this core storage operation is not allowed on a sparse logical volume group

Same issue here... No mater how much free data you have it won't install. Guess I won't be using the Beta if it's going to be this troublesome!

I saw that once last year or the year before with the first Yosemite resp. 10.9 beta, actually AFTER the first beta. There was a bug in the first beta that created a combination of nested logical volumes that made re-partitioning without erasing the whole layout impossible. I was only able to get rid of this (after trying for several days) by erasing the drive and start from scratch.

Same deal here....I guess i could wipe my drive.. but really, it would be nice not to.

has anyone found a solution to this problem yet?

I gave up and erased my main harddrive and did a clean install of os x 10.11

I got the same problem but don't want to erase everything and start from scratch. Hope they come with a solution very soon.

after 4 days no one got the same error? I did, cannot imagine how to solve it. Thanks

I have this issue too!! Please someone tell how to solve it.

Long story short, you're going to have to wipe your HD and reinstall.

Long story long, run a backup (Time Machine is fine), then boot into Recovery Mode. From there, you'll have to do some command line work, so if you're not comfortable doing that, your best bet is to either wait till Apple provides a solution or hold off on installing the beta. If you're OK with working through the command line, from the Utilities menu, choose Terminal and enter:

diskutil coreStorage list

and see what returns. My drive had 5 or 6 branches to the tree it will display and, I believe, this is where the problem lies. How they got there I'm not sure. Maybe it was a relic from installing Yosemite betas. Either way, they are what was causing the problems for me. I believe the default number of entries (look for the + symbol in the results) to be four listings. I then ran:

diskutil coreStorage delete "insert base Logical Volume Group name here"

where you will insert whatever the name of the base level Logical Volume Group without the quotes. THIS WILL WIPE YOUR DRIVE!!! BE SURE YOU HAVE RAN YOUR BACKUP BEFORE DOING THIS!!!

From there, you can close Terminal and you should be brought back to the main Recovery menu. Reinstall OS X from your Time Machine backup. It'll take some time depending on your backup size, the drive you backed up to, the drive you're restoring to, etc. I have a 256GB drive in a first edition Retina 15" MBP that was backed up to a USB 2.0 external drive and the total recovery time was around two hours. Then try running the 10.11 installer. It worked for me without issue.

thanks, very interesting. Might be my case a little different? is seems there is onlune one volume in rMBP. Ran the command line to found the following:

CoreStorage logical volume groups (1 found)

Any other possibility?

thanks
