http://www.uow.edu.au/~andrewm/linux/ext3/ There you'll find the patch for 2.4.10 and the documentation. Basically, grab the patch, cd to your sources, gunzip path/to/patch | patch -p1, then do a make config (or menuconfig or whatever). I have upgraded machines using ext2 to ext3 while they were running. There is one important thing to note. In 2.4.10, running tune2fs -j /dev/hdXX then rebooting won't give you an ext3 partition. You must run tune2fs in a different kernel (like your existing one), because of some changes in the 2.4.10 kernel. If you need to delete the .journal file, because you forgot to create the journal in 2.4.9 (or whatever kernel) use: "chattr -i .journal; rm .journal" BEFORE running "tune2fs -j" (from https://listman.redhat.com/pipermail/ext3-users/2001-September/001467.html) Oh, and make sure e2fsprogs and mount are the correct versions. Discussions about ext3 on 2.4.10 are in September's archives: https://listman.redhat.com/pipermail/ext3-users/2001-September/thread.html Andrew.
