Yosemite recovery partition - gone?

In the second terminal command the lvUUID that you enter in this command "diskutil coreStorage revert lvUUID" is the string of nuber from the first command.

What did the first terminal command return?

I followed the instructions yesterday and it worked.

I think my Recovery HD partition went missing in Startup Manager after I ran "Recovery Disk Assistant" in an effort to have a Yosemite recovery partition on a USB drive. I see now in the requirements section for Recovery Disk Assistant a note that says:

"This utiltity is not compatible with a disk that is using CoreStorage,

including any disk larger than 2.2TB, any disk with FileVault 2

enabled, and all Fusion drives"

Oops! Command+R still works so I hope this is the only issue with running Recovery Disk Assistant in Yosemite.

Does henrik-kna's solution remove CoreStorage use altogether and "convert" the main Yosemite partition back to the way it was in Mavericks or will you still have a CoreStorage setup after the "revert"? If CoreStorage is removed then is there a way to get back to how Yosemite had it configured with CoreStorage?

I had the same issue. I did one Mac and the recovery partition was there. I did another and it was gone. Both Macs have the same setup and apps. I reinstalled the OS and still missing so not sure what is going on.

diskutil cs list

No CoreStorage logical volume groups found

This say how to reinstall the recovery partition

I solved with this! Thank you very much!

Genius!

Thanks so much for this.

The recovery partition is now visible and I can make one for Jamf imaging deployment, Yosemite.

Thx for the tip to remove the LV this worked perfectly. Another question you might have a clue on is my TM volume does not show in Startup Manager. The external disk has multiple partitions and the first one called CCC which is a Carbon Copy Clone of my disk shows. I typically use that method for recovery especially if my Recovery Volume goes missing which it has before. If I connect my old laptop with Mavericks installed it sees the recovery volume and the CCC volume. Any ideas

Thank you henrik-kna.

This worked perfectly for me. I had created a USB installer for Yosemite and installed it from the flash drive. Seems the recovery partition disappeared in this process along with Find My Mac. Now both the recovery partition is back (shows up as EFI Boot) and Find My Mac are back. Much obliged.

Thank you! That solved my problem. When Yosemite upgraded I chose NO for FileVault, however my volume was converted anyway. When I opened the disk with iPartition it showed up twice! The 2nd entry for the disk said there was no partition table available. Bootcamp also would fail to work since it said the disk wasn't a single OS X partition.

This was very confusing -- your post converted my disk back to "normal" where things make sense again.

Did you ever resolve this? I have no idea what to do. It's like my hard disk no longer exists. This is all because of filevault and yosemite. I never had any issues before I upgraded to Yosemite and it turned on filevault. I'm going to talk to the "genius'" about it tomorrow and I suspect that they will try to blame it on hard drive failure. This is such nonsense.

Did you ever resolve this missing partition issue? I have no idea what to do. It's like my hard disk no longer exists. I can only boot in Internet recovery mode and my hard disk doesn't show up. This all started because of filevault and yosemite. I never had any issues before I upgraded to Yosemite and it turned on filevault. First filevault stopped encrypting mid-way through saying I needed to plug in my mac, even though it was plugged in, now my computer is completely dead.

I did the cslist thing and I got the same no corestorage....error others have reported. Please help if anyone has a solution.

Installing File Vault stressed the HD a lot and thus can tip a marginal HD over the edge of failure.

You can make sure the the connectors on the HD a firmly connected and reseat the,

Hi,

Thank you very much this work with me.

🙂

Recovery partion was there

I've just turned off FileVaul, so aftermath, I decided turn it on again and I didn't get that cause Yosemite warns me that recovery partition is not there anymore.

IS There solution for it without reinstalling Yosemite?
