**Date:** 2026-02-18
**Disk:** /dev/sdd1 (ext4, label: data, ~3.6TB)
**Mount Point:** /mnt/data
**Samba Share Name:** Data

---

## 1. Create Mount Point

```bash
sudo mkdir -p /mnt/data
```

## 2. Configure /etc/fstab

The original entry had invalid options for ext4 (`uid`, `gid`, `iocharset`, `umask` are for NTFS/FAT only).

**Before:**
```
UUID=94a20060-e08f-40e4-b846-0f7a9398da04 /mnt/data ext4   defaults,uid=1000,gid=1000,iocharset=utf8,umask=022  0       0
```

**After:**
```
UUID=94a20060-e08f-40e4-b846-0f7a9398da04 /mnt/data ext4   defaults  0  2
```

## 3. Mount and Set Ownership

```bash
sudo mount -a
sudo chown jinsoo:jinsoo /mnt/data
```

## 4. Configure Samba Share

Added the following section to `/etc/samba/smb.conf`:

```ini
[Data]
   comment = EXT4 Data Drive
   path = /mnt/data
   browsable = yes
   read only = no
   guest ok = no
   valid users = jinsoo

   force user = jinsoo
   create mask = 0664
   directory mask = 0775
```

## 5. Validate and Restart Samba

```bash
# Validate config
testparm -s

# Restart Samba
sudo systemctl restart smbd
```

## 6. Access from Clients

| OS      | Address                        |
|---------|--------------------------------|
| Windows | `\\<server-ip>\Data`           |
| macOS   | `smb://<server-ip>/Data`       |
| Linux   | `smb://<server-ip>/Data`       |

## Notes

- Disk is nearly full (3.6T used / 3.6T total, ~9.7G free).
- Samba password was not changed; existing `jinsoo` SMB credentials apply.
- The share follows the same pattern as existing `[Backup]` and `[Database]` shares.
