[NAS] DSM 6.2.3 掉盘如何救

[小天管理]

机器蜜獾超存 6 盘识别。 系统 DS918+ DSM6.2.3-25426 存储池 6 块 500G ，组 RAID6 某天系统报堪用，一个硬盘因为反复断联掉了。随机关机换了一块新盘。然后开机，显示存储空间损毁。共享文件夹找不到文件，存储池显示降级堪用。 按理说存储池降级应该不会影响存储空间的。

查找相关资料，通过 ssh 登录查看池状态。

root@CGQ:~# cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md2 : active raid6 sdc3[6] sdh3[5] sdg3[8] sdf3[3] sde3[7] 1934258176 blocks super 1.2 level 6, 64k chunk, algorithm 2 [6/5] [U_UUUU]

md1 : active raid1 sdh2[4] sdg2[3] sdf2[2] sde2[1] sdc2[0] 2097088 blocks [16/5] [UUUUU___________]

md0 : active raid1 sdc1[1] sde1[4] sdf1[0] sdg1[2] sdh1[3] 2490176 blocks [16/5] [UUUUU___________]

unused devices: <none>

看起来没问题，就想重新挂载下试试。

root@CGQ:~# synospace --stop-all-spaces root@CGQ:~# mdadm --assemble --scan mdadm: No arrays found in config file or automatically

池无法挂载。奇怪的现象。再次查看池状态。

root@CGQ:~# cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md2 : active raid6 sdc3[6] sdh3[5] sdg3[8] sdf3[3] sde3[7] 1934258176 blocks super 1.2 level 6, 64k chunk, algorithm 2 [6/5] [U_UUUU]

下一步如何做，各位高手给个意见
