We have not really had major outages yet... Most of our stuff is already
at least RAID 1 (even Windblows) I might just be a little too paranoid.
I have decided that at first I will be going for the DRBD solution.
With the current hardware I have it will be the easiest solution.
Have any of you guys used GlusterFS or OCFS yet?
