swap space

[Donna Powell]

I am in the process of redoing my filesystem layout. I have two existing vg's, vg00 and vg01. I want to remove vg01 completely using vgexport, but there is a lv that was created for swap space. Is there a way to deactivate the swap space so that I can recreate this lv to used for something else. I want to put the new swap space in vg02 on lvol1

Hi Donna:

Comment the entry in /etc/fstab with a leading '#' and reboot then only your primary swap on vg00 will be active.

Donna,
There is no way to get rid of swap space without rebooting. Comment the entry out of /etc/fstab and reboot.

Good Luck,
C

Hi Donna:

While you can add swap without rebooting (assuming that you have an adequate 'maxswapchunks' kernel setting), to deactivate it you must boot. Simply remove the secondary swap specification from /etc/fstab and reboot. Afterwards you will be able to 'lvremove' the logical volume to which it was assigned.

Regrads!

Hi
To free up the swap lv, you will have to comment the entry in /etc/fstab and reboot the machine.

Thanks.
Prashant.

hi,

Since swap is used by the system dynamically, you cannot
delete it on-line.

Reboot is the only option.
But make sure that you
comment out or remove the
swap entry from the /etc/fstab file , before
you reboot. Otherwise, the
swap will get mounted/enabled
again!
