Trouble building Fusion Drive in 10.9

[[idkfa]]

Hi everyone,

 

I have trouble building a Fusion Drive. The error I am getting is "LVG on disk0s2+disk2s2 is damaged and mounted read-only", a message about fsck_cs finishing with status 0x04 and an error "LVG MLV is readonly because metadata is not writable".

My current setup:

GA-EP45-DS3

Samsung 840 Evo 250GB + Western Digital WD20EARS-00MVWB0 (2TB)

WD 750GB drive I am currently booting from and is to be replaced by the fusion drive

All drives connected to the internal sata

Mavericks 10.9

 

I am getting the above error message in the Mavericks Installer as well as in Mavericks installed on the 750GB drive.

Do you have any suggestions?

 

Greetings
