RedHat 7.3 compatible format

Hi,

I tried formatting a new HD for our existing RedHat 7.3 OS and it complains 
that the ext3 has incompatible ext3 flags, any ideas how to format using 'old 
ext3'?

(I am forced to format this disk inside a Debian OS)

Shana Tova,

If I'm not mistaken, you have 2 choices:

1. Format the hard drive to EXT2.
2. Upgrade to the latest 2.6.x kernel (maybe 2.4.x  kernel has the
same support for ext3, donno), and build e2fsprogs package
(http://e2fsprogs.sourceforge.net/). After that, format the disk to
ext3.

Hope this helps,
Hetz

This is from a RedHat 7.2 system that has been upgraded over the years. The
only thing original is the file that says which version it is. 

Note that if you do have to boot from a CD-ROM to rescue the system, it
will have to be RedHat 9 in order to access the ext3 file systems.

Geoff.

It might be the inode size - the man page on my Debian says the default is 256 bytes, and that 2.4 kernels won't
mount a filesystem with inodes larger than 128.
try adding -I 128 to the mke2fs flags.
