cryptswap1 not ready or not present

[rbscairns]

I recently had need to reinstall Ubuntu 12.04, this time encrypting my hard disk. Since then, before the login screen appears, I get the following message:

The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present.
Continue to wait or Press S to stop mounting or M for manual recovery.

If I wait, the log-in screen appears and I log in as normal.

If I press S, there is a wait and then the log-in screen appears and I log in as normal.

If I press M, there is a wait and then the log-in screen appears and I log in as normal.

This happens every time I start my computer.

Any ideas on what all this means?

I often got that message on 12.04. I found an article about it that said it was a timing issue. I would wait for the message to go away, which only took a few seconds, and the swap partition got mounted properly, so it seemed harmless.

After booting, you can check whether the swap is mounted correctly:

$ swapon -s
Filename				Type		Size	Used	Priority
/dev/mapper/cryptswap1                  partition	2096444	603520	-1

I think you might be right. After logging in, I am getting:

$ swapon -s
Filename				Type		Size	Used	Priority
/dev/mapper/cryptswap1                  partition	1038332	9280	-1

I will do some more research and see if I can make the message not appear.

Here is what I did to stop the message appearing:

Using

sudo gedit /etc/fstab

I changed the line

/dev/mapper/cryptswap1 none swap sw 0 0

to read

/dev/mapper/cryptswap1 none swap sw,noauto 0 0

I then used

sudo gedit /etc/rc.local

and immediately before

exit 0

added these two lines:

sleep 5
swapon /dev/mapper/cryptswap1

Upon re-booting, I do not get the message and swapon -s returns:

$ swapon -s
Filename				Type		Size	Used	Priority
/dev/mapper/cryptswap1                  partition	1038332	0	-1

Everything is looking good (I think).

Thanks for posting your solution. I may try it in 12.04, since I noticed that I still get the warning message.

I use Xubuntu Raring Ringtail 13.04 and I got the same message

The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present.
Continue to wait or Press S to stop mounting or M for manual recovery.

The swap seems to be mounted correctly:

~$ swapon -s
Filename Type Size Used Priority
/dev/mapper/cryptswap1 partition 1023996 68 -1

Do you think I can fix the problem like you did?
Thanks
