shell lvm

Questi sono descrittori di file lasciati aperti sul dispositivo (che stavi ridimensionando).

LVM (8) dice:

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.

A chiunque stia cercando come sopprimere questi messaggi This warning can be suppressed by setting the environment variable LVM_SUPPRESS_FD_WARNINGS

— MUY Belgio,

come diceva edoput:export LVM_SUPPRESS_FD_WARNINGS=1
