After two disks on our raid-5 system failed causing a filesystem
failure.
We could get one online again and the filesystem is at present usable
but I cannot start postgresql at the moment:
$ /usr/lib/postgresql/8.3/bin/postgres --single -D /etc/postgresql/8.3/main/
2010-05-27 09:22:48 SAST FATAL: could not stat directory "base/16400": Structure needs cleaning

in 'base' I see

I can just move the data-directory, do an initdb and use an older dump
to repair the database as it was some time ago. Fortunately the data is
not mission critical. But what if it was.
How do I recover from a situation like this?

Johann
