Fusion Drive on a 27-inch Mid 2011 iMac

Posted by ronald on juni 24, 2013 in Nieuws with Comments closed |

The project

This is a story about making my own Fusion Drive on my 27-inch mid-2011 iMac.

The iMac

27-inch mid-2011 iMac with 12GB internal memory

Mac OSX 10.8.4

 

The Hardware

At Informatique I bought:

Samsung 840 Series Pro 256GB (costs 219 euro)

WD Scorpio Black 750GB HDD 7200rpm sATA (costs 69 euro)

At OWC I bought:

OWC DIY Kit for all Apple 27″ iMac 2011 Models for replacing the main hard drive. (costs grand total including shipping 49.24 USD + 20 euro customs (next time use DHL instead))

OWC DIY Kit for all Apple 27″ iMac 2011 Models for installing an internal SSD into a system currently equipped with hard drive only. (costs grand total including shipping 57.78 USD + 20 euro customs (next time use DHL instead))

 

 The Backup

I used a free version of SuperDuper to make clone of my original 1TB 3.5-ich Seagate Baracuda to a 2.5 inch drive on stock in a Firewire Dock. This way I was able to boot from the FIrewire disk with a exact copy of the original disk. Of course I also created a Time Machine backup.

 

The Hardware Operation

I followed two movies from YouTube

“How to Replace the Hard Drive in a 27 iMac [2011]”

“OWC Internal SSD DIY Kit for all Apple 27 iMac 2011 Models”

 

Remarks on the movies:

It is not that simple as it seems to look.

Also my iMac had some modifications.  Like more cables on the display. (4 instead of 3)

It took myself 3 hours to get this done. (But this was the first time)

 

Making the Fusion Drive

Boot from the Recovery Disk / Cloned Mac OSX and open a terminal as root

Identify the 256GB SSD and 750GB 2.5inch disk with the command:

# diskutil list

In my case: disk0 and disk1

Next create your core storage volumegroup with:

# diskutil coreStorage create FusionDrive /dev/disk0 /dev/disk1

Watch for the LVG UUID. You need that in the next command

# diskutil coreStorage createVolume \

50B457C3-ADC6-4EDC-9ABA-FD8C6EEDE69A jhfs+   \
“Macintosh HD” 100%

That’s it. Your Fusion Drive is created!

Now use SuperDuper to clone the Mac OSX system again back to the “Macintosh HD”

 

Conclusion: At the end the cabling stuff from OWC makes the project a bit costly. But the result is very satifying. Also next time first deinstall Little Snitch from your OS. I had to reinstall it because it was acting strange after the cloning.

 

Issues:

Why is my Drive Fan running full speed after 10 minutes. I have this temp sensors cable from OWC which should prevent this.

I tried SMCFancontrol but was not able to get it reduced.

I checked HDD Fancontrol 2.4 which seems to work.

But I bought this cable for that reason. So that is a bit strange.

Hopefully Technical Customer Service is bringing a solution/explanation.

Update: OWC support sent me an e-mail. They will sent me a new cable. Hopefully this fixes it.

 

 

 

 

 

 

 

Resizing Ubuntu 12.04 Precise filesystem with LUKS LVM2

Resizing Ubuntu 12.04 Precise filesystem with LUKS LVM2

First is to backup your filesystem you want to modify.

First boot of LiveCD and choose “try without installing”. Although it is said to be possible online, it still is risky so I do it offline.

Open a terminal

$ sudo -i

# apt-get install lvm2

# cryptsetup luksOpen /dev/sda2 crypt-sys

# pvscan

# vgscan

# vgchange -ay

# e2fsck -f /dev/ubuntu/root

 

Shrink filesystem to 100GB

# resize2fs /dev/ubuntu/root 100G

# lvreduce –size 100G /dev/ubuntu/root

 

in progress…

(Tested on Ubuntu 10.04)

 

First boot of LiveCD and choose “try without installing”

Open a terminal from Menu Accessoires

# cryptsetup luksOpen /dev/sda2 crypt-sys

# pvscan

# vgscan

# vgchange -ay

# cd /mnt

# mkdir root

# mount /dev/ubuntu/rootfs root

# mount /dev/sda1 root/boot

# chroot /mnt/root

# mount -t proc proc /proc

# mount -t sysfs sys /sys

# mount -t devtmpfs devtmpfs /dev

# mount -t devpts devptr /dev/pts

# update-initramfs -u -k <kernelversion>

or

# update-initramfs -u -k all

# grub-mkdevice

# update-grub2

# sync;sync;exit

# reboot

 

Now it should boot!
