I have two TrueNAS servers running 12-U2 (40 HDDs). They are in a domain controlled by a Windows 2016 Server as ADC . One server is running OK after some trouble with time sync to the domain. The other is giving me some trouble.
I am in the process of tidy up and rearrange my data and need to copy large amounts of data between the two servers. When I copy to one the server dies and behave erratic. After some search I have found that one of the disk controllers is resetting again and again . (Info on the device follows and the error message).
mps0: <Avago Technologies (LSI) SAS2008> port 0xe000-0xe0ff mem

mps0: IOCCapabilities: 1285c<ScsiTaskFull,DiagTrace,SnapBuf,EEDP,TransRetry,EventReplay,HostDisc
Note: The Controller is several years old but has been running without any problem for many years and my systems has 4 identical

I am of course afraid of destroying data as I do not know the nature of the IOC Fault.
I had no problems with this controller before upgrading to TrueNAS from FreeNAS but that can be a coincidence. I need to determine but I have no idea on how to debug this further. Any advice from some of u superusers?
