Writes to NFS share cause TrueNas to go offline

[wsteyer]

I recently did a build

Asrock J5040-Itx motherboard
16GB of RAM
Using either
2x Toshiba N300 6TB mirrored
or
1x Samsung 840 Evo

For storage

Samba share works great.

NFS share has serious issues. Reads work fine, but writes cause serious problems. Writes seem to cause the TrueNas to stop responding. Sometimes I can't even access the management GUI until I reboot the server

If I check the dmesg on the client I get messages like
[78902.314870] nfs: server 192.168.0.78 OK
[79181.851548] rpc_check_timeout: 4952 callbacks suppressed
[79181.851550] nfs: server 192.168.0.78 not responding, still trying
[79181.851595] nfs: server 192.168.0.78 not responding, still trying
[79184.915531] nfs: server 192.168.0.78 not responding, still trying
[79184.915544] nfs: server 192.168.0.78 not responding, still trying
[79187.987599] nfs: server 192.168.0.78 not responding, still trying
[79187.987615] nfs: server 192.168.0.78 not responding, still trying

Where 192.168.0.78 is my TrueNas server.

When copying to the Samsung 840 Evo the server seems to die after less than 1GB of written data. That seems really wrong.

Is there something I need to tune in NFS to make this work?

Could be the Realtek NIC.
There are reports elsewhere in the forum.

SOLVED - TrueNAS's network crashes when huge the transfer traffic or the ZFS cache get top

I made a share folder with SMB, It is very frequency to crash the network. If found the log in /var/log/massages, that is the 're0: watchdog timeout '. My NIC is not Intel, I see many messages on the forums, My NIC Realtek RTL8111GR was not working well under FreeBSD. When the issue happened...

Yeah I was worried that might be the problem.

Although my system works fine with SAMBA and only seems to have problems with NFS.

Interestingly I tried enabling NFS support on a Windows box and writes from the Win10 system over NFS to the TrueNas Server worked fine, although I was only able to get around 50MB/s, so maybe slower writes work fine over NFS?

I was looking up Intel network cards on ebay assuming its the Realtek NIC.

Is the Intel X550 fully support under TrueNas including support for 2.5G?
