我在 iscsi 和 lvm 共享逻辑卷上设置了一个 raid6 阵列，用来确保 iscsi 网络中的一个节点部分每次只能使用 raid 卷。
今天我无法停止音量。以下是我所看到的（简短）完整跟踪：
[root@ceph03 ~]# mdadm --stop /dev/md/disk12
mdadm: failed to stop array /dev/md/disk12: Success
[root@ceph03 ~]#
请忽略上面提示中的 ceph 引用；设置中没有任何与 ceph 相关的内容。
当我运行上述命令时，我看不到任何线索/var/log/messages，尽管显示了这个跟踪：dmesgdmesg

但是当我尝试停止数组时没有额外的输出。
对于上述命令和跟踪的上下文：
[root@ceph03 ~]# ls -l /dev/md*

brw-rw---- 1 root disk 9, 125 Apr 11 16:45 /dev/md125
brw-rw---- 1 root disk 9, 126 Apr 11 16:45 /dev/md126
brw-rw---- 1 root disk 9, 127 Apr 11 16:45 /dev/md127

[root@ceph03 ~]#
据我所知，该设备没有用于其他任何用途：
[root@ceph03 ~]# lsblk /dev/md124

md124 9:124 0 7.3T 0 raid6
[root@ceph03 ~]#
网络中的所有节点都运行 Rocky Linux 9.1。我还能在哪里查找阻止我停止阵列的原因？
