Hello,
After loosing all the data on my production server by issuing wrong lvm
commands in restoring the logical volume, I have worked for weeks to
setup my server again from scratch up. Now, today I noticed another
problem, but scared to death to touch it.
This time I have to ask you before issuing any commands as obviously I
haven't learned LVM internals.
Please find the details below. I would appreciate any help.
Thanks,
Mufit
Problem:
The system works but fdisk -l gives the following error:
