Cause of Late 2013 Imac Kernel Panic

I have just got home from work to find my imac in a cycle of kernel panics. I have tried entering safe mode by holding the shift key when booting up with no luck (I'm using the apple wireless keyboard and there is no startup chime so I am waiting for a second or two).I would be grateful if anyone could diagnose the problem from this log and give me any adive to get back up and running:

panic(cpu 2 caller 0xffffff7f9d12bac5): "This LVG was created before the fix for <rdar:11023142>, you must recreate your LVGs"@/SourceCache/CoreStorage-380/core/btree_impl.h:55

Log file locations

Mac OS X v10.5 and later

If a kernel panic occurs, information is added to a log file in the folder /Library/Logs/DiagnosticReports (Mac OS X v10.6), or /Library/Logs/PanicReporter (Mac OS X v10.5).

How can i get to this location, it is a reccuring kernel panic and I cannot get onto the machine?

Thanks

If they machine will not boot to the point where you can log the KP then you have no choice but to take it to your local Apple Store or AASP for a professional diagnostic. I suspect you have suffered a hardware failure however without seeing the KP report there is no way we can diagnose it.

If you upgraded the RAM yourself you can try by swapping out the original RAM for the upgraded RAM and it could also be a failed HD or main logic board.

If the machine is covered by AppleCare any hardware repair would be covered, if it's not then you will need to pay for the cost of repairs.

Good luck!

You have a corrupt Core Storage volume. What backups do you have?

Linc.

Unfortunately i dont have any backups of the system. It is a pretty fresh install as i have only had the machine for a couple of months and there isnt masses of data on there that im concerned about losing. I havr got the 1tb fusion drive installed, do you think this is the culprit?

Ps. I have already tried comand-r with no luck so it looks like there isnt a recovery drive setup.

What do you think is the best way to proceed?

You have a 1 year warranty and if you bought AppleCare you can call them to arrange for repair. If you did not get AppleCare I would STRONGLY urge you to do so while you still can, this will extend the warranty from 1 to 3 years and give you 3 years of telephone support.

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Keeping your confidential data secure during hardware repair

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

*An SSD doesn't need to be zeroed.
