Hello all, Background: DB resides on a mirrored array, HD1 goes bad and before it can be replaced, HD2 starts throwing hardware errors. We were able to get a DD from HD2 and have restored the box quite successfully with the exception of the pg db. There WAS corruption to the filesystem. Since the last backup, a significant number of records have been added to the db. If there is a way to recover some data, it would likely be easier to reconcile and fix manually than reenter. Box is FreeBSD 8, postgresql version 8.1. Progress so far: On new hardware, installed pg8.1 and restored data directory and attempted to start pg. After fixing some config differences, it complained of a missing pg_clog/xxx file. After searching the archives for hints, added a file of zero's and pg starts successfully. The db in question exists with what appears to be intact structure. When attempting to dump the db ran into the error: "could not open relation 1663/16385/16400: No such file or directory" and run into similar errors (with different relation numbers) trying to select * from certain tables. I'm stuck here. Assuming the damage to filesystem, what is the best a way forward? Does the relation error indicate damage to the data? or to an index??? Is there a process I can do to try and salvage partial data? Thanks for any help/tips/suggestions.
