[Bug 1153661] Re: The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present

[RavanH]

On 14.04 I tried all suggested solutions: Puny Geeks step-by-step (see
http://punygeek.blogspot.com/2012/10/ubuntu-1204-how-to-solve-disk-
drive-for.html), then again but using /dev/sda8 (swap partition in my
case) instead of UUID, then the approach with noauto parameter in fstab
and the 5 second delay in rc.local (both see
http://askubuntu.com/questions/289858/disk-drive-for-dev-mapper-
cryptswap-1-is-not-ready) but none worked cross reboots.

One thing I find striking is that now:

~$ sudo swapoff -a
~$ sudo swapon /dev/mapper/cryptswap1
swapon: /dev/mapper/cryptswap1: lezen van kop van wisselgeheugen is mislukt: Ongeldig argument

... which means something like "reading of swap header failed: Invalid
argument"...

And it turns out after all this I cannot even reformat or recreate the
swap partition in gparted. I get some kind of warning about being unable
to inform the kernel of the changes made...

Starting to regret my choice to encrypt the home partition during
install :(

  mountall 2.48 is still showing most times on booting that
  /dev/mapper/cryptswap1 is not ready.

  My system was configured on installing to use ecryptfs on my home
  partition. This is why my swap partition was automatically configured
  to be encrypted with dm-crypt.
