ErmaC Posted November 23, 2012 Share Posted November 23, 2012 I try different ways but w/o success... Is like the Software RAID... no Recovery Partition. :-( Fabio Link to comment Share on other sites More sharing options...
Nanael Posted November 23, 2012 Author Share Posted November 23, 2012 it's the same for me I'll try more tomorrow Link to comment Share on other sites More sharing options...
ctroncosor Posted November 30, 2012 Share Posted November 30, 2012 What about making the recovery HD partition in another Drive ??? Link to comment Share on other sites More sharing options...
Nanael Posted December 9, 2012 Author Share Posted December 9, 2012 why not, but i'm not sure we can says to osX than the Recovery is on an another HDD Link to comment Share on other sites More sharing options...
tofagerl Posted January 9, 2013 Share Posted January 9, 2013 I'm easily confused and quite stupid, so I'm going to ask instead of potentially wrecking something. I'm installing 10.8.2 right now, and have created the Fusion Drive - that went exactly as planned. But what is Part 2 describing exactly, is it something I should do after I've installed ######? I see the terminal commands, but as far as I can tell it's just copying the Chameleon loader onto both disks that make up the Fusion Drive, is that right? In that case, where does the bootloader get installed, on the SSD or the HD? And do I need to do that, or is that done by the ###### installer?

Nanael Posted January 12, 2013 Author Share Posted January 12, 2013 It's not a stupid question The problem is that Chameleon, Clover or ###### can't be installed with the standard installer. So you have to install it manually on both (The SSD ans the HDD). Link to comment Share on other sites More sharing options...
jimj Posted February 6, 2013 Share Posted February 6, 2013 FYI... One of the drawbacks of the Fusion drive is that it has no fault protection, so that if either the disk or the flash fails your data will be lost, and being a composite of two physical devices increases the probability of failure. If you are using a quality SSD, the likelyhood of a disk failure is much higher than an SSD failure... with that in mind I tried the following and I have confirmed that it works (quite well in fact!) I took two disk drives and used diskutility to form a software RAID 0 set (e.g. mirroring for fault protection). I then created a Fusion drive using a SSD and the RAID set. Advantages: A disk failure will not cause data loss Disk reads take advantage of mirror for better performance Disadvantages: Cost (e.g. two disks used for the capacity of one effectively doubles cost) CPU overhead for software RAID 0 (meaningless IMHO for real world applications) Thought others might like to know this works... -JimJ P.S. Even with mirrored disks backups are still a requirement! Link to comment Share on other sites More sharing options...
Nanael Posted April 26, 2013 Author Share Posted April 26, 2013 That a good idea but in fact the cost of this solution is the biggest disadvantage… Link to comment Share on other sites More sharing options...
jamiethemorris Posted April 27, 2013 Share Posted April 27, 2013 I just have a carbon copy clone of my fusion drive. Here's something worth knowing: duplicating one half of a fusion drive setup works just fine. My hard drive in my fusion setup was failing, so I got a new one and thought I'd see if I could just clone it and swap the drives out. So I used dd to copy the entire drive over to the new one, swapped them out, and started it up. It worked flawlessly. Link to comment Share on other sites More sharing options...
Nanael Posted April 27, 2013 Author Share Posted April 27, 2013 That is not very a surprise. Because the fusion drive is juste a logical volume so in fact either CCC or Time Machine can clone what there is on Link to comment Share on other sites More sharing options...
HBP Posted August 29, 2014 Share Posted August 29, 2014 I believe almost everyone who is out there playing with this has not been actually using a Fusion drive... after refollowing the steps from the before mentioned guide, I got to the part of making a LVG, but I named it 'FUSION' without the ' marks, then I went into disk utility (the Graphical interface) and did a repair disk on it, it asked it I wanted to restore a working Fusion Drive. I clicked yes. and now I have a Fully working Fusion Drive.
