Tested with the private build provided as below: [root@dhcp43-116 exports]# rpm -qa|grep ganesha glusterfs-ganesha-3.8.3-0.6.git7956718.el7.centos.x86_64 nfs-ganesha-gluster-2.4-0.rc4.el7.centos.x86_64 nfs-ganesha-debuginfo-2.4-0.rc4.el7.centos.x86_64 nfs-ganesha-2.4-0.rc4.el7.centos.x86_64 and during basic testing i don't see any ganesha crash/segfault with multiple export/unexport. Will keep continuing with the testing and update the bug if we see any issues later. Since this bug was not seen with latest upstream testing, closing it. |
