maxswapchunks
Hi,
One of my server has popup the following message. What is this mean?
vmunix: Unable to add all file system swap from: /tmp/paging. Increase the tunable parameter maxswapchunks by 1 and re-configure your system.
Actually I have seen this message popup two days ago but I just ignore it. Currently my maxswapchunks kernel parameter is 384 and my swap filesytem is 768MB.

Re: maxswapchunks
Hi,
The maximum configurable swap is dependent on a kernel parameter called maxswapchunks
The maximum swap space in bytes is:
maxswapchunks ? swchunk ? DEV_BSIZE
(Normally swchunk=2048 and DEV_BSIZE is 1024 bytes)
In your case
maximum swap space that can be configured would be 768MB
And looks like you are trying to add more filesystem swap and since you have already configured the maximum swap you are getting the error.
To add more swap you will need to increase the kernel parameter maxswapchunk.
-HTH

They think they know but don't. At least I know I don't know - Socrates

Re: maxswapchunks
Hi,
What this message actually means is that your
system is attempting to use swap space that
has been created, but the limit in your kernel
prevents it from being actually used.
The message indicates that you have filesystem
swap. It would be far better to use pseudo swap
and not swap that resides on an actual mount point.
To increase your maxswapchunks kernel parameter, you can use 'sam'. I suggest you increase this to a minimum of 1024. You will need to reboot your system in order to do this.
sam --> kernel configuration --> configurable
parameters -->

Re: maxswapchunks
Hi ,
When you try to add more swap space which is out of the reach of the kernel parameter "maxswapchunks" then SAM automatically gives you the message for increasing the parameter value. The maximum value for maxswapchunks inHPUX 11.0 is 16384.
Once you have rebiult the kernel after changing this paramter then only you can enable the secondary swap you are trying to create.
Hope this helps..
Cheers !!!
