[gentoo-user] Swap is manually 'swapon-able' but not via fstab...?

[meino.cramer]

 Hi,

 When I do a 
 
    beagleboneblack:/root>swapon /dev/sda2  
    beagleboneblack:/root>free
                total       used       free     shared    buffers     cached
    Mem:        507476      50812     456664          0      13108      17244
    -/+ buffers/cache:      20460     487016
    Swap:      5242876          0    5242876
    

swap is added to the system.

If I add

    /dev/sda2	none		 swap  sw		                 0 0

swapspace will not be used after a reboot.

dmesg has nothing specific...

What did I wrong here? Why get swap not used via fstab?

Thank you very much for any help in advance!

Best regards,
mcc

That fstab line looks correct, only things coming to mind are wrong 
filesystem type for the partition or missing localmount from the boot 
runlevel. You can check by,

# fdisk -l /dev/sda

Look at the "Id" line, it should be "82" if I remember correctly out 
from memory.

And,

# rc-update show |grep localmount

You should see:

localmount | boot

I don't think this will help, but I hope it does :P

Do you have swap added to the boot runlevel?

# rc-update add swap boot

Hi Samuli, hi Gregory,

...the rc-update of swap was missing! Thanks a lot!
