出现背景
ceph出现意外断电，或者还原失败什么的场景，可能会出现这样的报错。
出现原因
ceph中的某个rbd损坏
解决方案
使用命令rbd ls -l {poolname}这里吧poolname换成自己的池。
oot@node1:~# rbd ls -l nvme_pool
rbd: error opening vm-101-disk-1: (2) No such file or directory
rbd: error opening vm-116-disk-0: (2) No such file or directory
rbd: error opening vm-116-disk-1: (2) No such file or directory

base-996-disk-1 250 GiB 2
base-996-disk-1@__base__ 250 GiB 2 yes不出意外，会出现error，然后把出现error的rbd删了就行。
使用命令 rbd -p {poolname} rm {rbdname}
