Hi there,
I'll start off by saying that these hosts are all vmware instances that
I loaded up to do some testing, so if there's some known stability
problem running OpenBSD on vmware, let me know and I'll drop this. :)
In playing around with relayd on OpenBSD 4.3, I'm finding that it
crashes if all hosts become unavailable:
# relayctl show hosts
Id Type Name Avlblty Status
2 table webhosts:80 active
(1 hosts up)
4 host 192.168.33.31 100.00% up
total: 14/14 checks
3 host 192.168.33.32 disabled
3 table fallback:80 disabled
# relayctl host disable 4
relayctl: pipe closed
At that point, relayd is dead, and won't restart. /var/log/daemon shows:
fatal: flush_table: cannot flush table stats: Operation not supported
by device
and pfctl -a 'relayd/*' -sA shows:
relayd/www
I'm unable to restart relayd until I manually flush the anchor with
"pfctl -a 'relayd/www' -Fa", after which relayd starts up fine.
I get the same crash whether I disable the last host using relayctl, as
above, or if I just ssh over and stop apache on the last host (relayd
crashes on the next check). My apologies if this is already a known
issue, I tried to do my homework by searching the misc and bugs archives
as MARC, but didn't have any luck finding this precise issue (I saw
other mention of having to flush the anchors, which clued me in to that
bit so I could get relayd restarted...)
The relayd.conf I'm running when getting this crash, which is pretty
much based on the included example:
ext_addr="172.18.29.11"
webhost1="192.168.33.31"
webhost2="192.168.33.32"
webhost3="192.168.33.33"
errorserver="127.0.0.1"
interval 5
timeout 500
prefork 5
table <webhosts> { $webhost1 $webhost2 $webhost3 }
table <fallback> { $errorserver }
redirect www {
listen on $ext_addr port http interface vic0
# tag every packet that goes thru the rdr rule with RELAYD
tag RELAYD
forward to <webhosts> check http "/" code 200
forward to <fallback> check icmp
}
I'll put the dmesg from the relayd host at the end of this email.
Regards,
Mark
