Description Richard W.M. Jones 2014-05-12 08:00:11 UTC

Description of problem:

A very common problem when upgrading qemu is this error:

qemu-system-arm: symbol lookup error: qemu-system-arm: undefined symbol:      
glfs_zerofill

It is caused because the gluster library doesn't version
symbols, and this means RPM is unable to notice that
(eg) glfs_zerofill requires a particular version of the
library.

Version-Release number of selected component (if applicable):

glusterfs, all versions in Fedora

How reproducible:

100%

Steps to Reproduce:
1. Install Fedora 20.
2. Install qemu.
3. Install fedora-release-rawhide.
4. yum --enablerepo=rawhide install qemu-system-x86
5. Run: qemu-system-x86

Actual results:

qemu (or any program linked to gluster) will fail with an
error similar to the one given above.

Expected results:

If symbols are versioned, RPM will be able to detect that
glusterfs-api/-libs needs to be upgraded at the same time as qemu.

Additional info:

A similar problem was found in ceph, see:

(I believe that bug was fixed, although the bug status doesn't
show it.)

versioned libgfapi.so is coming in 3.6.

Comment 3 Richard W.M. Jones 2014-05-12 13:27:44 UTC

Since this is (or will be) upstream, setting the resolution appropriately.

Comment 4 Richard W.M. Jones 2014-05-24 06:43:05 UTC

*** Bug 1100929 has been marked as a duplicate of this bug. ***

Comment 5 Helmut Schlattl 2014-05-26 17:59:44 UTC

The same error occurs now also on a pure Fedora-20 installation:

qemu-system-x86-1.6.2-5.fc20.x86_64
glusterfs-api-3.5.0-3.fc20.x86_64

So it is not pure upstream. Versioned libgfapi.so is also required in F20. Reopen?

Current Workaround: downgrade qemu-system-...
