Hi, I'm doing FC1 to FC4 upgrade these days and I find that the ext3 file system features of FC1 and FC4 are different. For FC4, there are three more ext3 file system features are on: they are ext_attr, resieze_inode, and dir_index. FC4: Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_file FC1: Filesystem features: has_journal filetype needs_recovery sparse_super large_file So How do I add these 3 ext3 features to untouched data partitions like /home after my server is upgraded to FC4? Do I have to do it manually? or the upgrade will do it for me automatically? I'm afraid of losing precious data but still like to have cool new features. Any suggestions are greatly welcomed. Thanks. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
