ERROR: could not read block 4 ...
Hi, I'm getting this error:
2016-09-15 09:35:24 ART [13984-1] ERROR: could not read block 4 in file
"base/12210/11965": Error de entrada/salida

2016-09-15 09:36:09 ART [20704-1] ERROR: could not read block 4 in file
"base/12210/11965": Error de entrada/salida
To find out which database points to it I use:
mydb=# select oid, datname from pg_database;
oid | datname
-------+-----------
1 | template1
12210 | template0 <--- Looks like this is the problematic db
12215 | postgres
16384 | mydb
Two questions:
1) Is this caused by a bad block?, can fsck fix it?.
2) Is there a way to re-generate template0?.
Regards,

That looks like a hardware problem ... might want to budget for a new disk
sometime soon, before failures become more prevalent.
1) Is this caused by a bad block?, can fsck fix it?.
yes, and fsck is unlikely to help, though you could try.
2) Is there a way to re-generate template0?.
If you've never modified template1, you could drop template0 and re-create
it from template1. Otherwise, pg_dumpall/initdb/reload would seem to be
called for. A cautious person might want to do the latter anyway in case
there's more problems than just this one.

Thanks, indeed, I'm moving the Db to another server.
