Fusion Drive help, Keep getting errors.

Question

I just installed a SSD in my MBP 2009. I want to turn it into a fusion drive. I&#x27;m following the directions on the internet, and this is what I get..."-bash-3.2# diskutil list/dev/disk0   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      GUID_partition_scheme                        *120.0 GB   disk0   1:                        EFI EFI                     209.7 MB   disk0s1   2:                  Apple_HFS Untitled                119.7 GB   disk0s2/dev/disk1   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      GUID_partition_scheme                        *500.1 GB   disk1   1:                        EFI EFI                     209.7 MB   disk1s1   2:                  Apple_HFS Alex Erlenbach&#x27;s Mac... 499.2 GB   disk1s2   3:                 Apple_Boot Recovery HD             650.0 MB   disk1s3/dev/disk2   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:     Apple_partition_scheme                        *1.3 GB     disk2   1:        Apple_partition_map                         30.7 KB    disk2s1   2:                  Apple_HFS OS X Base System        1.3 GB     disk2s2/dev/disk3   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *524.3 KB   disk3/dev/disk4   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *524.3 KB   disk4/dev/disk5   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *524.3 KB   disk5/dev/disk6   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *524.3 KB   disk6/dev/disk7   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *524.3 KB   disk7/dev/disk8   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *6.3 MB     disk8/dev/disk9   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *2.1 MB     disk9/dev/disk10   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *1.0 MB     disk10/dev/disk11   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *524.3 KB   disk11/dev/disk12   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *524.3 KB   disk12/dev/disk13   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            untitled               *1.0 MB     disk13-bash-3.2# diskutil corestorage create AlexErlenbach&#x27;sFusionDrive /dev/disk0 /dev/disk1&gt; diskutil corestorage create AlexErlenbach&#x27;sFusionDrive /dev/disk0 /dev/disk1Started CoreStorage operationUnmounting disk0Repartitioning disk0Unmounting diskCreating the partition mapRediscovering disk0A problem occurred; undoing all changesError: -5343: MediaKit reports no such partition-bash-3.2# diskutil corestorage create AlexErlenbach&#x27;sFusionDrive /dev/disk0 /dev/disk1diskutil corestorage create AlexErlenbach&#x27;sFusionDrive /dev/disk0 /dev/disk1Started CoreStorage operationUnmounting disk0Repartitioning disk0Unmounting diskCreating the partition mapRediscovering disk0A problem occurred; undoing all changesError: -5343: MediaKit reports no such partition-bash-3.2# diskutil corestorage create AlexErlenbach&#x27;sFusionDrive /dev/disk0 /dev/disk1diskutil corestorage create AlexErlenbach&#x27;sFusionDrive /dev/disk0 /dev/disk1Started CoreStorage operationUnmounting disk0Repartitioning disk0Unmounting diskCreating the partition mapRediscovering disk0A problem occurred; undoing all changesError: -5343: MediaKit reports no such partition-bash-3.2# -bash-3.2# diskutil corestorage create AlexErlenbach&#x27;sFusionDrive /dev/disk0 /dev/disk1diskutil corestorage create AlexErlenbach&#x27;sFusionDrive /dev/disk1 /dev/disk0Started CoreStorage operationUnmounting disk1A problem occurred; undoing all changesError: -69888: Couldn&#x27;t unmount disk-bash-3.2# "I don&#x27;t understand what I&#x27;m doing wrong.Help?

aerlenbachI successfully followed the blog.centurio.net and pintofcode.com procedure to set up a Fusion drive on my 2011 IMAC with SSD &amp; HD yesterday.I did at one point have the 69888 error.   To correct this:In the procedure for (Pintofcode)MERGING THE DRIVES, instead of booting from the recovery drive, I booted from the bootable USB stick.I hope it helps.Andy Smith5
