I thought this would solve my problems but not yet ...
the block that I found is not presenting error...
find_bad_block
----------------
(514708,16)
(1 registro)
blockId / blocks_per_chunk = 514708 / 131072 = 3,9269104
base/21058/21271.3
chunk_block_id = block_id % blocks_per_chunk = 514708 % 131072 = 121492
is attached the result of pg_filedump -if -R 121492 /var/lib/postgresql/8.2/main/base/21058/21271.3
Even then I filled the block with zero
But when I run again the find_bad_block it show one block before, ctid 514707, and then, 514706 and I stop...
Any suggestion and explication?
