It sure looks like as of recently all builds are taking > 90 minutes. I think this is due to all builds repeating server kernel builds even if they don't need to. When no kernel builds get reused, no review build is fast. Backlogs grow quickly and empty out slowly. wondering if some recent change in master has stopped reuse of server kernel builds causing all builds to rebuild kernels and take too long. need TEI to look at recent builds. I'm suspicious of recent landing for I know for sure backlogs have been very large lately and it's still happening. My idea about the underlying cause is just a theory. Need somebody in TEI who is in a position to know or find out to investigate. |

Minh: if it is a lustre issue the breakage and the fix seems likely to be in lbuild or other build infrastructure, not in lustre code itself. Not sure who is a proper expert to deal with such a breakage. |
