We have a TrueNAS-13.0-U6.1 Core server, we’ve had the hardware a number of years, it was originally installed by the vendor, and we’ve not used it much.
But as it sits there with 130TB we want to use it to provision NFS datastore to VMware vSphere servers, we have used this server on and off over the years for NFS but it’s never been reliable, every now and then it just NFS stops responding to ALL (there are many ESXi servers) so it’s not just one, all these servers also connected to Synology NAS which do not show this issue.
So, we recently upgraded all the networking in the server to 10GBe, Jumbo Frames, fibre completed all the networking, as we suspected it could be the 1GBe.
and, we notice the same thing!
But this time, the GUI stopped working, NFS stopped working, and all we could do was power off and on again.
we don’t believe it’s hardware which is an Intel(R) Xeon(R) Bronze 3204 CPU @ 1.90GHz, 128GB, 130TB, 16 x HGST Ultrastar 12TB disks- RAIDZ2, 2 SSDs for OS.
Motherboard is a Intel S2600STB, J17012-600
There are no issues with the disks, all checked using Smart data, although having spent some time looking at the NAS, I’m surprised no cache for ARC and/or ZIL.
Any ideas, what to tweak of check.
I would expect the performance to be far better, than what we are experiencing with the specification compared to a Synology NAS.
