From 08b60623510aebddd9ac4bf61dbe2d39313dddfd Mon Sep 17 00:00:00 2001 From: Ed Cashin Date: Thu, 4 Oct 2012 17:16:47 -0700 Subject: aoe: make dynamic block minor numbers the default Because udev use is so widespread, making the old static mapping the default is too conservative, given the severe limitations it places on usable AoE addresses. Storage virtualization and larger shelves have made the old limitations too confining. These changes make the dynamic block device minor numbers the default, removing the limitations on usable AoE addresses. The static arrangement is still available with aoe_dyndevs=0, and the aoe-stat tool from the userland aoetools package, the user space counterpart to the aoe driver, recognizes the case where there is a mismatch between the minor number in sysfs and the minor number in a special device file.
