The libdevmapper-event-lvm2snapshot.so.2.02 should link to lvm2cmd.so, where lvm2_run can be found. It doesn't ;(

Thanks for reporting this, I'm working on it now.

As a workaround for now, if you are in a hurry, I think you can use the LD_PRELOAD trick to load /lib64/liblvm2cmd.so.

FWIW, The same happens on my 32bit system:

I have created the link, I tried the LD_PRELOAD trick and last I installed the version lvm2-2.02.45-15.1.x86_64 but nothing works. The scary messages are still remaining. Also the link is not created during installation of the a.m. version.

It's not about creating symbolic link from liblvm2cmd.so to libdevmapper-event.so,
but linking liblvm2cmd.so with libdevmapper-event.so while compiling the package.
Sorry about the confusion.

Have you checked the changelog of lvm2? (using rpm -q --changelog lvm2).
I'm not sure about the version number.

em. That's strange indeed. I got no error on my side.
Would you please copy/paste the erorr message here again ?
And also a result of 'ldd /lib/liblvm2cmd.so' is very helpful.

Thanks.

I am seeing exactly the same problem. I would like to try the latest RPM, but am having no success locating it. Could someone please explain where this latest version from the build service can be located, please?

The latest version I can locate anywhere from the OpenSUSE website is:
 lvm2-2.02.45-11.1
which is dated  Mon Oct 19 21:21:46 2009. So it's obviously not the version in question.

When I search via the page http://software.opensuse.org/search, which it titled "Get Software from the openSUSE Build Service", this is the latest version found. It's also the latest version found by the normal YaST online update service.

Have this bug too. My backup routine relies on lvm snapshots.

Not sure about the answer by reading this threat: Is there any workaround for this one?

Is there any working rpm somewhere?

Thank you.

I would like a fix for this as well, although it seems cosmetic.

lvm2-2.02.45-11.1 does not fix it and I cannot find a more recent version.

I think, that this is not cosmetic. At the same time as i noticed these errors, i noticed, that lvm operations work sometimes and sometimes not. I filed a bug 581590 for that. Please vote for this bug, it is killing my backup scripts.

Yes. It's definitely not cosmetic.

I have found out it's some problem with build service(The local build with the source works,
while the 'osc build' command produce the problematic package).

Trying to fix this now.

FYI.

Hi all,

  I submitted a update into Base:System days ago. It should be ready for download and test now.
Any one can test on your side and give some feedback on this ?

  Thank you.

Could you be a little less cryptic about its location, please? If I could find it, I'd test it (the Internet is quite large...)

The only location I can think of which might relate to "Base:System" is:
http://download.opensuse.org/repositories/Base:/System/openSUSE_11.2
but there is no sign of any lvm2 package in there.

I do see a package in openSUSE_Factory, but it was my understanding that that is for pre-release 11.3 packages, and if I 'rpm -i --test' the lvm2 package in there it won't install because of failed dependencies.

Hi,
I installed this. The scary messages are gone. A (simple) test shows that it now works as expected.

@Nigel: The rpm can be found in the factory tree of Base:System

Thanks

Yes, I know that an rpm can be found in the factory tree. I said that in my post. But as I also explained, that rpm won't install in 11.2 because of failed dependencies. Presumably because the factory tree is 11.3 pre-release.

What's needed is a patch/update for 11.2, since this bug is posted against 11.2.

Install of said rpm via "zypper in" worked for me - no failed dependencies.

And the messages are gone, BTW.

How have you configured the repo in zypper? I cannot get zypper to recognize the Base:System factory at all. 

I can install from http://download.opensuse.org/factory/repo/oss/, but that lvm2 package (2.02.45-15.7) still has the same problem.

(In reply to comment #20)

Simple: I did not. I just used "zypper in http://download.opensuse.org/repositories/Base:/System/openSUSE_Factory/x86_64/lvm2-2.02.45-43.1.x86_64.rpm"

"factory" meant "openSUSE_Factory", not the one you tried.

If you absolutely want to configure the repository, you'd have to use this URL, I suppose:

http://download.opensuse.org/repositories/Base:/System/openSUSE_Factory/

Why is the corrected package not been in the stable branch 
http://download.opensuse.org/repositories/Base:/System/openSUSE_11.2/x86_64/

?

Not every production server are allowed to use "factory" rpm .

Can we expect the fix in 11.2 updates some day? Is there anything missing?

(In reply to comment #24)

I've submit a request against 11.2.
Not sure when the update will be released yet.

Thanks.

after applying this lvm2 package, I first get an error telling me that device-mapper should be updated too (because some symbol is missing in a .so, sorry, have already closed the window) so that the version of this package or this .so should be added as a requirement to the lvm2 package.

After having upgraded both, I get

event registration failed: 31418:3 libdevmapper-event-lvm2snapshot.so.2.02 dlopen failed: /lib/liblvm2cmd.so.2.02: undefined symbol: dm_udev_set_sync_support

so unfortunately there is another thing missing...

It would be kind if this could be fixed before making it official

It is correct that the now-current version lvm2.0.67-something does not work any more, whereas the then-current 2.0.45-something did. So it seems, the once-working fix isn't available any more.

This bug seems to be treated like an orphan. Considering how old it is and that a fix is (or at least was) available, it is disappointing see that we may more likely expect 11.3 released than a fix for 11.2.

The version in Base:System now is prepared for 11.3 now.
It cannot work with 11.2. Sorry.

I'm trying to figure out how to make any update for 11.2. still.

For openSUSE +1 (for an update)

would be fine by me. +1

This is a build service specific issue. I'm very sorry that this 
regression was skipped during RC phase.

I've just submit an package into Base:System to fix this.
Would you try that first ?
Meanwhile, I'll provide another maintenance update for 11.3 asap.

Thank you for bring this up and sorry for the inconvenient.

Hi Xin,
you submitted a package for device mapper. Planned was an update for lvm2.

Is an update of package device-mapper enough?

If it is not fixed in 11.3, be so kind and submit also an update for it.

Is sle also affected?

LVM2 and device-mapper share the same source code, 
but still we need an update for LVM2 here.

As far as I tested, SLE is not affected.

Thanks.

YES. Be so kind :-)
I will change the patchinfo.

Oh, sorry. There was no submission from the packager for 11.3 and then it goes under.
