aoe磁盘在/ proc / partitions中为/ dev / sda

Question

Im using AoE disk for a particular Linux installation.

I need to tell to linux system to see /dev/etherd/e0.0 as a /dev/sda, im already create a hard link of /dev/etherd/e0.0 to /dev/sda an it works.

But now i need to make system see the /dev/sda (/dev/etherd/e0.0) in /proc/partitions.

There exists a command to do that ?

thank you.

There is no way to do that. The /dev/sda node is reserved for devices which are accessible using the SCSI/SATA/IDE disk driver; AoE devices do not use that mechanism, so they will always show up differently. Creating a hard link will just confuse matters; doing so is inadvisable.

I'm not 100% certain whether it's even possible to boot a machine over AoE. It might be possible to do directly if all the configuration is automatic, or can be performed by setting kernel command line parameters; chances are that you will need to create a custom initrd to initialize the network and bring up the volume.
