SU+J Lost files after a power failure

[David Demelier]

Hello there,

I'm writing because after a power failure I was unable to log in on my
FreeBSD 9.2-RELEASE. The SU+J journal were executed correctly but some
files disappeared, including /etc/pwd.db. Thus I was unable to log in.

I've been able to regenerate the password database with a live cd but
I'm afraid that more files had disappeared somewhere else...

I think this is a serious issue, the journal should not truncate files,
so something should have gone wrong somewhere..

Any ideas? Should I open a PR?

Regards,
