DIY MAC Fusion Drive

I'd like to create my own MAC Fusion Drive, but I'm not a dev so I need a little bit of guidance, which would also help a lot of people I'm guessing.
I am trying to follow jollyjinx's instructions, which are not that detailed. Specifically, I am trying to find the names of my two drives and I can only find one. Maybe the drives are not connected in a way to do this I'm not sure. I have a 750GB HDD and an 80GB SSD installed internally in my 2011 Mac Mini. I have been using both drives, SSD for the OS and a handful of common files and the HDD for iPhoto and iTunes libraries. A Fusion drive would be perfect!
When I run dmesg in Terminal, here is what I get:

I can only find one reference to a drive in the data, but maybe I'm missing something. Any help would be greatly appreciated!

So far, so good! The article steps worked perfectly. I setup the Fusion Drive and then restored from my Time Machine Backup (from the SSD). I then moved the files over that were on the HDD (which I also backed up on my external drive. Everything seems to be working great! The volume was previously named 80 SSD OS X (to differentiate from the HDD) and it is still named that, although, as you can see from the screenshot, it now has a 576GB capacity (not 750GB, which is what I thought I put in there--my memory is horrendous! lol) ....not a big deal. I consider this a huge success at this point. Thanks again for the article!

Cannot access mac fusion drive in bootcamp windows 7

My Fusion drive imac cannot access the Mac fusion drive in bootcamp windows 7. even I installed the bootcamp 4.1on windows 7. It is trouble as I cannot get my file in the mac drive in windows.
I don't have this problem in my old imac 2008.

Mac Fusion drive: The disk "Macintosh HD" could not be unmounted

Hi
I recently purchased a Mac Mini with the fusion drive. When I perform a verify and repair of the disk, I get the error "The disk Macintosh HD could not be unmounted". This does not occur with any of my other computers, imac or powermac (also running mountain lion). So I am wondering if I have a defective Fusion/HD or if this is simply a peculiarity of the fusion drive itself. Please comment.

If your Fusion drive can be repaired with Disk Utility, it will be shown with red lettering. If you are not seeing red lettering, then you need to boot into Recovery mode to use that Disk Utility. When you order a Fusion drive equipped Mac, there is a special version of Disk Utility included in OS X specifically for operation with Fusion Drives.
If you have any open files on the volume you wish to verify/repair, then Disk Utility will throw its hands up and give you that cannot unmount drive message. Make sure you have quit all applications you were using that may be accessing files on the disk in question.

Best SSD to DIY a Fusion Drive.

Hi there, I'd like to know if any of you have personally a SSD brand you trust. I once purchased a SanDisk SSD for my work computer which failed before a year of usage. Later I purchased a Crucial/Micron SSD for my iMac which seems to be failing now, around only over 6 months of usage. I've replaced the SanDisk with a Kingston in my work computer but I'm not sure if it'll last at all.
For my iMac, though I've lost confidence in SSDs and I feel tempted to rely solely on the HDD, I'd like to know if you can advise other very reliable SSD options since the speed of a Fusion Drive is just spectacular.
Any recommendation? Thanks in advance.
Jorge...

Do a Google search on the various brands and read the reviews about them. I haven't read of any that are outright unreliable. I haven't seen complaints about these drives failing in this forum or on PC forums. Like any piece of electromic equipment some will fail, that goes for SSD's as well as HDD's.
When you installed this SSD did you take precautions against static? Are you sure you followed all the steps in the installation process EXACTLY? Opening a newer iMac and installing a drive (SSD or HDD) is frought with pittfalls. One bad move and you can create big problems for yourself. With that said I've installed 3 HDD's and 2 SSD's in three different iMacs without problems. However I am very careful to work in a static free environment (wrist strap, static mat, etc.) I handle the components as little as possible, and take care that they are seated properly inside the iMac. It's very easy to pinch a cable or do something that will come back and bite you.
I mentioned MacSales because buying from a good vendor is just as important as buying a good component. I know MacSales stands behind what they sell, and that's important to me. (I am not connected in any way with MacSales, except being a satisfied customer)

Is there an issue using file vault 2 on a Mac fusion drive

is there an issue using file vault 2 on a Mac fusion drive

I'm using that configuration and it works for me. There have been some reports of kernel panics with FileVault and SSD's. The cause is unknown. Chances are you'll be fine, but make good backups.

Any problems with apple fusion drives?

I am in the process of ordering new iMacs with fusion drives. someone mentioned that could cause problems with Adobe Photoshop.

Damaged Fusion Drives

Hello all, I'm coming to the communities with the sad news that my iMac a few days ago started acting up, upon running a few 'repair disk permissions' tasks, I learnt that there was something unusual as it started showing messages like these:
Open error 5: "Input/output error" on…
and
Open error 1: "Operation not permitted" on…
Around the same time many apps would quit unexpectedly, I was unable to log out, and basically all I did would take an awful long time. Looking up the errors on the internet I learn that they likely had to do with a drive that had gone defective. As I had DIYed a fusion drive myself, I was unable to know which one was going south, so I de-fused them and I've now reinstalled Mavericks on the SSD.
I would appreciate if anyone has a comment to make as to whether you've experienced the same errors as I have and how did you solve them. I also would like to know if there is a utility out there (free, preferently) to put both drives to the test, to be able to confirm if there's something wrong with any or both of them. What surprises me though is this...
My 2010 iMac qualified for a HDD replacement, so the new one has been in for roughly just 6 months. On the other hand, the Crucial-branded SSD has similarly been installed for only 8-9 months. The fact that any or both of them are becoming un-reliable is more than disappointing, really sadenning.
All/any help you provide will be much appreciated.

Slow boot up on 2012 Mac mini with DIY fusion drive

Hello everyone, I bought a Mac mini (2012) 2 months ago with a stock 500GB HDD.
I added another SSD to make a DIY fusion drive, and everything is working fine, except that I'm experiencing a very slow boot up.
I have confirmed both by information from the OS and some tests with command line tools, that the fusion drive itself is a success and absolutely working fine.
The slow boot up happens on cold boot only (a reboot does not have such problem).
Symptom: the Mac mini is stuck on the gray blank screen for about 40 seconds, and then finally shows up the apple logo.
Everything after this is pretty fast and fine.
I have tried the following methods and none of them seems to help:
1. Go Preferences -> Startup Disk, select the Machintosh HD. (Suggested by Apple in the Fusion Drive FAQ)
2. Verify the whole disk along with the partition with Disk Utility.
3. Reset NVRAM by holding Command+Option+P+R during boot up.
4. Reset SCM/PMU.
Does anyone have an idea on the cause of my problem?
Best regards and thank you.

Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged after the boot, during the time something abnormal was happening. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).
For example, if the problem is a slow startup taking three minutes, post the messages timestamped within three minutes after the boot time, not before. Please include the BOOT_TIME message at the beginning of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any.

DIY Fusion Drive on MacBookPro8,2

Yes, I know it's not supported out ot the box.
I've been trying to set up a DIY Fusion Drive on my Early 2011 MBP 15" with no luck.
I've been googling a bit and found several others reporting the same problems on the MBP8,2. Seems this setup works on most Mac's, just not this model. Has anyone gotten this to work with any sort of hack? Please share your experience.

In case you are not already aware of these resources here are some links
http://blog.macsales.com/15617-creating-your-own-fusion-drive
http://www.macworld.com/article/2014011/how-to-make-your-own-fusion-drive.html
There are others, but the most salient point from the first link is that it alleges the 2012 Mini is the only Mac that uses a version of Disk Utility capable of creating a Fusion volume. This sounds dubious to me though since I find it hard to believe CoreStorage is dependent upon a version of Disk Utility that exists only for the Mini. The only reason I mention this is that I consider OWC knowledgeable about the subject.
Without further details of how you intend to accomplish this I am curious how you justify the following comment:
The OS handles where the files go so I can use the time to work instead of managing where the files go for best performance.
We know Apple's Fusion Drive accomplishes these actions in firmware or software that exists in their new iMacs, but what resource led you to conclude this ability exists in your MacBook Pro, or anything other than the current production 2012 iMacs for that matter?
If you are certain it does, I may do it also. I like challenges too.

DIY Fusion Drive Problem (8,2)

Hey,
I wanted to go a step further and create my own DIY Fusion Drive. I had no problems installing the new ssd (128gb Samsung 840 Pro) instead of the hdd (standard mac hdd) and moving the hdd to the place where the optical drive has been.
I then proceeded to boot from a recovery USB Stick runing the mountain lion recovery partition on it. I configured both of these drives without any problems and finally created my Fusion Drive (visible in disk utility).
But here are things getting worse. My original plan was to recover from a TimeMachine Backup i created right before I started working on the Fusion Drive. But no, it said an error occured and I should restart the PC. After googling this error a little bit (and trying the recovery over and over again, different attempts to repair the time machine, which doesn't seemed to be broken etc.), I came up with the idea that my TimeMachine data could be corrupted and a whole backup is not possible. No problem I thought to myself.
You just try to install Mountain Lion fresh with your Recovery USB Stick and then get one or two folder from your backup that you need. But nope, installing Mountain Lion aborted with an error too while checking if my MacBook would fit the installation or something.
Last try: Cmd+R to start internet recovery. Downloaded the whole thing. Now I was able to reinstall LION fresh on my system (which of course would be the basic installation since my macbook came with Lion). Problem is: Lion doesn't know anything about Fusion Drive and I couldn't select any drive to install it on.
Right now I'm really thinking about installing the os on the ssd alone, what I didn't want to do. But I'm not seeing a possiblilty to get the system back up and running they way I wanted it to.
Now it's on you guys. My last hope. Do you have any ideas on how to fix this problem? I read so many guides and neither of them came up with the problems I have. They just say "and after configurating your fusion drive, you just install moutain lion again and you're good" :|
Thank you very much,
MrMütze

I just tried what would happen if a delete the Fusion drive again. I was able to start the installation process of LION to my SSD, but Mountain Lion still aborted with an error while evaluating my system. So it shouldn't be a problem associated with the FusionDrive.

Fusion drive DIY not using SSD

Hello community,
Recently I have bought a SSD drive for my Mac Mini 2012, in order to make a dual hard drive installation ready to build a DIY Fusion Drive with Disk Utility. Apparently it works well, I have installed Yosemite without any problems and been using the Mac Mini normally. The problem is that it's very slow performance when it needs to read/write from disk, I've got around 40mb/s read and 35mb/s write speeds on BlackMagic disk speed tests.
In addition, checking the installation of the drives running "diskutil list" from command line (which tells me that disk0 is the SSD and disk1 is the HDD), and the disk usage with "iostat disk0 disk1 1" I can see that the OS is not really using disk0 but disk1 for all disk operations.
I noticed that eventually disk0 has movement but 99% activity is in disk1 (HDD). I believe that the normal behavior of a Fusion Drive is using SSD mainly and HDD in second instance for "not-cached" or less used files, but I am experiencing the opposite behavior.
The model of the SSD is Kingston HyperX 3K 240GB.
Please give me any advice about this issue.
Thanks for your help.
Best regards.

Thanks for your replies.
Actually the SSD it's installed in the upper bay, because I've tried to install it at the bottom but Fusion Drive seems not to work, failing disk verification and prompting me to repair disk. In the upper bay seems to work fine, but I've this this issue.
This is my "diskutil cs list" output:

Programs repeatedly crashing on my late 2012 Mac Mini Fusion Drive

I have a late 2012 Mac Mini Fusion Drive 2.6ghz, 16gig RAM running Mac OSX 10.9.4 . For the past week or so I have had a number of programs - both Apple and third party apps crash repeatedly, I have repaired permissions and restarted numerous times but nothing seems to fix it. For example Mail would crash each time I cancelled a password being accepted by Mail in a particular account, Safari has crashed for various reasons. Apple Motion has also crashed more times in the past day or so than it ever has in the past year. It's crashing when I try to add a point or node to a line in an animation I'm finishing.
Does anybody have any idea why this is happening now and does anybody know how to fix it?

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if iTunes crashed, you would enter "iTunes" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

DIY Fusion drive not working after Mavericks install

Hi Everyone,
I had setup a DIY fusion drive on my iMac 27" Mid 2011 - installing a Samsung SSD and a new 1TB drive. Everything was working swimmingly in Mountain Lion but as soon as I upgraded to Mavericks - everything slowed down.
In speed test I get an average write speed of 70 MB/s and a read of about 100MB/s...
Did I do something wrong? I installed Mavericks via the App Store.
Thanks.
Martin

Did you ever figure this out? I have a similar experience (read below) and wanted to know if anything you learned helped?
Hi all. I have a 3.2GHz i5 w 24 GB of Ram. Purchased in January 2014.
My good friend helped me install a DIY Fusion. I purchased a 256GB Samsung 840 Pro SSD and he did the work to "fuse" it with the regular 1TB HD the iMac came with. It is attached via USB 3.0 in an OWC case.
Originally, after being set up - Black Magic Speed tests benched it at 250-350 write and 500-650 read. I'm not a techie, but spent enough time to know that is pretty smoking and well above a typical disk hard drive.
Well, now it is down to 70-80 write and 180-250 read. The imac still boots in less than 25 seconds, so I don't feel the system is slow. (and it certainly blazes next to the first generation aluminum iMac I had before - a 2008 model). But I am concerned at deterioration of speed and really thought the extra investment would have led to faster sustained speeds.
So my questions are:
* Does anybody have any ideas why this is happening?
* Any idea what the fix is? I'm hoping not to have to start over.
* Any ideas whether it would have been better just to keep the 256 a boot drive for OS & apps, and leave the 1TB for media? I almost did this and wonder if it would have simplified things or led to better performance.
* Any idea where to go from here?
BTW, I know a little about TRIM, but I think my friend said the Samsung will handle that itself.
Lastly, you can probably tell I know a bit ABOUT this stuff, but not much on HOW to do it. So regular maintenance and upkeep is not my strong suit.
Thanks in advance for comments & suggestions.

Mac Mini Fusion Drive

I should come, and it did!
How will this work with Logic? It seems that Fusion drive will have a threshold, that prioritises most used applications.
But how will it differ from app. and content? More Q´s than answers.
What we do know: The new 21.5" iMacs will be 5400 rpm, only.
So the Mini seems to be best offer right now?

Fusion drive solution to activate Office for Mac 2011

Activating Office 2011 is a known issue for Fusion Drive Macs.
Activation is tied to the drive. According to Microsoft the solid state part of the Fusion Drive generates a new disk id every time the Mac is started. So Mac Office thinks it a new system at each startup and will require activation.
This solution was suggested by Microsoft Support. Please let us know if this works for you.
Follow the steps below to remove the “Thunderbolt bridge”:
1. Click on the Apple icon and click on “System Preferences”
2. Click on “Network”
3. Look for “Thunderbolt Bridge” on the left side.
4. Highlight the Bridge and click on the “-” sign to remove it.
5. Restart the computer and enter the Product key for Microsoft Office. Restart again.

Fusion drive solution to activate Office for Mac 2011

I don't normally advocate users re-install Office to fix an issue but in your case I think it's worth a try. The Mavericks update seems to have fixed the issue for most users. I would suggest the complete removal rather than the simple removal of dragging the Office folder in Applications to the trash.
