swap partition not found

[Per]

I have a swap partition on /dev/sda1 and I have this line in my /etc/fstab:

/dev/sda1 swap swap defaults 0 0

When I try to mount that partition with swapon -a I get this error message:

swapon: /dev/sda1: open failed: No such device or address

I can see the partition when i run lshw:

description: Linux swap volume
physical id: 1
bus info: scsi@0:0.0.0,1
version: 1
serial: <UUID>
size: 8189MiB
capacity: 8189MiB
capabilities: primary nofs swap initialized
configuration: filesystem=swap pagesize=4096

If I put the line "UUID=<UUID> swap swap defaults 0 0" in /etc/fstab and run swapon -a I get this error message:

swapon: cannot find the device for UUID=<UUID>

Device /dev/sda1 isn't listed when I run blkid.

Just to try another thing: Start Mandriva Control Center > Local Disks
Enable the log window: Menu alternative > Show log
Then: Remove the swap partiton, create a new, close and let it write fstab, reboot.

No change, unfortunately. I examined the lshw output again and found that there was no logical name for sda1.

What do you mean by "logical name for sda1"?

Please also show the output of

Code: Select all

cat /proc/partitions

There's no line "locigal name:" for /dev/sda in output of lshw.

Please also show the output of

Code: Select all

cat /proc/partitions

So you have no partition sda1.

Please run the following as root and post the output here:

Code: Select all

fdisk /dev/sda -l

Maybe this helps. This is how I did it in Mandriva awhile back.

I found that If I run partprobe my system sees the swap partition. As a workaround I've added the line

@reboot partprobe

to crontab.

Looking at your partition table, I recall some "very old" Linux/unix/BSD programs which did stuff based on hda[x] and I ran into trouble with 2 digit partitions, but these were back in the days like, say. Mandriva 8, 9 or 10.

Seeing that you have a partition sda10, could you perhaps reduce your partition count to sda9 and see if the problem goes away. If it does, then it may indicate that there are still some programs that may still be making use of the 1 digit variant. One way to try it out is see about turning-off sda10 if that partition isn't critical to you at the moment (just for the purpose of trying it out).
