[CentOS-devel] Centos4/Centos3 filesystem difference?

[Les Mikesell]

I restored a tar backup of a Centos3 x86_64 box using a Centos4 x86
machine to format the disk and untar the files.  Then I used the
install cd to install grub on the actual machine but when it
booted it said the filesystem had errors and fsck refused to fix
them because the filesystem had newer features.  Is there a way to
make a backwards-compatible filesystem in the newer version and is
the difference documented somewhere?
