal it brought me back to the old "DOS" DAYS. Ha! I put two Scan Disk
Extreme !! 240 GB and they scream. I use the Black Magic speed test and got 600 read and over 1000 write. I also back everything up because I have use raid for a long time. I sent you a friend request also

Thanks again,

Ron (n9bug)

Neilhart, I hope you saw my reply to you. I have another problem: Did you have any problem with iMessage not work when you made your Raid0? If you did what did you fix it? I have try different things. I use File NVRAM.Dylib ( It work when I had a single drive)
There is a post to use the latest Chameleon Wizard. By the way I have Chimer 2.2.1 install. What is your thoughts?

Thanks

Humm... well I just checked and iMessages does not work on my machine(s) with or without booting to RAID 0 sets. App Store and iCloud work. I do not use instant messaging on my desktops and it appears to be a mess to correct so I will not at this time.

Good modding,

thanks for the tutorial, very good indeed!

i followed all your steps, it worked perfectly till i rebooted the computer for the 2nd time, and the raid was broken... any advice so it does not happen again?

i am busy redoing all your steps again.

thanks

Hey neilhart, great tutorial, though I mucked something up. Had it all running once well, but had to do a full system reinstall so I deleted the RAID0 config, wiped the drives and remade the RAID0. Though once I finished your guide, it wouldn't boot! it get's stuck at the apple loading screen. Any ideas what could be going on? I'm stumped.

Thanks!
Lokin

EDIT:

Got it!
Instead of just erasing the drive, "diskutil zeroDrive disk[x]" did the job!

Hello Neil,

is sleep/deep sleep working on your raid0 boot configuration with Mavericks ?

Greetings Bert

Any news on the trim problem? How can I check if trim works with my raid 0? In system info I see that the two drives support trim, but the "raid disk"?

hi
i use this steps
fdisk -f boot0 -u -y /dev/rdisk0 [Enter] (First drive in Raid)
fdisk -f boot0 -u -y /dev/rdisk1 [Enter] (Second drive in Raid)

dd if=boot1h of=/dev/rdisk0s3 (First drive in Raid)
dd if=boot1h of=/dev/rdisk1s3 (Second drive in Raid)


diskutil mount disk0s3 [Enter] (First drive in Raid)
cp boot /Volumes/Boot\ OS\ X/ [Enter]
cp -R Extra /Volumes/Boot\ OS\ X/ [Enter]
diskutil unmount disk0s3 [Enter]


[sh-3.2# cp boot /Volumes/Boot\ OS\ X/sh-3.2# cp -R Extra /Volumes/Boot\ OS\ X/
cp: Extra: No such file or directory

what this meaning ?
