Problem with using device as a file server

English General
1

Hi,

We have a TS-433 device using it as a file server. Here is the configuration of the device:

  • The filesystem used is EXT4.
  • The device is configured to be accessed only from a single machine.
  • Three 8TB HDDs are installed in the device with RAID5 configuration.
  • Two 1GbE ports are used in Balance-alb mode.
  • Snapshot is turned off.
  • Current firmware version is QTS 5.2.7.3256.

During the day, we observe that the device is intermittently not accessible and we observe the following messages on the client host when we encounter this issue:

[3008744.349010] nfs: server 192.168.x.yz not responding, still trying

[3008758.812960] nfs: server 192.168.x.yz not responding, still trying

It is weird but I noticed that the device becomes accessible when I log in to device control panel via the browser.

What happens if you only use a single Ethernet port?

Hi,

I need to check this. Did you mean just removing one cable while keeping the same mode, or disabling the port trunking and only using a single adapter?

4

Only use a single adapter.

Thank you for the clarification. Let me observe for 2 days to understand whether the issue is still ongoing.

Hi there, thanks for reaching out!

Could you clarify something for us: Is this a new device, or did it work fine before and just started having issues now?

To get you proper help, please open a support ticket with us. Our Support Team will take over from there and get things sorted. Thanks!

Indeed. :roll_eyes:

Hi,

This is a new device, and we directly enabled the port trunking when we installed the device.

After starting using only a single adapter, I have not observed this issue so far. Could you please clarify what is the reasoning behind this?

Good. That narrows it down a bit. :wink:

So the problem is with your trunking.

Please confirm: the original config was as-follows:

  • you have 2 x 1GbE connections from the NAS to your managed switch,
  • the NAS is aware both Ethernet ports are trunked,
  • your managed switch has 2 x 1GbE connections to the single client PC,
  • your managed switch has been made aware of the trunked ports,
  • the single client PC has 2 x 1GbE Ethernet ports,
  • the PC is aware both Ethernet ports are trunked.

Is this correct? Or are you using higher speeds like 2.5GbE?

Hi @OneCD,
It turned out that there was a misconfiguration on the switch. The problem is fixed now.

Thank you for your support on this.

Hi,

The problem occurred again, even using only a single network adapter. The QNAP device is intermittently not accessible, and becomes accessible from the client machine when I log in to QNAP device control panel via the browser.

12

Are the drives going to sleep? Do you hear them spin-up when you login to the QTS UI?

13

It is a bit hard to understand this. The QNAP device is located in a server room which is a quite noisy environment.

14

I also checked the status LEDs on the device. The ones that belong to disks are blinking in green color, and hence I assume that the disks are functional.

15

Is trunking still enabled but you are only using 1 physical NIC or did you remove the trunking configuration?

You also say it is configured for access from only 1 system, has you tried opening the list (ideally removing the restrictions completely) as a test?

Have you checked the system logs to see if there was anything that could have blocked access? A temporary lockout for example?

Trunk settings are removed from the switch configuration.

It is not possible, unfortunately.

Have you checked the system logs to see if there was anything that could have blocked access? A temporary lockout for example?

I only see the following diagnostic messages via the dmesg command:

[4321174.595588] nfs: server 192.168.x.yz not responding, still trying
[4321174.595590] nfs: server 192.168.x.yz not responding, still trying
[4321174.595592] nfs: server 192.168.x.yz not responding, still trying

Hi,

Is there a way to check the system logs on the QNAP device? It seems it is not possible to check those from QuLog Center.

18

What are you trying to look at? You can always download the logs from Help Center…That gives very detailed system logs but I am not sure if it will be decipherable for you…

19

My problem is still ongoing, and I need to understand if there is a service or kernel issue in the QNAP device.

20

I think it will be better to create a service ticket for this.
