 | agents.​core.​capacity.​thin.​volumeCommitment | When creating replicas for an existing volume, each replica pool must have at least this much free space percentage of the volume size. Example: if this value is 40, the pool has 40GiB free, then the max volume size allowed to be created on the pool is 100GiB. | `"40%"` |
 | agents.​core.​capacity.​thin.​volumeCommitmentInitial | Same as the `volumeCommitment` argument, but applicable only when creating replicas for a new volume. | `"40%"` |
 | agents.​core.​logLevel | Log level for the core service | `"info"` |
+| agents.​core.​minTimeouts | Enable minimal timeouts | `true` |
 | agents.​core.​priorityClassName | Set PriorityClass, overrides global. If both local and global are not set, the final deployment manifest has a mayastor custom critical priority class assigned to the pod by default. Refer the `templates/_helpers.tpl` and `templates/mayastor/agents/core/agent-core-deployment.yaml` for more details. | `""` |
 | agents.​core.​rebuild.​maxConcurrent | The maximum number of system-wide rebuilds permitted at any given time. If set to an empty string, there are no limits. | `""` |
 | agents.​core.​rebuild.​partial.​enabled | Partial rebuild uses a log of missed IO to rebuild replicas which have become temporarily faulted, hence a bit faster, depending on the log size. | `true` |
 | agents.​core.​rebuild.​partial.​waitPeriod | If a faulted replica comes back online within this time period then it will be rebuilt using the partial rebuild capability. Otherwise, the replica will be fully rebuilt. A blank value "" means internally derived value will be used. | `""` |
+| agents.​core.​requestTimeout | Request timeout for core agents Default value is defined in .base.default_req_timeout | `nil` |
 | agents.​core.​resources.​limits.​cpu | Cpu limits for core agents | `"1000m"` |
 | agents.​core.​resources.​limits.​memory | Memory limits for core agents | `"128Mi"` |
 | agents.​core.​resources.​requests.​cpu | Cpu requests for core agents | `"500m"` |
