Josh Thompson updated VCL-846:
------------------------------
Component/s: web gui (frontend)
> Improve flow of handling nodes for deleted reservations assigned to new
> reservations
> ------------------------------------------------------------------------------------
>
> Key: VCL-846
> URL: https://issues.apache.org/jira/browse/VCL-846
> Project: VCL
> Issue Type: Bug
> Components: vcld (backend), web gui (frontend)
> Reporter: Aaron Peeler
> Fix For: 2.5
>
>
> As a user can make a new reservation, the front-end can assign a node that is
> currently being cleaned up from a deleted reservation. So far the states
> observed are:
> currentstate = pending
> laststate = deleted
> node state = reserved
> If this node is assigned to a new reservation, the back end checks for
> existing process, logs it and fails the new reservation. It fails it likely
> because the new process on the backend does not know how much time is left to
> clean up the deleted reservation.
> A decision/implementation on synchronizing the front-end and back-end needs
> to be made on how to handle this case as to not have reservation failures.
> Suggestions are to:
> 1) only select available machines not assigned to reservations on the front
> end.
> 2) Or on the backend - wait until the previous deleted process is complete(
> which could take a while depending on what can be done)
> 3) on the backend - intercept the process and force a reload - not matter
> what the image is.
