thanks in advance ...
Unable to add all swap for device: /dev/vg01/swap3. Increase the tunable parameter maxswapchunks by 1256 and re-configure your system.
Regards.
Solved! Go to Solution.

Re: Increase the tunable parameter maxswapchunks
It would seem you have extended swap beyond the capacity with the current maxswapchunks setting.
Quick fix is to use sam to set the parameter higher. You will then need to reboot the system to make the change to swap active.

SolutionI also suggest you not use forumulas to calcuate this value. Use sam to override the forumula and plug in your needed value.

Re: Increase the tunable parameter maxswapchunks
This is straighforward. Choose a value for 'maxswapchunks' that is at least 1256 larger than your current value.
I prefer an integer number of 256 increments up to a maximum value of 16,384.
You can consult the 11.0 kernel tuning document for an understanding of this parameter. It applies well enough to 10.20 in this case:
