SMB Shares

SMB Shares

The Linux Data Manager provides SMB (Samba) access to FSx Lustre storage for Windows clients.

Available Shares

Share Name UNC Path FSx Mount Size Description
gxp \\data-manager-linux...\gxp /mnt/gxp 1.2TB GxP-compliant data
odin \\data-manager-linux...\odin /mnt/odin 12TB Main HPC data
qcs \\data-manager-linux...\qcs /mnt/qcs 1.2TB QCS Navify data
ingest \\data-manager-linux...\ingest /mnt/ingest 9.6TB Kamino migration data

Full server hostname: data-manager-linux.odin.cluster.local

Connecting from Windows

Prerequisites

  • RDP session to Windows Data Manager
  • Your Samba credentials (same as Windows login)

Mount via GUI

  1. Open File Explorer
  2. Click This PC → Map network drive
  3. Select drive letter (e.g., G:, H:, I:, J:)
  4. Enter folder path: 
    \\data-manager-linux.odin.cluster.local\gxp
  5. Check Reconnect at sign-in
  6. Click Connect using different credentials if prompted
  7. Enter your username and password
  8. Click Finish

Mount via PowerShell

# Mount GxP data to G:
net use G: \\data-manager-linux.odin.cluster.local\gxp /persistent:yes

# Mount Odin HPC data to H:
net use H: \\data-manager-linux.odin.cluster.local\odin /persistent:yes

# Mount QCS Navify data to I:
net use I: \\data-manager-linux.odin.cluster.local\qcs /persistent:yes

# Mount Kamino ingress data to J:
net use J: \\data-manager-linux.odin.cluster.local\ingest /persistent:yes

Verify Mounts

# List all mapped drives
net use

# Browse mounted drives
dir G:\
dir H:\
dir I:\
dir J:\

Credentials

SMB authentication uses your data-manager account credentials:

Property Value
Username Your username (e.g., tsangc1)
Password Same as Windows login
Storage AWS Secrets Manager

Retrieve Password

aws secretsmanager get-secret-value \
  --secret-id odin/samba-users/YOUR_USERNAME \
  --query 'SecretString' \
  --output text \
  --profile odin | jq -r '.password'

Auto-Mount on Login

The Windows Data Manager is pre-configured to automatically mount the GxP share on login. Additional shares can be mounted manually using the commands above with /persistent:yes.

Data Flow

graph LR
    S3[(S3 Buckets)] <-->|Auto Sync| FSX[FSx Lustre]
    FSX -->|Mount| Linux[Linux Data Manager]
    Linux -->|Samba| Win[Windows Data Manager]
    Win -->|Drive| User[Windows User]

All data written via SMB shares:

  1. Lands on the Linux Data Manager
  2. Writes to the FSx Lustre mount
  3. Auto-exports to S3 (if DRA configured)

Performance Notes

  • SMB adds latency compared to native FSx access
  • For large file operations, prefer direct FSx access from Linux
  • SMB is optimized for Windows application compatibility, not throughput

Troubleshooting

Cannot Connect to Share

  1. Verify Linux Data Manager is running: 
    ssh data-manager-linux "sudo systemctl status smbd"
  2. Check DNS resolution: 
    ping data-manager-linux.odin.cluster.local
  3. Test Samba connectivity: 
    net view \\data-manager-linux.odin.cluster.local

Access Denied

  1. Verify your credentials are correct
  2. Check your user exists in Samba: 
    ssh data-manager-linux "sudo pdbedit -L"
  3. Reset password if needed (infrastructure team only)
