Copy the entire data directory tree to some other medium immediately, and preserve this copy. If you hit bad blocks, retry if possible. If you just can't read some portions of it, you need to get what you can, and make notes of any garbage or missed portions of files. Use the copy as a source to copy onto a reliable storage system. Without knowing more about what sort of storage system you're talking about it is hard to give advice or predict whether it might be fixable somehow. If you try to run a database on failing hardware, it will not be a pleasant experience. -Kevin -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
