Assign swapfile

[AllanPen]

I have F7 on another partition. Went back to it because I couldn't get java to work on 8. Anyways I re-installed 8 to mess with in my spare time. I controlled the partitioning and gave myself a home partition for the first time. What I forgot was to direct F8 to the existing swapfile. It shows in fstab and I tried mount -a but, it stil boots showing no swapfile. Here is fstab,
Edit: Still have F7.
LABEL=/1 / ext3 defaults 1 1
LABEL=/media/storage /media/storage ext3 defaults 1 2
LABEL=/home /home ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/sda2 swap swap defaults 0 0

Hello:
If your F7 installation is not using LVM then you should have nothing to worry about as F8 would pick that swap partiton up and use it.

From F8, what is the output of
su -
swapon -s

BTW, there is a swap denoted in the fstab file you posted above ?

/dev/sda2 swap swap defaults 0 0

Hello Seve; output zilch
[root@localhost opt]# swapon -s
Filename Type Size Used Priority

That's what I figured; that it would pick up on the existing swapfile.

Hello:
Is your F7 using LVM ?
If you created a custom partition [non-LVM] for F8 and are using LVM for F7 then you cannot share the swap.

If that's not the case and the output of
fdisk -l
shows something like
/dev/sda2 14339 14593 2048256 82 Linux swap / Solaris
and it matches what you have in your /etc/fstab file

then try
su -
swapon -a
then
swapon -s

and post the output

[root@localhost opt]# swapon -a
swapon: /dev/sda2: Invalid argument
[root@localhost opt]# swapon -s
Filename Type Size Used Priority
[root@localhost opt]#

and excerpt from fdisk -l

/dev/sdb2 11474 11664 1534207+ 82 Linux swap / Solaris

Hello:
You need to edit your /etc/fstab file and change
/dev/sda2 swap swap defaults 0 0
to
/dev/sdb2 swap swap defaults 0 0
save, exit and then
try
swapon -a
then
swapon -s

swapon -a will activate any valid swap partition from the information denoted in your /etc/fstab file and since what is now there <=> to /dev/sdb2 it's throwing out the error you posted above.

Ahh Jeez of course.
