Virtualization Software RAID-1 LVM has also been mentioned Maybe we could outline the plan in advance? V12n if XEN, are there details to be chosen? is VMWARE something that should be considered generally, are there any special preparations/rehearsals needed for failure recovery? RAID RAID-1 2 disk mirror multiple GRUB setup to ensure bootability when 1st disk goes partitions (one possibility follows) md0 boot (for kernel, grub) -- grub can boot off md, yes? md1 emergency-rootfs (small ubuntu? diagnostics?) swap1, swap2 (need not be mirrored) md2 LVM -- all the rest mainrootfs tmp, var, varlog (..? eg, varcache?) opt, usrlocal (..?) srv (more than one?) discussion?
