Hi tom,

basically when i run any query with database say,

select count(*) from table1;

It gives me the following error trace:
WARNING:  could not write block 297776 of 1663/2110743/2110807
DETAIL:  Multiple failures --- write error may be permanent.
ERROR:  xlog flush request 7/7D02338C is not satisfied --- flushed only to 3/2471E324
 writing block 297776 of relation 1663/2110743/2110807
xlog flush request 7/7D02338C is not satisfied --- flushed only to 3/2471E324
xlog flush request 7/7D02338C is not satisfied --- flushed only to 3/2471E324\q

i tried using pg_resetxlog but till date, have not been able to solve this problem

Regards,
Vipul Gupta

This looks like corrupt data to me --- specifically, garbage in the LSN
field of a page header.  Is that all you get?  PG 7.4 and up should tell
you the problem page number in a CONTEXT: line.

                                                  regards, tom lane
