Help needed with r4 meta-data analyze and fix [sdb]

Hello Edward,

- What commands can be done to analyze and fix the r4 file
system/meta-data ?
- What commands do you run against unpacked meta-data ?

Some questions:

1. How can r4 volume be mounted-accessed ?
2. Is their a patch available for reiser4progs  'Wrong order of keys'
using [reiser4progs-1.0.5-43.1.x86_64] ?

Thank you for any help the commands to run.
I cannot shrink r4 volume -dont see any tools to do that.
I know files and data are on disk but just trying to access it.

Thankyou Glenn
