Case Workarounds

Spoiler: Config Error on Hero

Symptom:
CONFIG_ERROR(0) on LUN

Fix:
Edit file:

/etc/config/hero_zfs_lun.json

Before:

"status": 0

After:

"status": 1

Update firmware:

h5.0.0.1925_20220122 or newer

Spoiler: SMB Error – TDB Corruption

Applicable only for standalone or domain member.
NOT for Domain Controller.

Method 1:

/etc/init.d/smb.sh stop
rm -rf /share/CACHEDEV1_DATA/.samba/
/etc/init.d/smb.sh start

Method 2:
- Backup tdb files
- Delete corrupted files
- Restart SMB

Spoiler: SMB Login / RID Issue

Problem:
User RID exceeds NAS domain range

Steps:

1. Check login format
- Domain\\USERNAME or Domain+USERNAME

2. List users:

wbinfo -u

3. Get SID:

wbinfo -n DOMAIN\\USERNAME

4. Extract RID from SID

Example:

S-1-5-21-XXXX-XXXX-XXXX-305428740

User RID = 305428740

5. Backup configs:

cp /etc/config/uLinux.conf /etc/config/uLinux.conf.bak
cp /etc/config/smb.conf /etc/config/smb.conf.bak

6. Modify RID range:

File:

/etc/config/uLinux.conf

Before:

Main_Domain_Rid_Range = 10000001-20000000
Trust_Domain_User_Index = 30000001

Calculate:
New max = (user RID + min) rounded to nearest 10M

After example:

Main_Domain_Rid_Range = 10000001-320000000
Trust_Domain_User_Index = 330000001

7. Update Samba config:

/etc/config/smb.conf

Match new RID ranges

8. Restart service:

/etc/init.d/smb.sh restart

Notes:
- If log path missing → saved to /var/log
- Always backup configs before changes
