I have problems with lvm2 and the 2.5.73-mm2 patchset. I have two volume
groups, one with 4 lv's (lvm2 metadata) the other one with only one lv
(lvm2, too). When I boot the 2.5.73 stock kernel everything seems to be
fine, however when I boot into -mm2 only the first lv of the first vg is
found. A subsequent lvscan doesn't find anything.  I've seen this bug a
couple of kernel releases ago in your tree (I think it was
2.5.69-mmsomething) but I didn't had time to look into it then, I had
other 2.5 problems back then.  There are more things in my lvm
configuration (some pv's beeing md devices) but I don't think that is
important, since the raid stuff comes up properly. 
Booting into stock 2.5.73 brings up the lv's as expected.

I'm running debian testing on x86 with the lvm2 package installed.
LVM version:     1.95.15 (2003-01-10)
Library version: 0.96.07-ioctl-cvs (2002-11-21)
Driver version:  1.0.6

If you need more infos or patches to be tested I'd be happy to help.

Could be because -mm uses a 64-bit dev_t.

Could you please revert 
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.5/2.5.73/2.5.73-mm2/broken-out/64-bit-dev_t-kdev_t.patch
and retest?

I think there's a version of devicemapper userspace which works correctly
with 64-bit dev_t.  Perhaps the Sistina team can shed some light.

yes, reverting this patch fixes the problem. Is it sane to run the -mm2
without this patch?

would be nice if somebody else could comment on this..

Yes, I think it's the 64bit dev_t.  You'll have to wait for the new
ioctl interface + userland tools before dm can make this transition.
We've been having some problems with the tools, which caused this
delay in fixing things.  I *hope* the tools will be released this
week.

ah okay, tell me if you want me to test them, I'd be glad to do help.

Simply recompiling libdevmapper against the 2.5.7#-mm# kernel headers
helps for now.

But the plan for the future is that the dm ioctl interface will use 64
bit by default, so that it will work with any kernel version.
