You want the block devices to be in a subdir? Yes, the normal arrangement is for the "etherd" subdirectory in /dev to contain the character and block devices for the aoe driver. It looks like, ecashin@ellijay:~$ ls -l /dev/etherd total 0 c-w--w---- 1 root disk 152, 3 Dec 7 16:24 discover brw-rw---- 1 root disk 152, 16 Dec 7 17:02 e7.0 brw-rw---- 1 root disk 152, 0 Dec 7 17:02 e7.1 cr--r----- 1 root disk 152, 2 Dec 7 16:24 err c-w--w---- 1 root disk 152, 6 Dec 7 16:24 flush c-w--w---- 1 root disk 152, 4 Dec 7 16:24 interfaces c-w--w---- 1 root disk 152, 5 Dec 7 16:24 revalidate ecashin@ellijay:~$ (The block device minor numbers are different for this aoe6-55 driver than they would be for earlier versions. This aoe6-55 driver relies on udev and assigns minor numbers dynamically. Older drivers can't do that, and so have a more limited range of possible AoE shelf and slot addresses.) -- Support - http://www.coraid.com/support/howto.html Ed L Cashin ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
