I recently started seeing the following in the logs:
ERROR: could not read block 46 of relation
pg_tblspc/16385/8578554/11521501: Input/output error
CONTEXT: automatic vacuum of table "foo.pg_toast.pg_toast_8578780"
This is a Slony-I 1.2.21 slave, which runs 8.4.3 on RHEL 5.5.
This toast relation is the toast of an index of one of the most
frequently used tables.
Is this *definitely* a disk error, or could it be related to PostgreSQL
itself? I'm in the process of replacing disks, but I wanted to make
sure.
Regards,
