We are getting the below errors after 20 or 25 days of database creation.
ERROR: could not open relation 1919829/1152694/1921473: Read-only file system ERROR: could not read block 312320 of relation 1964206/1152694/1981329: Input/output error If we create a new database the problem is repeated after 20 or 25 days. Until then we don't have any issues with the new database. The size of database is very huge. We are loading millions of records every day and also fetching from the database is also high. Even the disks are not full. We are not dropping the old database. What is the reason for this issue? How can we ensure that it is not a database issue?

HighPoint is a pretty miserable RAID vendor--in the same league as Promise from what I've seen as far as their Linux driver support goes. In generally, and for reasons I'm not completely sure of, everyone selling "fake RAID" cards seems to be completely incompetent. The page at http://linuxmafia.com/faq/Hardware/sata.html hasn't been updated in a while, but as of 2007 all the current HighPoint cards were still based on closed-source drivers only. Completely worthless hardware IMHO. > Sounds like your hardware is bad. Could be mobo / cpu / memory or > RAID card.

In this case it seems more likely it's a drive failure though. -- Greg Smith 2ndQuadrant Baltimore, MD PostgreSQL Training, Services and Support g...@2ndquadrant.com www.2ndQuadrant.com -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general The INTERNET now has a personality.
