The maint branch indeed fixed the problem. Output attached. Thanks for your effort.
(There is still a "warning" about "extent tree (at level 1) could be narrower. Fix<y>? yes" when running e2fsck after resize. When selecting yes and running the e2fsck once more the warning is still present.) root@vedlikehold:~# lvresize --resizefs -l 11776 /dev/skole-vg/root fsck from util-linux 2.31.1 /dev/mapper/skole--vg-root: clean, 139206/8331264 files, 3274416/33294336 blocks resize2fs 1.44.4 (18-Aug-2018) Resizing the filesystem on /dev/mapper/skole--vg-root to 12058624 (4k) blocks.
