Openstack對接Ceph時的錯誤
本次 Openstack 版本為N版ceph版本為J版在對接volume和glance時非常輕松不過在對接nova的時候坑了一下午。
ERROR nova.compute.manager [instance: b6b53548-2d12-4019-a189-1d006455dfa3] 2017-08-07T14:09:55.209454Z qemu-system-x86_64: -drive file=rbd:vms/b6b53548-2d12-4019-a189-1d006455dfa3_disk:id=cinder:auth_supported=cephx\;none:mon_host=192.168.0.151\:6789,file.password-secret=virtio-disk0-secret0,format=raw,if=none,id=drive-virtio-disk0,cache=none: Unknown protocol ‘rbd‘
意思是說不支持rbd協議 於是乎查看自己的qemu。我的qemu是編譯安裝的詳情見
http://home.51cto.com/space/6890594
[[email protected] ~]# qemu-img --help | grep rbd [[email protected] ~]#
註此時我已經裝了ceph相關的包現在已經有了rbd的命令內核已經也已經有了rbd現在是qemu不支持rbd協議接下來繼續證明這個事情
[[email protected] ~]# rados lspools glance volumes vms rbd images [[email protected]
可以看到直接讓qemu使用ceph都不行報不支持rbd協議此時 我回想自己編譯qemu時是默認選項查了好多文檔默認是不支持rbd的所以要重新編譯此次開啟rbd
[[email protected] qemu-2.9.0]# ./configure --enable-rbd No C++ compiler available; disabling C++ specific optional code ERROR: User requested feature rados block device configure was not able to find it. Install librbd/ceph devel
報No C++我們來安裝包
[[email protected] qemu-2.9.0]# yum install gcc gcc-c++ Installed: gcc-c++.x86_64 0:4.8.5-11.el7 Dependency Installed: libstdc++-devel.x86_64 0:4.8.5-11.el7 Complete!
再次編譯
[[email protected] qemu-2.9.0]# ./configure --enable-rbd ERROR: User requested feature rados block device configure was not able to find it. Install librbd/ceph devel
報找不到ceph 的librdb我們繼續裝包

再次編譯
