公司的HP-Z210拿來做server,裝CentOS,兩顆硬碟做RAID1 前幾天安裝完系統開機訊息是這樣的: RAID Volumes: ID Name Level Strip Size Status Bootabl 0 Volume0 RAID1(Mirror) N/A 233.8GB Initialize Yes Physical Devices: Port Device Model Serial # Size Type/Status(Vol ID) 0 Maxtor 6V250F0 V592283G 233.7GB Member Disk(0) 1 Maxtor 6V250F0 V503KSXG 233.7GB Member Disk(0) 現在是這樣的: RAID Volumes: ID Name Level Strip Size Status Bootabl 0 Volume0 RAID1(Mirror) N/A 233.8GB Degraded Yes Physical Devices: Port Device Model Serial # Size Type/Status(Vol ID) 0 Maxtor 6V250F0 V592283G 233.7GB Member Disk(0) 1 Maxtor 6V250F0 V503KSXG 233.7GB Spare Disk 這樣的訊息是代表什麼??? 再來 mdadm --detail /dev/md127 觀察是這樣的: /dev/md127: Container : /dev/md0, member 0 Raid Level : raid1 Array Size : 245114880 (233.76 GiB 251.00 GB) Used Dev Size : 245115012 (233.76 Gib 251.00 GB) Raid Devices : 2 Total Devices : 1 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 UUID : c5e4e272:73329def:8dc9fd9d:b8991b6e Number Major Minor RaidDevice State 0 8 0 0 active sync /dev/sd1 1 0 0 1 removed 接著 cat /proc/mdstat 觀察是這樣的: Personalities : [raid1] md126 : inactive sdb[0](S) 1105 blocks super external:imsm md127 : active raid1 sda[0] 245114880 blocks super external:/md0/0 [2/1] [U_] md0 : inactive sda[0](S) 2364 blocks super external:imsm unused devices: <none> 照上面的訊息顯示,我現在的raid 1究竟是有沒有正常運作(兩硬碟同步)? 麻煩各位了! thx~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.255.5.151
