Ubuntu 12.04服务器软件RAID1 – 故障备用 – 智能输出通过 – 困惑

我想我的arrays上的硬盘驱动器有问题，我只是想解决发生了什么事情。

它说故障备用，然后重新启动它只是说删除：

/dev/md0: Version : 1.2 Creation Time : Wed Aug 15 15:28:06 2012 Raid Level : raid1 Array Size : 2920368960 (2785.08 GiB 2990.46 GB) Used Dev Size : 2920368960 (2785.08 GiB 2990.46 GB) Raid Devices : 2 Total Devices : 1 Persistence : Superblock is persistent Update Time : Wed Aug 22 16:04:16 2012 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 Name : M2FileServer:0 (local to host M2FileServer) UUID : 778e5d32:1cd810e8:dfebb663:868d66e6 Events : 45564 Number Major Minor RaidDevice State 0 8 2 0 active sync /dev/sda2 1 0 0 1 removed 

这里是分开的东西，所以你可以看到我的分区

 Model: ATA ST3000DM001-9YN1 (scsi) Disk /dev/sda: 3001GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 10.0GB 10.0GB ext4 boot 2 10.0GB 3001GB 2991GB ext4 raid Model: ATA ST3000DM001-9YN1 (scsi) Disk /dev/sdb: 3001GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 10.0GB 10.0GB linux-swap(v1) 2 10.0GB 3001GB 2991GB ext4 Model: Linux Software RAID Array (md) Disk /dev/md0: 2990GB Sector size (logical/physical): 512B/4096B Partition Table: loop Number Start End Size File system Flags 1 0.00B 2990GB 2990GB ext4 

我运行了smartctl -a / dev / sdb2，它说我通过了，但是与我的工作驱动器相比，RAW_VALUE数字非常高。

结果如下：
