Question

After upgrading my RUTX14 firmware from 7.02.7 to 7.0.42 and reformatting my 4TB Seagate HDD to exFAT, (NTFS is no longer supported since 7.04)  everything seemed to work until I tried to create a new directory within the 4TB HDD filesystem via putty (or via Network Share ( Samba) ).  

I just made a test using a 16GB exFAT formatted USB stick works without any problem!!  

The RUTX freezes: WLAN doesn't work anymore, ( still visible, but impossible to reconnect).

The RUTX leds indicate normal state.  It seems that the RUTX reboots after a few minutes.

--> Hard reset required.

chkdsk on windows does'nt show any problems with the device. No problems to create directory using Windows.

There is no problem creating new files. Only creating directories forces RUTX14 to hang.

I wonder whether this is a (known?) bug or whether a 4TB exFAT device is just too big for the RUTX 

Under NTFS I didn't have any problems!!!!  

Any ideas?  Or do I have to stick forever with the old firmware????   Teltonik should consider supporting NTSF again.

Thanks in advance

Hello,

Switch to exFAT was made in order to reduce memory footprint of the firmware to leave more space for installing additional applications or user files.

Regarding your issue, could you try the following: login to the device via CLI/SSH, execute command logread -f, then create a new directory within your 4TB HDD filesystem via Network Share, and check, if there are any related log messages displayed in the terminal, before the the router freezes?

Maybe it would be possible to get some video of the issue, I would take it to the developers to investigate and find a solution?

Best regards,

_Hi,

_{thanks for the fast reply!}

logread doesn't show anything when exectuing the mkdir command. Also nothing written in a file via logread -fF command.

Everything I can send are the logfile entrys that appears on boot or reconnecting the USB device to the RUTX14:

Everything seems to be OK:  "Very big device. Trying to use READ CAPACITY(16)" indicates, that the device íst bigger than ca. 2 TB. The READ Capacity(16) doesn't seems to produce an error.  So the device should work.

I'am not an expert at all. Just googled the log statement....

Hello,

Would it be possible to get a troubleshoot file from the device, while the issue is present?

From the WebUI, the file can be generated from System -> Administration -> Troubleshoot page. However, if I understand correctly, the WebUI becomes unresponsive.

Could you try it via SSH? If you were able to login, execute the following command:

• troubleshoot.sh

This will generate a troubleshoot file. Now to extract this file from the router, please download WinSCP. Install and open.

Enter following session details:

• File protocol: SCP
• Hostname: 192.168.1.1
• Username: root
• Password: <routers_password>
• Press Login

Navigate to /tmp folder, you should find troubleshoot file. Move it to your PC and attach it by editing your question. 

Best regards,

Thanks again for your support!

It seems that there is no way to obtain the troubleshoot file:

WLAN doesn’t work after mkdir command!  Freeze; No access to the device, Reboot:–(

LAN doesn’t work after mkdir command! Freeze; No access to the device, Reboot :–(

Even access via RMS does not work after mkdir command! Freeze; No access to the device via RMS or RMS/CLI, Reboot :–(

Even reboot doesn’t work via the reset button: I always have to pull the power plug

Meanwhile, I tried a couple of things:

1.    Reformatted the 4TB USB disk (exFAT)  on a Windows PC

2.    Connected the 4TB USB disk to the RUTX14 and tested the empty disk after reformating via mkdir àworks perfectly, no problems!

3.  Reconnected the 4TB USB disk to Windows 11 PC and copied all 2.18TB data ( mostly MP4 files) again to the disks via Windows PC. (>100 directories and > 5000 files are created by Windows 11)

4.  Reconnected the 4TB USB disk to the RUTX14.

5. Tested the mkdir command: -> RUTX14 freezes

6.  Reconnect the 4TB USB disk to Windows 11:  everything works fine, there are no newly by RUTX14 created directories on the disk; --> no problem to create directories by Windows

The next step would be to buy another disk, but there is no evidence, that this invest of 100 Euros would give different results.

Actually, I decided to use the disk (USB network share on the RUTX 14) as a read only device to play MP4 videos via Amazon TV Stick on a TV in my camper - which was the main purpose -  and to skip the additional idea of using it to save photos and videos created during our trips to the disk via Samba network share until you reenable NTFS or find a solution to the problem.

Thanks again, I appreciate your very responsive support and I am still very happy with my RUTX 14 in my Camper!

Thank you for the positive feedback and detailed answers.

Could you at least attach troubleshoot file with your 4TB USB disk attached to the router?

I would still like to get this case investigated.

Hi,

You'll find the troubleshoot file attached to my initial question above. It was created with the 4TB USB HDD attached to the device.
