Symptoms
命令“server_df server_2”失败,并显示“Error 2: server_2 :No such file or directory failed to complete command“:
[nasadmin@ssgnas03cs0 ~]$ server_df server_2 server_2 : Error 2: server_2 : No such file or directory failed to complete command
升级前运行状况检查失败,并显示以下错误:
Blades : Check if root filesystem is too large Error HC_DM_14505148436: Output from command "/nas/bin/server_df server_2" has no information on file system root_fs_2 Blades : Check if root filesystem has enough free space Error HC_DM_14505148440: Output from command "/nas/bin/server_df server_2" has no information on file system root_fs_2 Blades : Check if file system usage is under limit Error HC_DM_14505148563: Could not determine available disk space for the mounted file systems on the following Blades: * server_2
所有其他 server_df 命令均可成功对付其他数据移动器:
[nasadmin@ssgnas03cs0 ~]$ server_df server_3 server_3 : Filesystem kbytes used avail capacity Mounted on root_fs_common 15368 5280 10088 34% /.etc_common root_fs_3 258128 6184 251944 2% /
Cause
此实例的根本原因是卸载了 server_2 的根文件系统。
[nasadmin@ssgnas03cs0 ~]$ server_mount ALL server_2 : <------ nothing mounted server_3 : root_fs_3 on / uxfs,perm,rw root_fs_common on /.etc_common uxfs,perm,ro
当您列出所有文件系统时,很明显server_2的根文件系统“root_fs_2”被列为未使用,因为它已卸载。
[nasadmin@ssgnas03cs0 ~]$ nas_fs -l id inuse type acl volume name server 1 n 1 0 10 root_fs_1 2 y 1 0 40 root_fs_common 3,2 3 n 5 0 73 root_fs_ufslog 4 n 5 0 76 root_panic_reserve 5 n 5 0 93 root_fs_d3 6 n 5 0 94 root_fs_d4 7 n 5 0 95 root_fs_d5 8 n 5 0 96 root_fs_d6 9 n 1 0 12 root_fs_2 <------------ inuse = n 10 y 1 0 14 root_fs_3 2
Resolution
在客户请求支持人员帮助之前,数据移动器已完成重新启动,未看到任何改善。要解决此问题,请以“root”用户身份登录到主控制站,并将文件系统“root_fs_2”重新装载到 Data Mover server_2:
[root@ssgnas03cs0 nasadmin]# server_mount server_2 root_fs_2 / server_2 : done
确保重新装载根文件系统:
[root@ssgnas03cs0 nasadmin]# server_mount ALL server_2 : root_fs_2 on / uxfs,perm,rw root_fs_common on /.etc_common uxfs,perm,ro server_3 : root_fs_3 on / uxfs,perm,rw root_fs_common on /.etc_common uxfs,perm,ro
装载根文件系统后,发出“server_df server_2”命令以确保成功完成:
[root@ssgnas03cs0 nasadmin]# server_df server_2 server_2 : Filesystem kbytes used avail capacity Mounted on root_fs_common 15368 5280 10088 34% /.etc_common root_fs_2 258128 6264 251864 2% /
Additional Information
在此特定实例中,客户正在清理不必要的文件系统,以回收 NAS 池的空间。在清理过程中,他们永久卸载了该文件系统,并尝试删除数据移动器server_2的根文件系统“root_fs_2”。切勿删除数据移动器的根文件系统。
