Hi,
i have a "problem" with truenas 13-u1. testet on 12.x before and same happened.
My Hardware: Supermicro Storage Server with Xeon 6 Cores and 128gb of ram.
10x16TB HDD(data), 2xSSD(system)
Tested with Raid z1 or z2 with all of 10 drives and tested with 4 drives z2 and 3 drives z1, and with 3 ssd z1 via onboard controller to make sure that the HDD controller isnt the bottleneck.
All of this configuration tested against a server and a test workstation via 10gb ethernet, with iscsi share and smb.
Every time it starts very speeded up with 700mb/s to 900mb/s then after 5 to 10 minutes it brakes down, sometimes to 0kb, sometimes to 70-90mb/s and hold this speed for a while. after some minutes it speeds up most time to the first rates. And this is repeating evere 5-10 minutes.
when i make a stripe of 3 of these disks, without raid-z mode, nothing brakes down, only with raid-z level. what to do?
