ext4 filesystem on lvm on raid causes boot to enter emergency shell

[Rick Thomas <rbthomas@pobox.com>]

When /etc/fstab has an ext4 filesystem on a logical volume which is itself
on a software raid, the system times out waiting for (I think!) fsck on that filesystem.
This causes the boot to drop into the emergency shell.

If I just type “^D" and allow the boot to continue, the filesystem is mounted but never fsck-ed.

Does anybody have a work-around for this bug so that the filesystem gets properly fsck-ed and I don’t have to go to the console to type ‘^D’ every time I need to boot the system?

Thanks!
Rick
