Very slow transfer speed Trunas scale 22.12.2 with SMB

[saebaryo]

Hello,

I have been reading some posts about the same issue of slow speed of transfer from SMB mounted drives to local disks, however the info was kind of confusing.
So my question would be: What are the tests I need to show to this forum here to have a precise diagnostic?

Speed using Ethernet or Wifi is almost the same (varies between 8 and 25 MB max).

PS: Using SMB and I have a Gigabit Intel i217 LM (Rev4)

Thanks!

Please post your full hardware specs, then output of zpool status in [CODE][/CODE] tags, the output of an iperf test in [CODE][/CODE] tags, tell us about your network and how you set up both the dataset and the SMB share, as well as about the files your are trying to transfer.

This should be a comprehensive list of the initial information needed. If you want more in-depth diagnostic you can run jgreco's solnet array and post its output in [CODE][/CODE] tags, you can find the link in my signature.

  pool: Pool

 state: DEGRADED

status: One or more devices has been taken offline by the administrator.

        Sufficient replicas exist for the pool to continue functioning in a

        degraded state.

action: Online the device using 'zpool online' or replace the device with

        'zpool replace'.

The first obvious problem is that you have a degraded pool... that's not going to be conducive to fast IO.

If that's the pool you're sharing from, I would stop there until you fix that and then continue the discussion if the problem persists afterwards.

 

[saebaryo]

As for iperf I don't seem to have it and when I try to install it using sudo apt-get install iperf, the command is not found.
Regarding my network, I am using a router with Fresh tomato FW, from which I am connecting a Gigabit switch and from the switch I connect a Cat6 cable to the Trunas.
I have 2 pools, One used to have 3 disks and another 1 disk, then recently I removed one disk from the main pool and added it to the secondary pool to have a mirror for that pool.
When I did that it became logically degraded but even before that the speed was very slow, this did not affect the speed.

As for Data sets:

Pool1:
Type:FILESYSTEM
Sync:STANDARD
Compression Level:LZ4
Enable Atime:ON
ZFS Deduplication:OFF
Case Sensitivity:ON
Path:Poolassignment

Pool2:
Type:FILESYSTEM
Sync:STANDARD
Compression Level:LZ4
Enable Atime:ON
ZFS Deduplication:OFF
Case Sensitivity:ON
Path:Pool-2tb

It shows also that the Dataset in the first pool is "used by the system".

Thx! I replied to your question I guess for the degraded part :)

You shouldn't use apt on the appliance os host.

iperf3 is what you're looking for (and it's already installed).

When I did that it became logically degraded but even before that the speed was very slow, this did not affect the speed.

It will very much be impacting the speed (I guess you may only discover that when you fix whatever other problems you have).

Being over 80% full won't be helping much with write speeds either.

The speed has always been slow before removing the disk an after

Regarding iperf3 I used the command I was not familiar with it tbh. Shall I start the server on Trunas with iperf3 -s and then use iperf3 -c myserveip from my client machine?

Exactly. You can also use -bidir on the client end to get a test in both directions at the same time.

Do I need to open ports to have it work? On the server it is listening on 5201 and client showing 5001.

Client:

Code:

iperf -c 192.168.1.29
tcp connect failed: Connection refused
------------------------------------------------------------
Client connecting to 192.168.1.29, TCP port 5001
TCP window size: -1.00 Byte (default)
------------------------------------------------------------

[LarsR]

you need to use the port of the iperf server. you can specify it with -p 5201.

[sretalla]

68.2 Mbits/sec

That's not even 100Mbits... that will need to be investigated if you're going to hope for faster transfers.
