End Partitioning Hassles with LVM

[Warren Togami]

LVM supports software RAID 1 mirroring and RAID 0 striping, but yes Veritas
is supposed to be much better.

> This can be a useful way of dealing with needing more disk space, but it
can also be risky.  Concatination is simple and convienent (when one disk
gets full continue writeing on the next disk), but it also means if one of
your physical drives fail, you loose all the data that is spanning all the
drives!  There is no redundancy.  This technique is generally used in place
of raid 1 (striping).  Sun Solstice has had this feature for a few years.  A
better choice for volume managment is Veritas Volume Manager and File
System.  It can actually resize partitions on the fly and has exelent
redundancy.  I thought I heard they were going to make a Linux version.
