Not that I recall; but then again I have a bad memory. Don't make work,
but if you find the link for such a message from me I'd like to review
it.
My Athlon64 uses SATA and all my other boxes use PATA so I've never
moved a drive from one to the other.
I use routinely the raid1/boot, raid1/LVM combos for the system
directories with plain LVM on normal partitions for /home. When I get
into video editing, I plan to put /var/tmp (or whatever) on a striped
LV.
I'm also a big fan of LVM for my old boxes. Old boxes have old drives.
So far, the old drives have given some pre-failure warnings (non-SMART)
in syslog before the filesystem gets corrupted. Its nice to be able to
add a drive to the system and migrate the data, without needing to keep
two drives in the box for raid1. Also, no two of my PATA drives are the
same size.
The only problem with installing that I've had consistently is that GRUB
doesn't end up on the disk. I think I've tracked it down to the
partitioner forgetting that I've set up the /boot partition whenever I
set up something else. My recent re-install of my Athlon64 box (wanted
to change from JFS back to ext3) took me 4 hours just to get the
partitioner to work right; I had to keep starting the install over.
Luckily, I have CD-bin1.iso since I'm on dialup.
Thanks,
Doug.
