[linux-lvm] Can't use LVM1 VG/LVs under LVM2; LV xxx: inconsistent LE count 32 != 64

[linux-lvm] Can't use LVM1 VG/LVs under LVM2; LV xxx: inconsistent LE count 32 != 64

[Jesse Molina]

I'm having a problem getting a Debian system from Linux kernel 2.4 to 
2.6 due to LVM.  On the 2.4 kernel/LVM1, the VGs and LVs work fine, 
mount up, and show absolutely no sign of any problem.  However, I can't 
get the 2.6 kernel/LVM2 to activate the VGs at all.

I've filed a Debian bug, which has additional information, here;
	http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=422963



The interesting error messages under 2.6 include;

	"LV tmp: inconsistent LE count 32 != 64"
	
	"System ID sorrows1107837513 on /dev/sdd3 differs from 
sorrows1107837515 for volume group"

Notice how the LE count is about half of what it should be (reports 32, 
but is actually 64).  These LVs are striped across the two disks, thus 
two 32 LE stripes in each PV that make up the VG upon which this LV exists.

Bad error checking, or actual problem?  I don't know.



This person seems to have had the same problem, though he had four stripes;
	http://www.redhat.com/archives/linux-lvm/2006-October/msg00109.html

I originally reported this problem roughly eight months ago, with no 
resolution or response;
	http://www.redhat.com/archives/linux-lvm/2006-September/msg00010.html



Help?

You need a newer version of lvm2 (> 2.02.21). The problem has only been 
fixed recently.

Hi Jesse,

This sounds like:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=232397

This is fixed upstream in versions from v2_02_24:
- --------
/cvs/lvm2/LVM2/WHATS_NEW:
revision 1.586
date: 2007/03/15 13:38:27;  author: agk;  state: Exp;  lines: +2 -2
Try to fix reading in of lvm1 striped LVs.
There are two fixes other than improving variable names and updating
code layout etc.

The loop counter is incremented by area_len instead of area_len * stripes;

the 3rd _check_stripe parameter is no longer multiplied by number of
stripes.
- --------

Kind regards,
Bryn.

[Jesse Molina]

Thanks for the replies.  I see that Debian has a lvm2 package version 2.02.24-6 out, and I'll try to install that.  However, I'll have to force the install, as 2.4 kernels are completely dead on Debian Unstable now, due to recent versions of libc6 requiring NPTL.  Hopefully I won't get into a critical dependency problem.

[Jesse Molina]

This is confirmed as fixed.  Thanks David and Bryn for the referral to 
the fix!

I am surprised that this bug survived in the wild for so long.  I had 
unsuccessfully tried to upgrade this system several times in the last 
two years.  I had previously thought it was the funky Promise ATA 
controller in this host.

Thanks for the help.  I'll be closing Debian bug #422963 here soon.
