I'm getting a failure duing boot:
Activating swap patition: /dev/sdb1 no such device or address

System runs fine, but if this means the entire swap partition isn't coming online, I'm sure problems will arise. After boot, I looked in /dev and sdb1 is there. Not sure whats going on here.

Thanks

send the output of
swapon -a
and
swapon /dev/sdb1

also what does cfdisk or fdisk -l read about that partition?
did you do anything to it?

man swapon
man swapoff
man cfdisk
man fdisk

I actually have two identical systems in which one had a motherboard failure. In testing, I swapped some of the hardware, and may have paired up the second SCSI disk incorrectly (can't remember exactly - I was more concerned with the primary disk). They were both partitioned the same way, though. Short of reinstalling, what can I do? Here is the output of the commands you requested. Thanks!!

[root@NueMDLinux2 root]# swapon -a

[root@NueMDLinux2 root]# swapon /dev/sdb1

[root@NueMDLinux2 root]# cfdisk
bash: cfdisk: command not found

Disk /dev/sdb doesn't contain a valid partition table

was there needed data on the second drive?

if both disks were partitioned the same, you had a 1 gig swap partition + 8 gig data partition on sdb ? correct

what tools does your distro come with for harddrive maintenence?

is the data on sda1 and sda2 still good?

it sounds like something is or was hooked up wrong, or your partitrion table got messed up.

There was no data on the second drive: it only contained the swap partition. Data on sda1 and sda2 is still good - system runs fine!

When I said the partitions were the same, I was referring to both SYSTEMS having the same partitioning, ie. system/data on first drive, swap on second drive.

Its sounding like I just need to repartition the second drive, and put a swap partition on it. I'm not sure which utility is included with RH9 to do this - any suggestions?

After I set up the swap partition, is there anything I need to do to tell the system where it is, how to mount it, etc?

Thanks

man cfdisk
the swappartition is not there,
it would be easy to learn the mkswap, swapon, swapoff, fstab commands
check the man pages on the above, which explain in detail how to do it
your second drive doesn't appear to conatain anything,

also, why not use the room on the second drive? it says it's a 9gb drive, and your swap really only needs to be twice the amount of ram if that, unless you need more, but that still leaves problably 8gigs of usable space..

cfdisk should be the esiest tool, it's a text menu interface, but easy to use/.. redhat may have a graphical version..
