This automatically calls L<sync(2)> before the operation,
so that the maximum guest memory is freed.

+This runs C<e2fsck -p -f device>, ie. runs the ext2/ext3
+filesystem checker on C<device>, noninteractively (C<-p>),
+even if the filesystem appears to be clean (C<-f>).
+
+This command is only needed because of C<$h-E<gt>resize2fs>
+(q.v.). Normally you should use C<$h-E<gt>fsck>.

This resizes an ext2 or ext3 filesystem to match the size of
the underlying device.
+I<Note:> It is sometimes required that you run C<$h-E<gt>e2fsck_f>
+on the C<device> before calling this command. For unknown reasons
+C<resize2fs> sometimes gives an error about this and sometimes not.
+In any case, it is always safe to call C<$h-E<gt>e2fsck_f> before

Remove the single file C<path>.
