swapon read swap header failed

[Basil Gello]

Binary package hint: util-linux

my test system can not mount swap at startup. Doing a swapon -a gives an error "read swap header failed: invalid argument"

Could you run "sudo blkid" and attach the output, along with your /etc/fstab

sudo blkid:

/etc/fstab:

Curious, that finds the header just fine - I guess your swap has been corrupted by a bad hibernation or something.

Could you try:

sudo mkswap /dev/sdb3

And then reboot - does the error go away?

Scott,

two days ago I have got an update of mountall package from a repo and everything worked fine! Thank you for reply, the bug is closed!
