在一台F4800上查看metastat -t的输出如下：\r\nd1: Mirror\r\n Submirror 0: d11\r\n State: Needs maintenance Tue Jan 15 19:31:24 2008\r\n Submirror 1: d21\r\n State: Needs maintenance Tue Jan 15 23:20:51 2008\r\n Pass: 1\r\n Read option: roundrobin (default)\r\n Write option: parallel (default)\r\n Size: 71455872 blocks (34 GB)\r\n\r\nd11: Submirror of d1\r\n State: Needs maintenance Tue Jan 15 19:31:24 2008\r\n Invoke: metasync d1\r\n Size: 71455872 blocks (34 GB)\r\n Stripe 0:\r\n Device Start Dbase State Reloc Hot Spare Time\r\n c0t0d0s1 0 No Okay Yes Tue Jan 15 19:30:45 2008\r\n\r\n\r\nd21: Submirror of d1\r\n State: Needs maintenance Tue Jan 15 23:20:51 2008\r\n Invoke: metasync d1\r\n Size: 71455872 blocks (34 GB)\r\n Stripe 0:\r\n Device Start Dbase State Reloc Hot Spare Time\r\n c0t1d0s1 0 No Okay Yes Tue Jan 15 19:31:05 2008\r\n\r\n\r\nd0: Mirror\r\n Submirror 0: d10\r\n State: Needs maintenance Tue Jan 15 19:31:16 2008\r\n Submirror 1: d20\r\n State: Needs maintenance Tue Jan 15 23:20:57 2008\r\n Pass: 1\r\n Read option: roundrobin (default)\r\n Write option: parallel (default)\r\n Size: 71689920 blocks (34 GB)\r\n\r\nd10: Submirror of d0\r\n State: Needs maintenance Tue Jan 15 19:31:16 2008\r\n Invoke: metasync d0\r\n Size: 71689920 blocks (34 GB)\r\n Stripe 0:\r\n Device Start Dbase State Reloc Hot Spare Time\r\n c0t0d0s0 0 No Okay Yes Tue Jan 15 19:30:32 2008\r\n\r\n\r\nd20: Submirror of d0\r\n State: Needs maintenance Tue Jan 15 23:20:57 2008\r\n Invoke: metasync d0\r\n Size: 71689920 blocks (34 GB)\r\n Stripe 0:\r\n Device Start Dbase State Reloc Hot Spare Time\r\n c0t1d0s0 0 No Okay Yes Tue Jan 15 19:30:55 2008\r\n\r\n\r\nDevice Relocation Information:\r\nDevice Reloc Device ID\r\nc0t1d0 Yes id1,sd@THITACHI_DK32EJ-72NC_____415D2328\r\nc0t0d0 Yes id1,sd@THITACHI_DK32EJ-72NC_____415C4966\r\n\r\nd0 d1的子镜状态都是Needs maintenance，为何它们的设备状态是Okay的？子镜需要维护这是什么原因做成的，如果按照它提示的执行metasync d0,metasync d1有没有风险？
