Hi list,
This is what I've done so far ( I apologize for the large amount of
lines/info!):

Then, not thinking at all, I went back and ran fdisk, since I forgot
to run fdisk, it was 2:00 a.m. in the morning!!!
root at ptb3 rc3.d]# fdisk /dev/sdb
The number of cylinders for this disk is set to 53757.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

The partition table has been altered!

partitions, please see the fdisk manual page for additional
information.
Syncing disks.
So, now I have these errors when running most of the LVM cmds!!

Hence, chaos ensues on this machine....
Please let me know if "vgcfgrestore" will work for me.
Or do I try to remove the partition from fdisk? I really don't think
that will help though!
I think the damage is done from the partition write to the EXP300 disk
array.
Also, if I reboot, will there be a disaster!(For fdisk...)
This is a production machine.
Please help me if you can...
TIA!
