Hi ,

Am getting this error now ,

root #/dev/vg00 >swapon -a
Enabling device paging on /dev/vg00/swap3.
swapon: Device /dev/vg00/swap3 contains a file system.
The system will page in the space after the end of the file system.
Add `end' to the options field in /etc/fstab to turn off this warning.
swapon: The kernel tunable parameter "swchunk" needs to be increased to add
paging on device /dev/vg00/swap3.

chkd swchunks value , its 4096 ..its static value..

i would be needing a reboot right ??

can i increase my swap my 4 gb...if nt 8 gb which is currently the value m trying..?
