Re: strange things about swap on NFS

In message [ref] you wrote:

  But I found that the "dd if=/dev/zero of=swapfile bs=1M
count=62" is not easy to executed:

This command alone should just work fine.

  The system is often no response after execute this command. On several
time, it add swap successfully.
   But  when I start to compile package. The system then no response !!

From your subject and this description I understand that you then try

to use this file as swapfile over NFS, and this causes problems.

There is a known problem with swap over NFS, at least for 2.4 kernels.

   How to slove the problem? Is the reason of my hard disk? I think not,

RTFM. A solution is described in detail at
http://www.denx.de/twiki/bin/view/DULG/SwappingOverNFS

Note that this is terribly slow, though - but sometimes  it's  better
to  have  a slow and working system than one which is fast and out of
memory.

Best regards,
