I've been tearing my hair out all day on this and not getting anywhere yet, so punting to the list ;) I have a user running mke2fs -t ext4 in a virt guest, and a mount immediately after that fails. It fails because the journal inode has an invalide i_extra_isize. I've narrowed it down to the commit (961306d3) which creates the journal with extent format; if that's commented out, it works fine. I can't for the life of me see where the problem is coming from, though. I thought we'd need a write_inode_new (emphasis on new here) for the journal inode, but switching to that doesn't help. I can't reproduce this myself... any ideas or suggestions of where to look? :) -Eric -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
