Re: [linux-lvm] Desater Recovery <urgent>

All,

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..."

Regards,
Heinz    -- The LVM Guy --

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