Hi,
I'm having a really weird issue with my NAS currently running FreeNAS 9.2.1.7 (had the issue in 9.2.1.6 as well) and would really appreciate some assistance as I'm running out of ideas.
The problem is that the NAS becomes unreachable from the LAN when under load (transfers via cifs and/or nfs), the issue can be reproduced at any time by just transferring a larger amount of data to the NAS and it usually only takes a few minutes until network connectivity fails. If I check my switch the ports are shown as UP. If I access the KVM console I can sometimes ping some of the other nodes on my LAN, not all of them but some which is extremely weird. In most cases pinging other nodes on the same subnet doesn't work at all and it outputs "No route to host".
* I have ruled out the switch (Zyxel GS1900-24E) and cables by connecting a workstation directly to the NAS with different cable. The issue remains.
* I have tried the second interface on the motherboard but it also fails. I have tested running link aggregation with LACP and both NIC's fails at the same time.
* I installed nas4free 9.2.0.1.972 on a different USB stick just to try another similar OS, I didn't manage to reproduce this issue in nas4free, It was 100% stable during load testing.
I compared the versions of the igb driver:
nas4free 9.2.0.1.972:
dev.igb.0.%desc: Intel(R) PRO/1000 Network Connection version - 2.3.10
FreeNAS 9.2.1.7:
dev.igb.0.%desc: Intel(R) PRO/1000 Network Connection version - 2.4.0
* FreeNAS logs says nothing when the network fails.
* Running /etc/rc.d/netif restart resolves the issue but the network will fail again after a while under traffic load.
The hardware specs:
AsRock C2750D4i
16GB Kingston ECC
IBM m1015 flashed with IT firmware.
8x4TB WD Red encrypted raidz2 pool. Running single 2TB WD Green during testing though.
ifconfig before failure:
ifconfig after failure:
Anyone else stumbled upon a similar problem?
Thanks in advance!
