Greets, gentoo-users ... I am currently trying to find out why my LVM2-volumes aren't activated correctly at boot time. I am using packages from the overlay systemd-love as I run systemd as init-system (why? that's another discussion ;-) ). Until now I always was kind of lazy and used genkernel

Hello Nick, the question is, what are you doing with it and why do you think you need a fibre channel SAN. Our goal indeed is to get rid of the SAN infrastructure as it is delicately to all kinds of failure with nearly zero fault tolerance. An example, you have an hicup or a power failure

Hello, I tend to disagree. A correctly designed SAN (using dual Fabric among other things) is a lot more stable and has a lot better performance than any NAS (NFS, CIFS, iSCSI) solution. One other thing that also needs to be correctly configured to have a stable SAN infrastructure is the
