Problems enabling swap

I just booted and noticed swap failed on bootup.

Opened a console, changed to root and tried:

[root@myhost ~]# swapon -a
swapon: /dev/hda2: Invalid argument
[root@myhost ~]#

dmesg tells me:

Unable to find swap-space signature

I've never had anything like this in my time with linux.

Absolutely nothing has changed since last boot, and it was cleanly shut down.

Any ideas?

Re: Problems enabling swap

After a bit of googling, I've re-prepared it with mkswap, but I'm curious as to why it suddenly wasn't recognised.

Any reason(s) this might happen that anybody knows about?

Thanks

Harddrive failure ?

Do you have smart on in the bios ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?

I'd have to check that.

There doesn't appear to be other issues with any other partitions though.  I'll do a manual fsck to see if that shows anything up.

Well, it happens a lot if you experiment with software suspend etc.
Another unqualified guess is that the swap partition could have been uncleanly "unmounted".

Re: Problems enabling swap

Ah!

I did try the 'lock & suspend' on the KDE applet (it's a laptop).  It did come back (seemingly) ok though   :?

When I had Ubuntu on this (Gnome) the suspend worked perfectly.
