昨天我的数据中心出现了电源问题，我的 nobreakers 在 30 分钟后就失效了，这是我迄今为止见过的最糟糕的情况之一。我正在运行一个 freeNas 服务器，使用 raidz1-0。开机后，我注意到一个严重警报：
卷 Raid (ZFS) 状态为“降级”：一个或多个设备出现错误，导致数据损坏。应用程序可能会受到影响。
所以我检查了磁盘状态，结果比我想象的要严重，运行“zpool 状态 -v“
我收到以下消息：
pool: Raid
state: DEGRADED
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

我的整个磁盘阵列都已降级，但闪烁的 LED 显示“正常”。现在我正在尝试清理，也许这不会起作用。我很恐慌，因为有两个 ISCSI 卷，包含 6 个 VM 服务器。我将这些 iscsi 磁盘安装在 Linux 机器上，以便从那里移动我的服务器文件，但在运行 cp 和 rsync 时出现 I/O 错误。
有人遇到过类似的事情吗？有什么办法吗？
我的服务器设置是：Dell PowerEdge R720 存储服务器 10x HD Dell 4TB 15k RPM 65GB RAM Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz
任何建议都将受到赞赏。
