I get message when #grub-mkconfig -o /boot/grub/grub.cfg

Code:

File descriptor 40(/null) leaked on vgs invocation. Parent PID 15025 /usr/sbin/grub-probe

what does that mean?

log_null

Is a LVM tools warning, when calling vgs binary ( which tried an unexpected file descriptor ) Probably your grub.cnf was created without errors despite of these warnings, right?

You can suppress these warning as mentioned in man(8) lvm :

Quote:

On invocation, lvm requires that only the standard file descriptors stdin, stdout and stderr are available. If others are found, they get closed and messages are issued warning about the leak. This warning can be suppressed by setting the environment variable LVM_SUPPRESS_FD_WARNINGS.
