In Yosemite 10.10.2 after verifying my startup disk in disk utility I got this message...
"This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility."
As per instructed I rebooted in recovery mode and tried to repair the disk from there. The problem is that in recovery mode my startup partition shows up as "unmounted encrypted disk partition", and all options including verify and repair are greyed out. The core storage volume can be repaired but it comes up clean.
What do I do, is this problematic? My computer appears to be running smoothly in general, I just verified the disk out of curiosity and now I'm faced with this issue.
