linux – 如何强制mdadm使用udev设备名称而不是/ dev / sdX

问题主要在于标题.

mdadm和/ proc / mdstat坚持用他们的“传统”/ dev / sdX名称列出md成员.
我想要的是让他们使用更新的udev设备名称(例如/ dev / disk / by-path和by-id).

我已经改变了/etc/mdadm/mdadm.conf

DEVICE partitions

至

DEVICE /dev/disk/by-path/*

但这似乎根本没有效果.

此外,使用旁路设备名称来终止阵列.

这是在Ubuntu 11.10上.

当前/ proc / mdstat：

~# cat /proc/mdstat 
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] 
md1 : active raid5 sdi[4] sde[2] sdh[1] sdd[0]

解决方法

不可能.这些符号链接(由udev创建)对于用户空间很方便,并且mdadm可以在它与内核通信时使用它们…这将查看该块以查找真实设备.没有用于通知内核别名或新名称的机制,而是使用其内部规范名称生成这些消息的内核.

有几次尝试将/sys/block/<disk>/alias_name引入Linux内核并更新输出以使用别名,但最近的尝试是rejected.
