No swap activated on kernel 2.6
 

Hi,

I compiled the kernel 2.6.4 with make oldconfig. I don't have swap:

root@Colossus:~# free -m
total used free shared buffers cached
Mem: 502 498 4 0 14 338
-/+ buffers/cache: 145 357
Swap: 0 0 0

root@Colossus:~# swapon /dev/hda4

root@Colossus:~# fdisk -l /dev/hda

root@Colossus:~# cat /etc/fstab
/dev/hda4 swap swap defaults 0 0

root@Colossus:~# grep SWAP /usr/src/linux-2.6.4/.config
CONFIG_SWAP=y

What else do I need to do to activate this damn swap ? I need it !

Thank you,

did you try : #mkswap /dev/hda4 ?
and then : #swapon -a ?

root@Colossus:~# mkswap /dev/hda4
Setting up swapspace version 1, size = 131600 kB

root@Colossus:~# swapon -a

Sigh !

maybe it's got something to do with ' make oldconfig '. you're using the .config
of your prev. ( 2.4.x ) ?. also found this : http://kerneltrap.org/node/view/2987
seems like your Q ?

i should try a 'make xconfig' with the old .config ( to start with ) and check if all swap and paging functions are enabled , and then 'make bzImage etc....

yeah, it was my question but nobody was able to solve the matter, I will try make xconfig as you suggested me.

Thank you,
