This has happened to me too. Reiserfs v3 journals metadata only. If you
expect your data to survive unexpected poweroffs you're in trouble.
It's hardly a secret. If you need full journalling, use ext3 +
data=journal. Even then, if you're using IDE disks, there's still a
chance data won't get written to disk (make sure write caching is turned
off). If you want to go further, you'll need something with battery
backed cache (like a decent SCSI RAID card). It's a question of how much
time / effort / money you're willing to put in.
Even with a totally trashed reiserfs I was able to recover most of the
data. I ended up with loads of files in lost+found, but the important
stuff survived with filenames intact.
Anyway, reiserfs v4 will support transactions and transcrashes.
Which is nice.
