首先必須先檢查是否目前的kernel版本已包含該有的模組
1. #cd /usr/src/linux-2.X
2. #make menuconfig
3. check "CONFIG_EXPERIMENTAL" under "Code maturity level options" and "CONFIG_EXT2_RESIZE" under "File systems" to see if it is build-in kernel or build as module. if the answer is yes, then your kernel is supported now. if don't or you didn't see the option in your kernel, then go though following,
4. you have to patch your kernel first,
5. go to official web to download the version which you would like to install, for example ext2resize-1.1.19 and download the tarball package onto your system.
6. # tar -jxvf ext2resize-1.1.19.tar.bz2
7. # cd /usr/local/src/ext2resize-1.1.19/patches
8. if your kernel is 2.4.8, then go to /usr/src/linux-2.4.8
9. # `patch -p1 ＜ /path/to/patch/online-ext2-2.4.8.diff'
10. repeat step one to three, then activate the option in kernel configuration,
11. Build the kernel `make dep; make bzImage; make modules'
12. Install the kernel (as appropriate for your system). and reboot, after reboot, you have the supported kernel.
*Note: all patches are under /${EXTRACT_PATH}/patches/
