It this a continuation of the problem in you previous thread?
https://www.unix.com/unix-dummies-que...-then-yes.html

1) Please post what Operating System and version you have.
2) Can you post the commands you typed to reduce the Filesystem or Logical Volume (or both? It's not at all clear what happened)?
3) Please make it clear whether this is a system partition or a data partition?
4) Do you have a good backup of the contents of the Filesystem concerned?

From you other thread:
Quote:
still with fsck , first i have to say no , then i have to say yes, millions of time ,
once i reduce filesystem without unmounted it
that cause error on that logical volume
This does suggest that the filesystem had file extents above the new tidemark. The filesystem is probably toast, but let's see the answers to the above questions first.

Foootnote. vgcfgrestore is probably irrelevent.
