我的RAID1降级了,我需要替换/ dev / sdb.但是,我可以将/ dev / sdb5(在/ dev / md1中)标记为失败并将其删除,但我不能对/ dev / sdb1(安装在/上的/ dev / md0)执行相同的操作：
- root@kes:~# mdadm /dev/md0 --fail /dev/sdb1
- mdadm: set /dev/sdb1 faulty in /dev/md0
- root@kes:~# mdadm --detail /dev/md0
- /dev/md0:

- 0 8 1 0 active sync /dev/sda1
- 2 8 17 1 faulty spare rebuilding /dev/sdb1
- root@kes:~# mdadm /dev/md0 --remove /dev/sdb1
- mdadm: hot remove Failed for /dev/sdb1: Device or resource busy
那么我做错了什么？
解决方法
尝试：
- echo "idle" > /sys/block/md0/md/sync_action
- mdadm /dev/md0 --remove /dev/sdb1
为我工作.
