Swap disabled in 10.3 after 2.6.22.18-0.2 upgrade

Hi,

After having upgraded the kernel to 2.6.22.18-0.2 with Yast, my swap has been disabled.

Have any of you encountered this before?

Code:

frode@dhcppc2:~> free -m

I've tried various combinations of swapon and its flags to enable it again, but to no avail.

Ideas?

run fdisk -l to see the device names for the partitions. The swap should be labeled type 82. You can try your swapon commands from there. if you run mkswap on the wrong partition, you'll lose all the stuff that was in it.

Thanks for your reply. Here's the output.

Code:

dhcppc2:/dev/disk # fdisk -l

Disk /dev/sda: 60.0 GB, 60011642880 bytes
255 heads, 63 sectors/track, 7296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0004c426

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         199     1598436   82  Linux swap / Solaris
/dev/sda2   *         200        2810    20972857+  83  Linux
/dev/sda3            2811        7296    36033795   83  Linux

Looks like the id is right (82).

Works now :-) Thanks again, whansard.
