LVM Recovery Problem

[Eric Feldhusen]

I have a RHEL4(thus similar to FC3, which is why I ask here) server 
setup running with the root partition on a LVM. It was running fine 
until a 200GB dd disk image file was written to 157GB of free space. The 
dd file was from a 20GB hard drive, so I believe the problem was in the 
block size, but either way, the file system showed no increase in used 
space.  The server was restarted, and during start up as the LVMs are 
started up, the message "file descriptor 3 open, mounting read-only" 
comes up.  The system will start, badly broken, as the entire LVM is 
read-only.  I restarted the system on a RHEL4 cd1, went into rescue 
mode, removed the dd file, restarted again on the hard drives, still get 
the same error.   If I start up the system in rescue mode on the RHEL4 
cd, I can access the filesystem with no problems, I can chroot into it, 
and actually run services with no problem and the services can access 
and use the LVM with no problem.

Any suggestions on what to do?  The LVM how-to doesn't have an area that 
  fits with this problem, and I have to believe if the rescue cd will 
access the LVM without problems, it can be repaired.
