[pkg-cryptsetup-devel] Bug#576186: cryptsetup: Setting up crypto device on Startup takes too long w/ ext3

[hvx at divara.de]

Package: cryptsetup
Version: 2:1.0.6-7
Severity: normal


Mounting a 250gb crypto device from /etc/mtab takes almost one minute at
startup with almost no harddrive activity. This problem startet to occur
when switching from JFS to ext3.

/etc/crypttab:
# <target name>	<source device>		<key file>	<options>
cryptofs	/dev/sda3		none
check,tries=3,cipher=aes-cbc-essiv:sha256

/var/log/boot: (see the timestamps)
Thu Apr  1 11:09:57 2010: Starting early crypto disks...cryptofs (starting).
Thu Apr  1 11:09:57 2010: Enter passphrase to unlock the disk /dev/sda3 (cryptofs): 
Thu Apr  1 11:10:50 2010: done.

In order to check whether using so much time is normal, I bought another
harddisk of the same type and mirrored my system to this new disk using
the "dd" command. Mounting this disk (via usb) when the system is
startet up already takes less then 2 seconds. 

Therefore i believe that some bug is causing cryptsetup to wait 50
seconds before doing something sensible.
