Hi,
I was wondering if someone with more experience regarding mpath could
sheed some light on the following log entries;
Mar 19 23:36:25 myhost in.mpathd[34]: [ID 997829 daemon.info] probe
status 2 Fake probe reply seq 65535 snxt 0 on ce4 from 192.168.99.33

failure detection time 12855 ms
Mar 20 16:08:43 myhost in.mpathd[34]: [ID 122137 daemon.error] Improved
failure detection time 12855 ms
What would cause the Fake and Duplicate probes? Are they normal
messages that can be safely ignored?
Why failure detection time spike past 50,000 ms? Would it be due to an
interface running near capacity?
Thanks,
Leif
