Hi @zhouzhifeisdcn. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

I don't think it's a good choice to hard-code it here, I think the main reason in your issue is that, volcano will automatically create podgroups for orphan pods, but you didn't specify schedulerName: volcano in your lws template. I think we'd better automatically inject schedulerName: volcano for lws needs to use volcano as the gang scheduler
