Alright, here are some results.
Looking at my debug lines i can tell, that requesting either 2048 or 4 regularly fail. Other values don’t ever show up as failed, but there are several as you can see in the attached log.
The failed requests:
###
$ grep 'GD IOV-len FAILED' /var/log/kern.log | awk '{ print $9, $10 }' | sort | uniq -c
59 FAILED: 2048
64 FAILED: 4
###
I attached full debugging output from several executions of “megacli -ldpdinfo -a0” in 5 second intervals, successful and failed and content from /proc/buddyinfo again.
Can you make any sense of that? Where should i go from here?
