*** Bug 950626 has been marked as a duplicate of this bug. ***
Discussion in: https://www.redhat.com/archives/dm-devel/2013-March/msg00002.html Patch in: https://patchwork.kernel.org/patch/2183891/ However, I do not think this patch works. I am waiting for an official build with the fix in it.
Proposing as a FinalBlocker: The installer must be able to complete an installation using any network-attached storage devices (e.g. iSCSI, FCoE, Fibre Channel)
We pulled in the patch to f19 and it's upstream now in the 3.10-rc1 kernels in rawhide. I've not seen any further occurrences of this.
