Description of problem: http://www.systutorials.com/124416/shrinking-a-ext4-file-system-on-lvm-in-linux/ # lvresize --resizefs --size SIZE /dev/vg/vg_data this do a core dump line 141 (IIRC) in line: dry() { resize2fs /dev/mapper/vg_cloud-LogVol00 75G also coredump I boot with on pen disk with Fedora 21 , and I could shrinking ext4 without problem , but the root of the problem seems shrinking with e2fsprogs-1.43.1-2.fc25 Version-Release number of selected component (if applicable): Fedora 25 Alpha updated This is not a thing that I can test much , because I have to umount my /home partition, I decide resize my logical volumes , I wanted have more 10 Gigas in root fs so I shrink it from /home . Anyway the disk in an old 80gigas matrox , feel free to ask more data.
Ok, we will need more info - the core file, at least. An e2image -Q of /dev/mapper/vg_cloud-LogVol00 should also help us reproduce the problem.

Ok, I can't proceed without any further information. If you can provide it, please re-open.
