I have to setup 14TB of raid storage space (which just shows up as /dev/sdb). My question is:
Is there any impact on performance from a kvm guest if I create ext4 on this large drive directly, mount it up on the host like /mnt/kvms and then create raw kvm disk image on it?
Would it be a lot faster to configure /dev/sdb in the kvm machine directly?
I see it as a pro that if something would happen with this large storage area I could not do much with it if I use the device directly but let's say I create 2x7TB kvm raw-disk files on it, if 1 file has a problem at least I still have my data accessible in the other one.
What do you think?
