The gist is that F21 installer has issued e2fsck -f -p on *all* ext volumes by the time the Welcome+Language has displayed. Thus there's no opt out. The Fedora 20 installer doesn't do this, it only does resize2fs -P and dump2fs to collect information on all ext volumes, which is fast. e2fsck -f -p isn't guaranteed to exit quickly at all because preen is forced even if the fs is marked clean, and this is issued to all ext volumes (I think in sequence rather than in parallel). At a certain point any busy e2fsck will hang anaconda. The original reporter experienced such a hard freeze due to an external with an ext3 volume for which e2fsck wasn't exiting quickly. The work around was to disconnect that external drive and re-run the installer. It's too late to fix for Fedora 21, but it might be worth a Common Bugs. https://bugzilla.redhat.com/show_bug.cgi?id=1170803 -- Chris Murphy -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
