After upgrading a pretty big database (serveral hundred gig) from 8.2 to 9.2 I'm getting some "PANIC: could not
writeto log file" messages. Actually I got two of them. One yesterday and one today.
* postgres 9.2.1 is running on a windows 2003 server (downloaded the zip archive binaries) * Data is on an iscsi san
(thesame postgres 8.2 was running on perfectly since several years) * Full messages are :
PANIC: could not write to log file 118, segment 74 at offset 12189696, length 475136: Invalid argument
STATEMENT: COMMIT
PANIC: could not write to log file 117, segment 117 at offset 5660672, length 4096000: Invalid argument
STATEMENT: COMMIT
* I have no other messages from the san nor from windows
* Here are the non default parameters in postgresql.conf
listen_addresses = '*' # what IP address(es) to listen on;
max_connections = 200 # (change requires restart)
shared_buffers = 320MB # min 128kB
work_mem = 50MB # min 64kB
maintenance_work_mem = 700MB # min 1MB
checkpoint_segments = 15 # in logfile segments, min 1, 16MB each
Any idea on what might be going on ?
