Hello,
- Is there any way to access to the following r4 partition on disk ?
[dev/sdb]
- Are there any switches to help identify the problem ?
I want to copy the files to another partition.

The command fails for some reason:
How can I get the following to work ?

# mount /dev/sdb  /media/disk
mount: mount(2) failed: No such file or directory

--Thankyou Glenn

# rpm -qa | grep -i reiser4progs

    FS is consistent.



This is a bug in fsck: it jumps to wrong branch for some reasons.
Not yet fixed.

This error message literally means that mount(2) system call fails to
find a directory entry. Since you have just two of it on you command
line, it shouldn't take long to guess what.

Are you sure /media/disk mountpoint exists? If it does, what shows up
from /proc/partitions? Is sdb a removable disk? Do you have udev
running?.. 

By the way, did you try to run fsck on this disk ever since 08/26 last
year?

This looks like a generic format error. Roughly speaking, here your
current fsck fails to recognize a partition as the reiser4 one in its
current sense. The same thing may happen at runtime, so that
reiser4_mount() eventually return -ENOENT to the kernel. You should use
debugger or at least enable debugging output in the filesystem code to
be pretty confident of it.

So, my guess is that something get screwed up when you manually apply
all experimental patches against reiser4/progs release(s).

There are 2 ways to get it fixed.

The first one is to continue on with debugging, make dumps, use kgdb or
whatever kernel debugger you've got handy, etc. This routine would make
sense if you keep track of changes you do against reiser4/progs
releases, so that you will be able to identify the incompatible one and
roll it back. Either, you can guess what you are missing. It would also
help you to understand what you are doing.

Instead, you can just make use of the same mkfs/fsck, library and
kernel/module binaries that you have been using to format the disk and
mount it for the first time. Sure, if you did back it up.

In the hope it helps.
