Hi, I found many error info in the ganesha.log when stop nfs-ganesha.service, as follows. ganesha.log: ：ganesha.nfsd-1550083[Admin] mdcache_lru_clean INODE:F_DBG:Trusting op_ctx export id 2 ：ganesha.nfsd-1550083[Admin] posix2fsal_error:FSAL:CRIT:Default case mapping Transport endpoint is not connected (107) to ERR_FSAL_SERVERFAULT ：ganesha.nfsd-1550083[Admin] mdcache_Iru_clean:INODE LRU:CRIT:Error closing file in cleanup:Undefined server error My version info: Ganesha-3.3+FSAL_CEPH(ceph version 14.2.10)； I went through the relevant code and still didn't understand the intention of the code. static void release_export(struct gsh_export *export) { export->fsal_export->exp_ops.prepare_unexport(export->fsal_export)； //mdcache_prepare_unexport /* Release state belonging to this export */ state_release_export(export); /* Flush FSAL-specific state */ export->fsal_export->exp_ops.unexport(export->fsal_export,obj); //mdcache_unexport } The first thing to declare is that USE_FSAL_CEPH_ABORT_CONN has been opened, so calling ceph_abort_conn() in ceph_prepare_unexport will abort the connection and umount. However, the following operation will still need export->cmount and the connect, such as fsal_close() in mdcache_Iru _clean(). I think that is the reason for the error printing. To sum up, I have two questions: 1、Isn't it reasonable to disconnect in prepare_unexport before mdcache_lru_clean? 2、What is the intention of doing so? What will happen if I turn off USE_FSAL_CEPH_ABORT_CONN? | | liuwei_coder | | 邮箱：liuwei_coder@163.com | 签名由 网易邮箱大师 定制
