Hello everyone, I have met a ceph-fuse crash when i add osd to osd pool. I am writing data through ceph-fuse,then i add one osd to osd pool, after less than 30 s, the ceph-fuse process crash. The ceph-fuse client is 10.2.2, and the ceph osd is 0.94.3, details beblow: <pre> [root@localhost ~]# rpm -qa | grep ceph libcephfs1-10.2.2-0.el7.centos.x86_64 python-cephfs-10.2.2-0.el7.centos.x86_64
