Hi guys
I've had an issue for some time now. When I'm copying a lot of files over to
ZFS usually using SMB it causes a panic and locks up the server.
I'm running FreeBSD 9.0-RELEASE with a custom kernel. I've just pulled
unnecessary drivers out of the config and added:
cpu HAMMER
device pf
device pflog
options DEVICE_POLLING
options HZ=1000
For full disclosure I am getting these errors in the syslog which means
there's an ECC error occurring somewhere which I am trying to locate. I have
replaced both of the CPU's and all of the RAM and am still getting it so
perhaps the north bridge has bought the farm.
We have some similar HW here and we suspect either CPU or Northbridge too,
we where seeing day to day panics and a scrub would pretty much guarantee
a panic.
We also replaced the CPU's with no joy but found disabling the cores of
the CPU in the second socket made the issues go away so strengthening the
Northbridge theory.
Try disabling the cores with the following and see if it helps:-
/boot/loader.conf
hint.lapic.1.disabled="1"
hint.lapic.2.disabled="1"
Unfortunately if you have perceived corruption due to this type of issue
there's no guaranteeing what state your data is really in :(
Regards
Steve
