Q: Fusion Drive on Macbook Pro & Hibernation problem

Hi,

 

Two weeks ago I installed second SDD in my Optibay (Macbook Pro mid2010 13"). Now I have HDD (Seagate Momentus XT 750GB) + SSD (Kingston V300 60GB) in configuration like that:

 

1) HDD in normal bay (because of SMS)

2) SDD in optibay

 

I configured this drives to work as Fusion Drive (it's really fast now!), but the main problem is hibernation (known as deep sleep also).

 

When macbook goes sleep whole memory are written to disk (in my case - fusion drive), and when the battery die it should be resumed from disk. But I found, that people using OS X from optibay drive can't use hibernation. In this case the main HD is expanded on both drives (SDD + HDD), so this is a problem - memory image should be readed also from optibay/normal bay drives.

 

Is there any workaround or any chance to get hibernation on fusion drive working in Macbook?

 

The main reason I'm looking for solution is low battery problem - I can't sleep safely my computer on 2-3% of battery and I don't want to turn it off...

 

Best regards,

Dawid

MacBook Pro, OS X Mountain Lion (10.8.2)

    I have the same physical setup (though it's a MacBook 5,1, the first unibody 13"), but haven't tried Fusioning-it. (I have been holding off for 10.8.3 in the hope that it will have a properly fusion-aware Disk Utility when I get into trouble; my understanding is that all official Fusion Drive systems have a custom build of 10.8.2 with changes in Disk Utility and, I assume, diskutil.)

     

    As far as I know, and I'd love to be proved wrong, hibernation just can't work if the SSD is in the optibay (as mine is as well). It doesn't get power immediately on wake so it just doesn't work. The only thing you can do is disable hibernation support so that the system doesn't even try (saving you the hibernation-image space on the SSD); set OS X to restore your windows when you log back in; and then shut down when you're nearing zero battery. Alas.

     

    If this can't be made to work when the SSD is the boot volume alone, I can't imagine there's a way to make it work when it's in fusion drive.

    i'm in the same boat with my fusion drive set up (ssd in optibay) and i miss waking my mac up from hibernation after the battery dies.

     

    i loved this feature when i was on snow leopard and never really had to worry about shutting down my mac and keeping it charged

    I have the same issue although my ssd isn't in the opti drive.  Same setup as Scott.  I didn't think I had this issue, but I have realised that my battery life is suffering a lot after the fusion setup and consequently it is draining quickly in sleep as well.  My issues are that it doesn't seem to go to sleep properly (if it is hibernation it takes forever), the battery is draining fast in sleep and when it runs out during sleep the computer effectively shuts down.  The strange thing is that this has only started happening recenlty and I put the ssd / fusion together quite a few months ago with no issues.

     

    Any suggestions?

    Hey!


    I have the same problem... but I do not have the ssd in the optibay, I have it in the regular bay. But I guess that the problem is that the sleepimage is stored in both disks, because it is not enough space in the SSD. There is just 4 gb buffer. When the mac wakes up, it cannot find the sleep image.
