Dear people, My armel KuroBox Pro (which is a marvell orion5x) has a filesystem that is potentially very fragmented and I have always used the command e4defrag to defragment it.
Unfortunately, today I tried running it as I had usually done for many years (as "e4defrag -v ." in a directory of interest), but all that I got were segfaults, something which I had never seen before (e4defrag has always been very robust). Before I file a bug report (not really sure against what package), is anybody able to confirm the problem with an armel box? (As an aside, I don't get these errors when I run e4defrag on my amd64 notebook, but, of course, the notebook doesn't have the HDD that I would like to defragment.) I installed the debug symbols package for e2fsprogs and I tried running e4defrag under gdb and this is what I got: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - root@lattes:~# gdb /usr/sbin/e4defrag GNU gdb (Debian 8.2-1) 8.2 Copyright (C) 2018 Free Software Foundation, Inc.
