DGM scenarios hit auto-failover on build 7.1.0-2179

Magma heavy-write throughput test hits auto-failover consistently on build 7.1.0-2179.

Node ('ns_1@172.23.97.29') was automatically failed over. Reason: The data service did not respond for the duration of the auto-failover threshold. Either none of the buckets have warmed up or there is an issue with the data service.

Disk usage worker is stuck on node "ns_1@172.23.97.26". Please ensure all mounts are accessible via "df" and consider killing any existing "df" processes.
