Description of problem: I tried to execute the case mentioned in BZ 1220999, this is about exporting a volume when selinux is enforced Now, the case is tried with selinux enforced. I tried to export the volume manually, using dbus commands. This is successful done. Now, I tried to unexport the volume and it fails, a coredump for nfs-ganesha is generated. Version-Release number of selected component (if applicable): glusterfs-3.7.0-3.el6rhs.x86_64 nfs-ganesha-gluster-2.2.0-2.el6rhs.x86_64 How reproducible: always Steps to Reproduce: 1.unexport the volume manually using the command, dbus-send --print-reply --system --dest=org.ganesha.nfsd /org/ganesha/nfsd/ExportMgr org.ganesha.nfsd.exportmgr.RemoveExport uint16:1 Actual results: step1, core generated, bt, #0 0x00007f3f554e1e7b in export_release () from /usr/lib64/ganesha/libfsalgluster.so.4.2.0 Missing separate debuginfos, use: debuginfo-install dbus-libs-1.2.24-8.el6_6.x86_64 glibc-2.12-1.166.el6.x86_64 keyutils-libs-1.4-5.el6.x86_64 krb5-libs-1.10.3-42.el6.x86_64 libacl-2.2.49-6.el6.x86_64 libattr-2.4.44-7.el6.x86_64 libblkid-2.17.2-12.18.el6.x86_64 libcap-2.16-5.5.el6.x86_64 libcom_err-1.41.12-21.el6.x86_64 libselinux-2.0.94-5.8.el6.x86_64 libuuid-2.17.2-12.18.el6.x86_64 nfs-utils-lib-1.1.5-11.el6.x86_64 openssl-1.0.1e-39.el6.x86_64 zlib-1.2.3-29.el6.x86_64 (gdb) (gdb) (gdb) bt #0 0x00007f3f554e1e7b in export_release () from /usr/lib64/ganesha/libfsalgluster.so.4.2.0 #1 0x0000000000508578 in free_export_resources () #2 0x000000000051a2cd in free_export () #3 0x000000000051b759 in put_gsh_export () #4 0x000000000051c8f1 in gsh_export_removeexport () #5 0x000000000052ed50 in dbus_message_entrypoint () #6 0x0000003c5e41cefe in ??

Updated the setup based on recommendations given in, https://bugzilla.redhat.com/show_bug.cgi?id=1220999#c9 I tried to unexport a volume using the cli i.e. gluster volume set <volname> ganesha.enable off and the unexport still fails.
We have a fix for this issue - https://review.gerrithub.io/#/c/236129/ Will include this fix in the next NFS-Ganesha RPM build
