Symptoms
命令「server_df server_2」失敗,並顯示「錯誤 2: server_2:沒有此類檔案或目錄無法完成命令」:
[nasadmin@ssgnas03cs0 ~]$ server_df server_2 server_2 : Error 2: server_2 : No such file or directory failed to complete command
升級前執行狀況檢查失敗,並出現下列錯誤:
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 命令可針對其他資料移動器成功工作:
[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
此實例中的根本原因是server_2的根文件系統已取消掛接。
[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
當您列出所有文件系統時,很明顯server_2的根文件系統“root_fs_2”被列為未使用,因為它已卸載。
[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
在客戶向支援部門要求協助之前,資料移動者已完成重新開機,且沒有任何改善。若要解決此問題,請以「root」使用者身分登入主要控制站,然後將檔案系統「root_fs_2」重新掛接至資料移動者server_2:
[root@ssgnas03cs0 nasadmin]# server_mount server_2 root_fs_2 / server_2 : done
確定已重新掛接根檔案系統:
[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
掛接根檔案系統後,發出「server_df server_2」命令以確保其成功完成:
[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
在此特定情況下,客戶正在清理不必要的檔案系統,以回收 NAS 集區的空間。在清理過程中,他們永久取消掛接,並嘗試刪除資料移動者server_2的根檔案系統「root_fs_2」。永遠不應刪除資料移動者的根檔案系統。
