Remove Swap Space

[Ralf Buchhold]

Hello
can I remove a "used" swap space.
Here: /dev/vg01/lvswap2
Look at:
Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 4096 0 4096 0% 0 - 1 /dev/vg00/lvol2
dev 7000 238 6762 3% 0 - 0 /dev/vg01/lvswap2
dev 7000 0 7000 0% 0 - 0 /dev/vg12/lvswap3
reserve - 5680 -5680
memory 4612 2766 1846 60%

Thanks
Ralf

what makes you to remove the swap space?? What is the RAM you have on your machine??

In case you want to remove it, you can just comment/remove the entry for it in /etc/fstab, update the kernel parameters - maxswapchunks (which are related to define the swap space configured on your machine)

In case you do not want to removeit, you just lower the priority of that space and it will be used last.

Yes you can - but unfortunately, this requires a reboot (1 of the few knocks against HPUX).

Either comment it out from fstab, reboot, then lvremove - or just use SAM.

Even if the swapspace were "unused", your only option is a reboot. You need to edit /etc/fstab and remove the additional swap entries and then reboot.

Hi,

You have to reboot the system as it's related to kernel and it changes the kernel defination once you remove it. So you need to reboot to change reconsider the kernel on the system.
