Talk:HOWTO aoe

From Gentoo Linux Wiki

This seems badly named. If nobody objects, it should probably be moved to HOWTO ATA over Ethernet PStatic 00:42, 20 April 2006 (UTC)

Isn't it possible to have multiple clients access the same server "disk", as long as the filesystem on the disk is some form of clustering file system (like GFS)? - Paul Rogerson 17:33, 26 July 2006 2006 (CDT)

aoetools also needs an update to properly discover aoe discs at boot time and to properly handle discover and mounting of raid devices. the insertion of the aoe module happens before the network is up and therefor doesn't discover aoe disks. So the user has to manually run aoe-discover. already available by deactivating automatic loading of modules and then specifying the order of the modules to load in modules.autoload.d and then using udev to generate the device-files, or just include the network devices and AoE in the kernel since that will also trigger a rescan.

So further, since there are no /dev/etherd/e*.* devices present during boot then the kernel md raid stuff doesn't know that they exist and doesn't assemble and mount any raid devices that rely on aoe discs. basically aoetools needs an /etc/init.d/aoe script to force discovery during boot and the md startup system needs to be aoe aware. Check the link to the initramfs script on the bottom of this page

Initramfs image for booting from AoE devices now available from http://bladerunner.mine.nu, premade for x86_64 and with a short description on how to modify it for other platforms.
