Check the ownership and permissions on the /sbin/lvm_wrapper and /usr/sbin/lvm_wrapper files.

They should be:

# ll /sbin/lvm_wrapper /usr/sbin/lvm_wrapper
-r-sr-xr-x   1 root       sys        1089536 Dec  9  2012 /sbin/lvm_wrapper
-r-sr-xr-x   1 root       sys         192512 Dec  9  2012 /usr/sbin/lvm_wrapper

If the owner is incorrect, and since it is an suid executable, it will run as a user other than root which won't work.

Hello Patrick

Thank you, it was helpfull, it works fine now, exactly

/sbin/lvm_wrapper was missing and /usr/sbin/lvm_wrapper had bad owner.

So I did a copy and change owners
