Problem with debian on Sparc
Hi All,
I instaled Debian on my old Sparc. In this Sparc was two 18 GB SCSI HDD
in software mirror. I have two 73 GB HDD and I want change this disks in
this server. This is production server and on this server are much data
and installed aolication. It is not possible reinstall. I change one HDD
from 18 to 73 GB. I keep size partitions and one partition add (free
space). Mirror is OK, but I have problem with silo, because when I edit
silo and run silo, silo say me:
==========================================================================================================
silo
/etc/silo.conf appears to be valid
Fatal error: In order to install SILO you must start at least one
partition on cylinder
0. Consider setting /dev/sdb3 as WHOLE_DISK (starting at 0 and ending at
disk end)
and /dev/sdb1 starting on cylinder 0 (both will make your life easier)
OS booted just from 18 GB HDD, because write silo not was successfull
==========================================================================================================
There is situatin on this server:

I search on website by google etc.
I find some advice, when it is need make label on hdd "Sun disc label"
I want make thislabel, but I make mistake. I use fdisk /dev/sda (18 GB
hdd, which booted).I want this label on /dev/sdb
I press "s" key and now I don't know which option. I finish chooce some
option and I quit fdisk by "q" key without changes write., but , when i
press
fdisk -l /dev/sda
Disk /dev/sda: 18.1 GB, 18113808896 bytes
64 heads, 32 sectors/track, 17274 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Disk /dev/sda doesn't contain a valid partition table
and when I run fdisk
fdisk /dev/sda
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF
disklabel
Building a new sun disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

Select type (? for auto, 0 for custom):
I need two advice.
1) How make correct first hdd /dev/sda, which I make problem my
mistake? This was sole boot device:( I have fear from reboot. I
think, when it is no problem, because on /dev/sda is silo and system and
data will boot from md device 73 GB hdd (in degraded mode will be md
device). But I am not sure.
2) What it is need make for change label and whole disk on /dev/sdb I
need that sparc will be booted form boath HDD.and after this I change
second 18 GB to 73.
Thank Mirek
