Bug #64788
Updated by Kefu Chai 2 months ago
librbd uses msgr to talk to its Ceph cluster. if the client's nic is hot unplugged, there is chance that @EpollDriver::del_event()@ crashes crash because @epoll_ctl(epfd, EPOLL_CTL_DEL, fd, &……)@ returns @-ENOENT@. as its caller, @EventCenter::delete_file_event()@ considers its a signal of a bug.
