Hello,
*PROBLEM*
User's suspend VM/Instances in AWS at night and then resume them later.
Mostly this works great, but sometimes it fails. When it fails I will take
remedial actions and this fixes many things. I'll walk through the ACTIONS
below and ask for any feedback on what I could do differently or perhaps a
different order:
*ACTIONS*
To correct for instances stuck Resuming, or Rebooting:
1. *Firewall on Instance - * I'll check the firewall on the instance to
make sure I have open port 8008-8013 TCP as well as UDP.
2. *Soft Reboot Instance - * From the Scalr Interface I'll issue a hard
reboot. The results fall into three buckets
1. *Reboot Successful (Normal)* - The instance works now.
2. *Reboot (Resuming)* - The never seems to get out of the "Resuming"
state, but the AWS Console shows the instance running. Users are
learning
that they can just log in even when it says resuming. This is annoying.
3. *Reboot (NO Love)* - This system is not rebooting. I can go into
the AWS Console and start it up from there, but I have no method of
getting
things back in sync.
3. ?????
One other thing... mostly it's Windows system, but not all of them, not
even the majority of them. Maybe 1 in 10.
