Hi list,
I am working with 7.4.1 under Linux (SuSE 8.1) The server is a HP
ProLiant DL 380-G3, 2x Intel Pentium4-Xeon, 2.8 GHz, 4 GB memory and a
RAID 5 system with ca. 500 GB diskspace (xfs file system)
When doing big transactions or changes (UPDATE several million rows in
one step) on a database with ca. 50 GB diskspace and ca 15 million
entries, PostGIS and lots of indexes, I get errors like
ERROR: invalid page header in block 582024 of relation ...
The error does not occur regularly. It seems to me that the error is
related with heavy load and heavy I/O . CPU and memory does not seem the
problem, according to my hotsanic tools.
I have worked through
http://archives.postgresql.org/pgsql-general/2003-11/msg01288.phphttp://archives.postgresql.org/pgsql-admin/2003-09/msg00423.phphttp://groups.google.com/groups?hl=en&lr=&ie=UTF-8&threadm=20030922162322.E12708%40quartz.newn.cam.ac.uk&rnum=8&prev=/groups%3Fq%3Dpg_filedump%26hl%3Den%26lr%3D%26ie%3DUTF-8%26selm%3D20030922162322.E12708%2540quartz.newn.cam.ac.uk%26rnum%3D8
which suggest to me that I have run into hardware trouble (disk?
memory?!) But I supposed that my server was not SO bad for this database
application...
How to fix that? (I mean - not to repair the tables or pages but to get
a stable one? ) Trying another sotrage hardware?!
