Shutdown failure and empty boot.log with encrypted system

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



My system is functioning from an encrypted root, with separate /usr, /usr/local, /var, and /home partitions also encrypted.  The system details are

intel core2duo cpu
Fedora 11 (completely up-to-date)
2.6.31-rc5-git5 from kernel.org
loop-AES-3.2g (compiled as module)
aespipe-v2.3e
util-linux-ng-2.15.1
build-initrd.sh configured USEPIVOT=2.

I have two issues:  The first is since encrypting /, the file /var/log/boot.log is no longer written.  Is this a problem with my specific setup or is this how it behaves for everyone else?

The second is that after encrypting the remaining partitions, the system will not shut down properly, hanging at the point it attempts to umount /var and /usr.  Warnings that these partitions are busy and cannot be umounted are printed to the screen and repeatedly hitting CTRL-ALT-DEL simply repeats the warning. At this point I'm unable to get to a shell prompt so I'm kind of stuck as far as live troubleshooting goes and I'm forced to power down via the On/Off button.

I don't know if it's relevant, but as written in another post, the system was unable to boot with an /etc/rc#.d/S00losetup init script forcing me to instead add the losetup commands for the additional partitions to /etc/rc.d/rc.sysinit.  The entries in fstab are as described in the loop-aes README:

/dev/sda1   /boot            ext3    defaults        1 2
/dev/loop2  /                   ext4    defaults        0 1
/dev/loop3  /home          ext4    defaults        0 2
/dev/loop5  /usr              ext4    defaults        0 2
/dev/loop6  /var              ext4    defaults        0 2
/dev/loop7  /usr/local      ext4    defaults        0 2
/dev/sda8   swap            swap    sw,loop=/dev/loop0,encryption=AES128   0 0

Ideas?  Can I provide other information that would be helpful with troubleshooting?

Also, this seems like the right place to ask, but if there is a more appropriate forum/mailing list for me to post these questions just let me know.

Thanks.
