This is both to prevent ext3 from accidentally being claimed as ext4, as well as to put a psychological barrier in place. ;) When creating the filesystem, you must do: [root]# mkfs.ext3 -E test_fs /dev/<device> for pre-existing filesystems, to set the flag, do: [root]# debugfs -w /dev/sda5 debugfs 1.40.5 (27-Jan-2008) debugfs: set_super_value s_flags 4 debugfs: quit If you don't do this, you may get a message like this upon bootup: <div class="Ih2E3d"> EXT4-fs: dm-1: not marked OK to use with test code </div>... and welcome to "alpha" :) Please copy back to fedora-test if you like, I'm not on that list... -Eric <div class="Ih2E3d"> > mount: error mounting /dev/root on /sysroot as ext4dev: Invalid arguement > setuproot: moving /dev failed: No such file or directory > setuproot: error mounting /proc: Nos such file or dierctory > setuproot: error mounting /sys: No such file or directory > Mount failed for selinuxfs on /selinux: No such file or directory > (enforcing=0) <- booted up with (selinux=0) same thing > switchroot: mount failed: No such file or directory > Booting has failed. > > Default alpha kernel 2.6.24-2.fc9 I get: > > Starting udev: udevd-event[1270]: node_symlink: device node '/dev/rtc' > already exists, link > to '/dev/rtc0' will not overwrite it > > > Just sits there. > > I was going to try 'rescue mode' from the install dvd and mount my > system, but apparently that isn't setup for ext4 either.. :( > > I think I'm looking at a dead duck, but if anyone has a suggestion, let > me have it. > </div>> Not sure if *Eric Sandeen is on this list or not.* > > > </blockquote></div> At this point it sounds like I need to do a re-install and do this: [root]# debugfs -w /dev/sda5 debugfs 1.40.5 (27-Jan-2008) debugfs: set_super_value s_flags 4 debugfs: quit Before I do the updates and boot.
