Edit kernel to support UFS read/write
 

Hey Guys,

I would like to enable read/write support for the UFS file system.

Basically, I need to be able to edit files on a Solaris HD in Kubuntu.

I have 1 HD with Kubunu installed on it, and the other is a Solaris HD. (which needs to be mounted as read/write).


This is what I have done:

Installed Kubuntu 7.04.

/usr/src/linux_dir/

attempted a "make allyesconfig" , and then "make bzImage" <- this step fails.


This is what I need help with:

1: after installation of kubuntu, what steps need to be done in order for me to mount the Solaris HD as read/write?

Can anyone help me with a step by step guide to this? This would be appreciated.

You probably already have the UFS module in the default kernel (it's been in the kernel since version 2.0). To verify, in a terminal, run 'modinfo ufs'. If you have it, modinfo will tell you so.

Beyond that, try 'menuconfig' or 'make menuconfig' to start the kernel configuration. Make bzImage will be near the last step in the configuration process.

I can only find references to read-only support for UFS. There may be third-party patches to give write support, buy I wouldn't bet on it.

Assuming you actually need to compile a new kernel:

make menuconfig

make

make modules

make modules_install

make install

If you never compiled a kernel or ever configured one well do it on a system with more than one kernel and kernel tree ok if I screw up one kernel I have three to fall back on to run the system. this is not for newbies cd /usr/src/uname-r kernel type make xconfig then load your old config file then scrole to the section you need check yes. then you will need to build the modules make install then a make modules_install.good luck

When running make menuconfig, i get this:

/usr/src/linux-headers-2.6.20-15-generic# make menuconfig

You need the ncurses header files installed.

err how do i do that?

You skipped the first step: "make oldconfig".

if you make oldconfig then you have the same old settings. but after playing with make xconfig I see it loads defaults. so I said in make xconfig load your .config file then scroll to the place and mark yes . to make oldconfig would not help him because the same old setting.


cd linux
make mrproper

make config
1 make
2 make install
3 make modules_install

so when I use the xconfig i have the option to load a old config
then edit then save.
then do steps 1,2,3,

If you want to run make menuconfig you will need the ncurses headers (similarly, for make xconfig and make gconfig you will need the Qt and GTK headers respectively). Since you are running Kubuntu, these packages should be available in Synaptic (e.g., libncurses5-dev or similar).

If you prefer not to install any system headers, you can instead use make config which is a simple, line-by-line dialog.
