R50 NIC negotiation speeds/modes from 10G to 1G

[Aut0exec]

I have a Truenas R50 with 2 10Gb nics. I am having some ISCSI connection issues when I start my Veeam backups(no ping reply (NOP-Out) after 5 seconds; dropping connection). I think it is because the NIC is not negotiating to 1G from my Veeam server. I would like to manually change the NIC negotiation from 10G to 1G. I tried setting the mode by setting the ifconfig media but it did not work. How can I set this connection manually to 1G?

Autonegotiation is standard for 1G and 10G ethernet, as this involves auto-MDI/MDIX as well.

Have you actually verified that network connectivity is the problem?

Run a continuous ping and see if it is losing packets. It probably isn't, in which case trying to force a mediatype will not help. Most people with iSCSI ping timeout issues have other issues, such as having a RAIDZ pool, which isn't particularly compatible with iSCSI.

Hi jgreco, Thank you for chiming in. You are right... a continuous ping does not drop packets. I was just trying multiple things in an attempt to address my root problem which is issues with the iSCSI. During my Veeam backups is when I really get the issue. The drive that I have mounted would get very slow and I would get Truenas errors... "truenas WARNING: 192.168.3.6 (iqn.2005-10.org.freenas.ctl): no ping reply (NOP-Out) after 5 seconds; dropping connection” I had intended to use 10G from my Veeam to Truenas however my 10G card did not work out for me so I am using 1G on my Veeam server and 10G on my Truenas.

Do you have any recommendations to address this?

By the way... Please see my raidZ pool status below. Hope this helps...

Your question is so vague that it's nearly impossible to answer.

Please consider providing basic information about your setup.

Describe your FreeNAS system. This includes stuff like what sort of system it is ("TrueNAS R50" means nothing to most of the posters here --including me), what sort of CPU, how much memory, what kind of storage, how the storage pool is laid out, what sort of network controller, the network design, etc.

Describe your Veeam server and the role it is playing. Is it a bare metal Veeam proxy? Why are you using iSCSI instead of CIFS? Do you have problems if you use CIFS, which is the normal way for a Veeam proxy to access network attached storage?

You're presumably backing up PC's or virtual machines. Some brief explanation there might be helpful.

I have a suspicion that you're using RAIDZ and iSCSI; this is a match made in hell, in my experience. Specific discussion at this linked article:

https://www.truenas.com/community/threads/the-path-to-success-for-block-storage.81165/

If you are trying to use REFS/NTFS on top of iSCSI on top of RAIDZ so that you get the "benefits", it probably won't work out that way.

Hi jgreco,

Sorry for being so vague. Intel(R) Xeon(R) Bronze 3204 CPU @ 1.90GHz, 64G memory, 18 x 8T 7200RPM disk split between 3 vdevs in raidz2. 2 x 10GB nics. My Veeam server is a baremetal proxy and yes backing up VMs in my Vmware env. I didn't realize that using iSCSI would be an issue. I have no issues with CIFS. I will give that a go an see how that works out instead. Thanks much for your guidance.
