Comment 1 Geoff Galitz 2012-05-08 15:43:48 UTC

I forgot to add this info:

------
[root ~]# rpm -qa | grep libxml2
libxml2-devel-2.7.6-4.el6.x86_64
libxml2-2.7.6-4.el6.x86_64
libxml2-python-2.7.6-4.el6.x86_64
libxml2-static-2.7.6-4.el6.x86_64
[root ~]#


So xml libraries are installed.

Comment 2 Kaleb KEITHLEY 2012-05-08 15:49:16 UTC

He's using the Fedora EPEL build. I get the same error in the Fedora F16 build. Not sure if this is a Fedora build/packaging problem.

Comment 3 Kaleb KEITHLEY 2012-05-09 17:49:20 UTC

Please try the new epel builds at https://koji.fedoraproject.org/koji/buildinfo?buildID=318151 and see if they resolve the issue.

Thanks,

Unfortunately it did not work:

Comment 5 Kaleb KEITHLEY 2012-05-10 12:24:07 UTC

That's strange.

On both my f16 and rhel6 boxes after upgrading to the respective 3.2.6-2 builds, here's what I get:

% gluster volume set help-xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<options><option><defaultValue>16</defaultValue><description>...
...

% rpm -qa | egrep glust
glusterfs-server-3.2.6-2.el6.x86_64
glusterfs-3.2.6-2.el6.x86_64
glusterfs-fuse-3.2.6-2.el6.x86_64

The message: "Error: xml libraries not present to produce xml-output" is the result when libxml2-devel (and libxml2) are not being present on the build system when the configure script is run. It's only the mgmt xlator that's linked with libxml2.so, thus:

% ldd /usr/lib64/glusterfs/3.2.6/xlator/mgmt/glusterd.so
	linux-vdso.so.1 =>  (0x00007fff337ff000)
	libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x00007fa7d048e000)
        ...

Comment 6 Geoff Galitz 2012-05-10 15:02:58 UTC

My output:

[root ~]# gluster volume set help-xml
Error: xml libraries not present to produce xml-output
Set volume unsuccessful

[root ~]# rpm -qa | egrep gluster
glustermg-backend-1.0.0alpha-1.x86_64
glusterfs-fuse-3.2.6-2.el6.x86_64
glusterfs-3.2.6-2.el6.x86_64
glusterfs-server-3.2.6-2.el6.x86_64

[root ~]#  ldd /usr/lib64/glusterfs/3.2.6/xlator/mgmt/glusterd.so
        linux-vdso.so.1 =>  (0x00007fff6adff000)
        libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x00007ff7658ee000)
        libgfxdr.so.0 => /usr/lib64/libgfxdr.so.0 (0x00007ff7656d9000)


So the libs are there... but it does not work.

Comment 7 Anand Avati 2012-05-10 23:33:52 UTC

CHANGE: http://review.gluster.com/3305 (glusterfs.spec.in, Add BuildRequires: libxml2-devel so that configure will DTRT on Fedora's Koji build system) merged in master by Anand Avati (avati)

Comment 8 Kaleb KEITHLEY 2012-05-16 14:42:34 UTC

I installed CentOS 6.1 as a kvm guest (/etc/centos-release says 6.2. Huh?)
Added epel repo. Installed glusterfs-3.2.6-1, get the error. 
Then yum localupdate to 3.2.6-2-el6; no longer get the error.

% cat /etc/centos-release
CentOS release 6.2 (Final)

% rpm -qa | egrep glusterfs
glusterfs-3.2.6-2.el6.x86_64
glusterfs-fuse-3.2.6-2.el6.x86_64
glusterfs-server-3.2.6-2.el6.x86_64

% ldd /usr/lib64/glusterfs/3.2.6/xlator/mgmt/glusterd.so 	
	linux-vdso.so.1 =>  (0x00007fffa51cf000)
	libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x00007fe509ee6000)
	libgfxdr.so.0 => /usr/lib64/libgfxdr.so.0 (0x00007fe509cd1000)
	...

% gluster volume set help-xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<options><option><defaultValue>16</defaultValue>...

As much as it pains me to do it, I have to say: works for me.

Comment 9 Geoff Galitz 2012-05-17 08:37:23 UTC

Well...  it doesn't work for me.  :)

I do see this in the logs when I try the volume set help-xml command:
