What's he's saying is that RAID and LVM do not need partitions to work properly. You can create a raid array on the raw(unpartitioned) /dev/sdX devices and then create a LVM volume group using a physical volume(PV) on a raw(unpartitioned) /dev/mdX (RAID) device. The filesystem still needs a partition/volume but that can created either by partitioning /dev/mdX *or* creating a logical volume in LVM. =46or example, on my system at home I use RAID-6 created using /dev/sd[b-f]. The resulting /dev/md0 acts as a physical volume for LVM and I've created several Logical Volumes aka "partitions" for the filesystems to reside in. > Seems like journalling/crash recovery is pretty vital. =C2=A0Could no= t partitioning be recommendable? See above. You still have a partition/volume of some sort where the filesystem is created. --=20 Drew "Nothing in life is to be feared.
