8.0-RC3 vs. geli (Problem finding encrypted partitions)

S

siffre

I have bumped into some truble when upgrading my primary computer from 7.2-RELEASE to 8.0-RC3. I'm running full disk encryption (exept for /boot, obviously) using geli. One encrypted device containing several partitions.

I'll illustrate the problem wih some output.

With the harddrive plugged into a different computer running 7.2R it all works fine:
Code: 
[B]a701# uname -a[/B]
FreeBSD a701 7.2-RELEASE-p4 FreeBSD 7.2-RELEASE-p4 #0: Fri Oct  2 12:21:39 UTC 2009  root@i386-builder.daemonology.net:/usr/obj/usr/src/sys GENERIC  i386

...

/dev/da1s1b.elia        /dev/da1s1b.elid        /dev/da1s1b.elig
Please notice all the pretty partitions. Just waiting to be mounted.

But with the same harddrive connected to a computer running 8.0-RC3, something goes bad:
Code: 
[B]ct# uname -a[/B]
FreeBSD ct 8.0-RC3 FreeBSD 8.0-RC3 #0: Tue Nov 10 07:50:36 UTC 2009 root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386
[B]ct# geli attach da0s1b[/B]
Enter passphrase:
[B]ct# dmesg[/B]
...
GEOM_ELI: Device da0s1b.eli created.
GEOM_ELI: Encryption: AES-CBC 256
GEOM_ELI:     Crypto: software
[B]ct# ls /dev/da0s1b*[/B]
/dev/da0s1b     /dev/da0s1b.eli
And that's it. The partitions inside the geli device are not found.

Having a look at the label (still at 8.0-RC3), they are there, and decryption works. So why are they not found? :(
Code: 
[B]ct# bsdlabel da0s1b.eli[/B]
# /dev/da0s1b.eli:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:   964608       16    4.2BSD     2048 16384 60296
  b:   819200   964624      swap
  c: 624732768        0    unused        0     0         # "raw" part, don't edit
  d:  1683456  1783824    4.2BSD     2048 16384 28552
  e:   880640  3467280    4.2BSD     2048 16384 55048
  f: 16384000  4347920    4.2BSD     2048 16384 28552
  g: 604000848 20731920    4.2BSD     2048 16384 28552

This means I'm very stuck after the first reboot in the upgrade process, since my root filesystem is inaccessible.

Does anybody have any suggestions to what might be causing this?
 
hmm, that's weird, I have full HDD encryption as well.
I use key only to decrypt, and I have no problems

Code: 
FreeBSD killasmurf86.pc 8.0-RC3 FreeBSD 8.0-RC3 #0: Fri Nov 13 16:14:51 EET 2009
killasmurf86@killasmurf86.pc:/usr/obj/usr/src/sys/ANTIGENERIC  i386
 
Loading geom_bsd.ko, geom_mbr.ko, and geom_label.ko,
one or more of those fixed /dev detection (more
devices found) on _8 stable.
(here anyway.)
If you can load them
before the boot ((boot> ) or something, or loader.conf,)
a chance it would help... not certain but...
 
Thanks, geom_bsd fixed it. Almost to good. I got tons of partitions now.

On 8.0-RC3:
Code: 
[B]ct# ls /dev/da0s1b*[/B]
/dev/da0s1b		/dev/da0s1b.elica	/dev/da0s1b.elid
/dev/da0s1b.eli		/dev/da0s1b.elicb	/dev/da0s1b.elie
/dev/da0s1b.elia	/dev/da0s1b.elicd	/dev/da0s1b.elie
/dev/da0s1b.elia	/dev/da0s1b.elice	/dev/da0s1b.elif
/dev/da0s1b.elib	/dev/da0s1b.elicf	/dev/da0s1b.elif
/dev/da0s1b.elib	/dev/da0s1b.elicg	/dev/da0s1b.elig
/dev/da0s1b.elic	/dev/da0s1b.elid	/dev/da0s1b.elig

With the harddrive back in the machine where it belongs, it worked fine to boot (with geom_bsd), but I was asked for a passphrase for ad4s1cb. I have no such partition. :\
Code: 
[B]asus% ls /dev/ad4*[/B]
/dev/ad4		/dev/ad4s1b.elic	/dev/ad4s1b.elie
/dev/ad4s1		/dev/ad4s1b.elica	/dev/ad4s1b.elif

  f: 16384000  4347920    4.2BSD     2048 16384 28552 
  g: 604000848 20731920    4.2BSD     2048 16384 28552
So geom_bsd seems to find the other partitions again on the 'c'-partition. How to fix that? :e

But I'm back on track with the upgrade, currently rebuilding all ports.
