| bzhao__ | johnsom: Hi, Micheal. I test with different heathmonitor.delay value, if I set it delay=1(misc_timeout=1), maybe the amp instance process the healthchecker so quick. I will find so many "Keepalived_healthcheckers[1216]: Process [2281] didn't respond to SIGTERM" in syslog, and there will be so many process to run the script when I exec "ps -ef". Then the realserver will be in DRAIN status(weight=0), as we config | 00:09 |
|---|---|---|
| bzhao__ | "misc_dynamic" in MISC_CHECK. The realserver side which running "iperf -s -p 2222 -u -V" will show the connect message from amp IP per healthmonitor.delay, if set delay=1(misc_timeout=1), realserver will hit "socket failed: Too many open files" and "bind failed: Bad file descriptor" soon. If set delay more than 4, I finally set it as 7, no error log found in syslog, the realserver will be recovered from DRAIN to | 00:09 |
| bzhao__ | ACTIVE(weight set back to we want), but through a long time, the realserver still hit the same issue above mentioned. I'm swimming in keepalived doc, not sure that is the right behavior. ;-( | 00:09 |
| bzhao__ | Oh the script doesn't support ipv6 yet, I miss it. ;-) | 00:09 |
| johnsom | Hmmm, just setting that delay higher may be just delaying the failure | 00:10 |
| johnsom | My worry is why it is not closing down | 00:10 |
| johnsom | It seems like -w1 is a one second timeout on the nc connection. So, yes, misc_timeout would need to be at least 2 | 00:13 |
| bzhao__ | johnsom: Yeah. I'm not sure if the connection should be cut down by real server, as lvs just can set the script timeout. | 00:16 |
| bzhao__ | johnsom: I reset the delay to 1, and remove -w1 manully. The realserver will be DRAIN again. Let me continue to deep into it for find the reason. ;-) | 00:28 |
| johnsom | Ok, sounds good. | 00:29 |
