使用rbd-nbd unmap devpath命令进行unmap操作,其实只有两行代码:int nbd = open_device(devpath.c_str())和ioctl(nbd, NBD_DISCONNECT)(NBD_DISCONNECT是nbd的协议原语之一)。 使用rbd-nbd list-mapped命令查看所有map的nbd设备和rbd镜像的对应关系,其步骤是:从x=0开始遍历,通过/sys/block/nbd<x>/pid获取该n...

rbd-nbd creates a log file per volume under the cephLogDir path on NodeStage(map) and removed the same on the respective NodeUnstage(unmap).There are different strategies to maintain the logs remove: delete log file on unmap/detach (default behaviour) compress: compress the log file to gz...
