Fusion drive

[Monistee]

Good evening all. I'M HAVING A PROBLEM WITH SETTING UP MY PARTITION. I HAVE A FUSION DRIVE. AND IT WON'T LET ME CHANGE IT'S SIZE. I'M NOT THE SHARPEST TOOL IN THE SHED WHEN IT COMES TO COMPUTERS. BUT I DID WHAT THE MANUAL SAID ABOUT MAKING A PARTITION. YOUR HELP WITH THIS WOULD BE MUCH APPRECIATED. THE ATTACHMENTS ARE PICS OF THE DISK UTILITY. HAVE A GOOD ONE ALL! I'M NOT YELLING POOR EYE SIGHT!

You can add only one additional partition to a Fusion drive. Once a second partition is added neither can be resized. You can remove the second partition and re-add it in a different size. But that's about it.

Also, I noticed you are booting off the second partition. Only the first partition is the actual fusion drive (SSD+HDD), the second partition is all HDD.

P.S. It can be done using the command line version "diskutil" but you'd need to be pretty comfortable working in Terminal.

hey once again. I should of made it clearer. I'm wanting to make yosemite the one, and only drive. Yosemite is mavericks 2. I forgot to change it from mavericks. I have all my apps already downloaded on it. So i'm hoping not having to lose any of it. On my old mac i just upgraded from, i had no problem doing this. But this mac is a fusion drive. And i know very little about it. And i'm being generous to myself by saying that. Have a goodone all!

hey marzer. Thanks for your quick reply. I did erase all off the maverick which is the fusion drive then. But i can't remove it. That sucks. I just spent 5 days downloading every app i have to yosemite. So i guess i'm stuck with it. I guess i'm screwed. You take care and thanks!

Yet another reason why I went for a pure SSD setup.

Messing around with Core Storage configurations in Fusion Drive is more trouble than it's worth.

If you have a backup of your system you could restore to a single partition, install Yosemite then restore your system.

do you mean backup yosemite. Then erase all. Then restore it once again. When i restore would that restore all my apps also. And thanks for your time!

Yes, basically just do a Time Machine backup to an external drive, then reformat the entire Fusion Drive and fuse it back into a single logical volume group, then just do a Time Machine restore. That would restore everything, including settings, apps, etc.
