Maaz — Tue, 14 Mar 2006 13:24:04 GMT

I have some data on a FreeBSD OS partition(ufs), and I cant mount it under AS 4.
is there any patch/rpm available to mount ufs under redhat AS 4.

if your kernel support ufs filesystem (or "lsmod" shows the ufs module), then you can mount FreeBSD partitions by executing the following command:

mount -t ufs -o ufstype=44bsd /dev/hdaX /mnt/freebsdpartition

No the kernel doesnt support ufs. lsmod doesnt show the ufs module.
Is there any rpm/.gz available to support the UFS under redhat AS 4 ?

Seems you have to include both UFS filesystem support (read only) and BSD disklabel (FreeBSD partition tables) support to the kernel or install generic 2.6.9 kernel.

Maaz,
did you try to run mount command?
as far as I remember, you don't need to see ufs module in "lsmod", mount command should load it automatically.

Hi

You wont be able to write to a UFS partition.
In order to mount it readonly use the command given by Sergies.

Cheers

mount command doesnt mount the ufs filesystem, following is the message produce by mount command when i try mount the ufs filesystem:
mount: fs type ufs doesnt support by the kernel

After download u2fs-0.4.3.tar.gz from ftp://metalab.unc.edu/pub/Linux/ALPHA/ufs/
#cd /usr/src
#tar zxvf u2fs-0.4.3.tar.gz
now instead of a Directory, i found 3 files
u2fs-0.4.3.patch, u2fs-0.4.3.lsm and u2fs-0.4.3.readme.
#cat u2fs-0.4.3.readme
.
.
Apply it with the following commands,
cd /usr/src
tar xvfz u2fs-0.4.3.tar.gz
patch -p0 < u2fs-0.4.3.patch

Now prblm is that when I ran the "patch -p0 < u2fs-0.4.3.patch" i got the "File to patch:" prompt. When I press just "enter" it says Skipping File[y]: y

# patch -p0 < u2fs-0.4.3.patch
File to patch:
Skipping[y]:y

but when I provide a parameter/input to File prompt, here is the output
# patch -p0 < u2fs-0.4.3.patch
File to patch: u2fs-0.4.3.patch
patching file u2fs-0.4.3.patch

Perhaps you used the wrong -p or --strip option?

ufs read-only support is already included into 2.6 kernel. You only need to install rpm package and try to mount your share agin.

Packages for 32-bit x86:

kernel-2.6.9-34.EL.i686.rpm
or
kernel-smp-2.6.9-34.EL.i686.rpm (for SMP version)

Current kernel version is 2.6.9-5.EL-i686. Should I have to upgrade it ?
from where I can have kernel-2.6.9-34.EL.i686.rpm

#mount -t ufs -o ro -o ufstype=44bsd /dev/hdaX /mnt/freebsdpartition
