Karios DFS
Distributed File System - User Guide
Karios DFS Overview
What Is Karios DFS?
Karios DFS is the storage management module of the Karios platform. It provides one interface to create, manage, and monitor file, block, and object storage across your cluster without command-line operations.
Who This Guide Is For
This guide is written for first-time Karios DFS users. It focuses on click paths, required fields, and expected UI outcomes.
Note
Any names, paths, sizes, and sample values shown in this guide are examples. Use values that match your environment, policy, and workload requirements.
Your User Role Matters
Role |
What You Can Do |
|---|---|
Administrator |
Full access: create, edit, and delete resources. |
Operator |
Create and edit resources; cannot delete. |
Viewer |
View and monitor only; no create/edit/delete actions. |
Note
If action buttons (for example, + Create Pool or + Create Export)
are missing or disabled, your role does not include that permission.
DFS Components

Object Storage |
Users, Gateway, and Buckets workflows. |
Infrastructure |
Hosts, Monitors, OSDs, Services, and Physical Disks. |
Monitoring |
Alerts, Performance, Logs, and Benchmark views. |
Advanced |
Configuration, Storage Topology (CRUSH Map), and Extensions (Manager Modules). |

Dashboard (Quick Health Check)
Path: Left sidebar > Karios DFS > Dashboard
Always check Dashboard before creating or modifying storage resources. Use Dashboard as the canonical health-check runbook.
Note
Dashboard numbers shown in screenshots are examples for reference. Your counts and usage values will reflect your own cluster state.
Before making changes, complete the four-step health check on the Dashboard page:
cluster health banner
OSD state
monitor quorum
raw capacity
Warning
Do not continue with storage changes until the Dashboard health check passes.
Recommended First-Time DFS Order
Review the canonical Dashboard health check.
Verify Infrastructure readiness.
Complete Storage workflows.
Continue with Block Storage/Object Storage workflows as needed.

Expected Outcome
After this section, you should be able to:
identify DFS modules and prerequisites
run dashboard health checks before changes
move through storage and dependent modules safely
