I supported Ralf on the phone and we analyzed, that the ext2 filesystem was
already *very* messy before e2fsadm could be run.
Brief history was:
- fs run as ext3 (heavily) used for weeks
- try to shrink unmounted fs with e2fsadm (using resize2fs) made e2fsadm
end early because manual fsck was required; this was the point in time
where a readonly mount and a backup was needed (but didn't happen) in
order to save as much data as possible
- manual "fsck -fy" was run exposing piles of messages :-( which
convinces me, that the fs data was messy already afterwards
- e2fsadm was run "successfully" ending up with smaller fs and larger
LV size which is most likely caused by a resize2fs exit code != 0.
As already mentioned in other mails of this thread: no backups :-(
"Remind people of taking backup, remind people of taking backup, remind..."

*** Software bugs are stupid.
Nevertheless it needs not so stupid people to solve them ***
