[gentoo-user] System unusable after updating lvm

[lgouv]

After updating  lvm2 from 2.02.02 to 2.02.03, the system mount / which
is on a primary partition but frefus to mount /usr,/var,/home and /tmp.
On the console I see: 
Setting up the logical volume manager
Volume group for uuid not found: m6reV.........(four times)
Any idea?
Thanks

Happened to me too. I had to boot from livecd to copy lvm and some
libs to get it up again. (I used ldd lvm to see which libs i needed
also).

Hm, did yo note the following warning?

WARN: postinst
An old version of an installed library was detected on your system.
In order to avoid breaking packages that link against it, this older version
is not being removed.  In order to make full use of this newer version,
you will need to execute the following command:
   revdep-rebuild --library libdevmapper.so.1.01

After doing that, you can safely remove /lib/libdevmapper.so.1.01
Note: 'emerge gentoolkit' to get revdep-rebuild

I didn't get this warning, because I have version 1.02 of this library,
but I still ended up with a broken system. My root partition was fine
(Thank $DEITY I tried this on my laptop first) so I could untar the
package from the previous version (the ebuild had been removed from
portage). I got lots of errors about UUIDs with the new version.

There's now a further update to lvm2 and device-mapper in portage, so I'll
see what happens this time.

No, I did not. And I don't think I did get that warning.

$grep revdep-rebuild /var/log/portage/*lvm*

... nothing.

And I don't have libdevmapper.so.1.01 I have /lib/libdevmapper.so.1.02

Hi,
Something's wrong here, on boot i too receive some messages while
mounting/activating LVMs, but they mount OK.
Checking saw i have both /lib/libdevmapper.so.1.01 and
/lib/libdevmapper.so.1.02. Both belong to "device-mapper":
# qfile /lib/libdevmapper.so.1.01
sys-fs/device-mapper (/lib/libdevmapper.so.1.01)
# qfile /lib/libdevmapper.so.1.02
sys-fs/device-mapper (/lib/libdevmapper.so.1.02)
The sizes are *different* the times are equal:
# ls -l /lib/libdevmapper.so.1.01
- -r-xr-xr-x 1 root root 25056 2006-03-05 10:50 /lib/libdevmapper.so.1.01
# ls -l /lib/libdevmapper.so.1.02
- -r-xr-xr-x 1 root root 58036 2006-03-05 10:50 /lib/libdevmapper.so.1.02
But running "revder-rebuild" gives me nothing to rebuild:
# revdep-rebuild --ignore --library /lib/libdevmapper.so.1.01 -p vv
Configuring search environment for revdep-rebuild

The problem here seems to be that LVM2 (which is build statically, and
no static USE-flag present). sys-fs/lvm2-2.02.03
Checked - is a static binary, but must somehow be build against the
older library (code), so the said messages/warnings.
Will try rebuilding 'device-mapper' then 'lvm2' and rename the minor
version library.
Or some other app is links against the old version (reverse deps):
# dep -L device-mapper
sys-fs/device-mapper:
        app-crypt/truecrypt-4.1              >=sys-fs/device-mapper-1.00.08
        sys-fs/cryptsetup-luks-1.0.1-r2
>=sys-fs/device-mapper-1.00.07-r1
        sys-fs/lvm2-2.02.03                  >=sys-fs/device-mapper-1.02.03
...END...

I believe it has nothing to do with the device-mapper version. I already
had 1.02 before I updated lvm2 and had the same problems.

Hi,
Same here, still no fix (was to be expected, but had to try).
Now emerging 2.02.04-r1 (03, 04 are gone, 02-r1 is back) have some new
patches. Fixage is expected in 2.02.05 i assume (Changelog).

I've just emerged 2.02.04-r1 and it rebooted fine.
