Barriers are not supported by some block devices. This includes at least most software raid and most dm devices. Though I have seen suggestions that dm devices with one underlying device (in particular dmcrypt) are getting support for that. I don't know what the current status of that is. When you try to use barriers when you can't they just get disabled and things should still work. The only difference will be if there is a crash of some kind, in which case some stuff may be written out of order which might be problematic. This is unlikely to be the cause of your boot problems. -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
