Hello,
sorry, I forgot to tell that `/proc/cpuinfo'
shows up _two_ processors (when the kernel is a SMP one).
Furthermore,
the concerned black box is a very old one:
before september 2003 (kernel 2.4.22).
According to `/proc/cpuinfo', there are two
Intel(R) Pentium(R) 4 CPU 3.20GHz (model name)
with `stepping' 9.
As I may need a lot of CPU time, I would like to know
if it makes sense to install a SMP kernel on this black
box (and its shelf brothers):
who must I try ?
Can a SMP kernel be confused by a one CPU computer
(and announce two CPU instead of one).
Thanks in advance,
Jerome

That sounds like high mathematics for me.

Installed all according instructions. Sound juicer doesn't like to
accept new format, but doing job well now. The new problem arised -
nothing want to playback m4a.

The disks have 500, 400, and 160 GB. They are used by VDR to store digital video in an MPEG2 based format. I probably can't gain much by attempting to compress the data.
Having a backup would sure be nice, but its not what I attempting to achieve at the moment. I guess if I wanted to be on the safe side, I'd buy two 1 TB drives and build a RAID array. Right now, I was just hoping that I could migrate from three separate partitions (managed by VDR) to one LVM partition in order to ease mounting via NFS now and drive replacements later.

The next disk I buy is going to be a 1000 GB model. Moving from regular partitions to LVM shoudn't be a problem then. But at the moment, 1 TB disks are still a little bit to expansive for me.
