Public bug reported:
While running automated array upgrade, my FC hosts become unresponsive
and / or stop logging . Sometimes the host stop logging to
/var/log/syslog, but I can still SSH into the host. Sometimes I try to
SSH to the host in the middle of the test and it'll prompt me for a
username that I then input, but it hangs there indefinitely and I have
to power cycle the host. Other times my host becomes completely
unresponsive and I can't SSH into the host and have to power cycle in
order to gain access again. I thought the host might be crashing, but
I'm not seeing any file get generated in /var/crash. I also thought my
hosts might be going to sleep or hibernating, but I ran "sudo systemctl
mask sleep.target suspend.target hibernate.target hybrid-sleep.target"
and am not seeing any improvements.
