libvirt_storage_backend_rbd.so报错处理

2019年1月15日 发表评论 阅读评论

手欠把自用的一台宿主机的OS进行yum update 升级,升级的同时kvm也进行了升级。升级后,发现虚拟化服务libvirtd启不来了,报错:error : virModuleLoadFile:53 : internal error: Failed to load module '/usr/lib64/libvirt/storag  e-backend/libvirt_storage_backend_rbd.so': /usr/lib64/libvirt/storage-backend/libvirt_storage_backend_rbd.so: undefined symbol: rbd_diff_iterate2 。把libvirtd相关的包删除再重装,问题依旧。其报错信息如下:

放狗(google)搜索了下,发现是红帽的bug https://bugzilla.redhat.com/show_bug.cgi?id=1658652 ,红帽在 https://access.redhat.com/solutions/3746691 页面(需红帽帐号)给出了原因和解决方案。

问题原因:older version of libvirt-daemon-driver-storage-rbd usually used in older RHEL 7.x version which is missing the librbd1 dependency。(动态链接库缺失)

具体可以通过如下方法查看:

[root@rhvh42 storage-backend]# file libvirt_storage_backend_rbd.so
libvirt_storage_backend_rbd.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=f0289019f4ff9a0c87c47c928457be3672448e47, stripped

缺失的链接库文件在librbd1包里,解决方法如下:

yum update librbd1
systemctl restart libvirtd
