Agenda

progress since last week

  • completed milestone review and sent out our plans.
  • total number of fs items is ~50

Chris highlighted the feedback he had already provided in email: he thought our progress advised that Recovery operations are an order of magnitude more complex.

AR: Richard to provide a list of the fs semantic operations that we will document.

getting to done with statfs

The complete task list is:

  1. integrate Chris's feedback on error codes
  2. highlight differences between MDT_STATFS and OST_STATFS op codes

Chris shared that from his reading the error codes don't look right. The call agreed that no further work should be performed on the hyperlinked sequence diagram and all efforts concentrated on completing the right level of detail.

initial discussion on state machine: our preference is file create

The call agreed that this was premature while the detail level was still being worked on.

closing comments

The closing comments from Chris and Colin were:

Process change needs to be made and code experts are not participating sufficiently to this project.
