This is exactly the reason for the default 10% buffer between what we tell seastar it can have, and what we request for the cgroup with K8s. In one case we saw that the kernel was unable to allocate a TCP buffer, so it…
This should work fine. If you have any issues, please report as a bug.
The tuning isn't 100% necessary, it's there primarily for running max performance on metal, and you can pick and choose what to tune. In general it probably best to run with: --smp <n> --overprovisioned for a container…
This is not a hard requirement, but XFS is highly recommended for production.
