swap not activated after choosing 'use whole disk' with encrypted home

Bug #986806 reported by Redmar on 2012-04-22

ubiquity (Ubuntu)

Bug Description

I already had 12.04 installed on this pc, so for partitioning I choose "remove and reinstall Ubuntu 12.04".
I choose to install with encrypted home, which means the swap also got encrypted. Installation went fine, but afterwards ubuntu did not recognise the swap partition.

So I just tried to reproduce this bug but couldn't.

I installed Ubuntu 12.04 desktop i386 in English and selected encrypted home, checked post-install that the swap was encrypted and active. Then I did another Ubuntu 12.04 desktop i386 in English with encrypted home on top of it and still had encrypted swap enabled post-install.

Were you indeed replacing an existing 12.04 install or was it an 11.10 install you replaced?

Also, can you reproduce this somewhat reliably or was it just a one-time thing? If you can reproduce it, can you attach /var/log/installer/syslog from the first and second install please?


Stéphane Graber (stgraber) wrote :

Actually, I just found a clue that low-memory might be the cause as you're installing with < 512MB of RAM. Doing another test install here.

Stéphane Graber (stgraber) wrote :

Right, so installing with 480MB gives me a similar log as yours but I still get an encrypted swap. Now doing another install on top of it to see if that triggers it.

Stéphane Graber (stgraber) wrote :

Second install finished, still have an encrypted swap post-reboot, so it doesn't seem to be as easy to reproduce as it sounds.

Unless we can get a clear reproducer, we'll consider this a random issue and not a release critical bug requiring immediate investigation and fixing.

If someone can reproduce this, please attach /var/log/installer/syslog, /etc/fstab, /etc/crypttab, /var/log/syslog and a tarball of /var/log/upstart from both installs, that should help understand precisely what's going on here.

I can reproduce this issue, I've taken the following steps to obtain the requested log files.
1) Wipe the whole drive of the laptop
2) Wipe the bootable usb and put the image on it using usb-creator-gtk (don't allocated any room to store files)
3) Boot the laptop from the usb, and press any key during initial booting to go to the menu
4) Select language "Nederlands", press F6 and choose "Alleen vrije software" (free software only).
5) Choose "Try ubuntu without installing". Double click the install button once the desktop is loaded
6) Choose "Erase and use full disk" in the partitioning window
7) Select "Encrypt my home dir" when settin up the account
8) Reboot the system, swap is not activated. See the attached logfiles

This affects me too. After installing a fresh installation of 12.04 (yesterday daily ISO) with encrypted home (which is causing the swap being encrypted too) this randomly happens. When i checked yesterday the swap was activated but today it wasn't. My RAM is 2GB and the swap is about 3,7 GB.

Stéphane Graber (stgraber) wrote :

Redmar: Does it magically fix itself after a few reboots for you?

The files you attached show that everything has been configured properly by ubiquity, though there may be some kind of race at boot time.

Can you also attach the output of "sudo parted -l" and /var/log/boot.log?

Stéphane Graber (stgraber) wrote :

Also, what happens if you run "sudo swapon /dev/mapper/cryptswap1"?

Redmar (redmar) wrote :

I have rebooted 8 times now, and every time there is no swap. /dev/mapper/ only containts 'control' after each boot.

This is very annoying, knowing that it's tomorrow gold release comes out. I have rebooted or started the computer four times and for one of them the swap has being activated. The other not. I know that my version (21/4 daily ISO) is beta but it's nearly finished. How can i activate swap without disable cryptswap? Trying to enable swap with the command sudo swapon /dev/mapper/cryptswap1 can't be done because the file /dev/mapper/cryptswap1 doesn't exist if the swap hasn't been activated at first. Attach some logs. Hope it can be fixed. :)

I've booted the computer two more times and no swap. I haven't changed anything. I'm thinking of disable the encrypted swap if i can't find any solution. But that's not a good solution either. So what can i do?

My swap is not on either. /dev/mapper/cryptswap1 missing.
Tried to swapon /dev/sda5 (the swap partition) and it failed too.
Running out of memory on my 1GB Pentium 4 HT. Need this fixed please.

I deactivated my encrypted swap. I was in need of the swap like you. This is very annoying.

pelm (pelle-ekh) wrote :

This is an annoying yet proceeding problem on my 12.04 system. Swap activated at random time. Reinstalled my system for other things some time ago, selected encrypted home when i installed, the swap gets activated most boots but today again it isn't active. It's very annoying. So now i'm going to deactivate the encrypted swap again. ):

summary: - swap not activated after choosing 'use whole disk'
+ swap not activated after choosing 'use whole disk' with encrypted home

As Stéphane, I couldn't reproduce this.

With 'use entire disk' and encrypted home, on boot I sometimes have the message:
'cryptswap1' is not ready yet or not present
Continue to wait; or Press S to skip mounting or M for manual recovery

If I wait a few seconds, boot continues and swap is activated. I verified upon login that /dev/mapper/cryptswap1 exists and 'free' shows the swap area.

One more strange thing: during the install the pc sees the usb drive I use to install as /dev/sda, so I have to install the system and grub to /dev/sdb. Could this be related to the problem?

I tried reproducing the bug with Quantal running on VirtualBox with disk space 10.7GB .
jibel's words echo exactly what I experienced.
While rebooting it said,

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

Within a minute system rebboted without any error.
On booting, like you suggested, I executed "free -m"
The result is:

Honestly, I didn't understand that.
