Hi,
So I have a server (based on an Intel S2600GZ motherboard) that has 2 SAS ports. I cannot configure these ports to AHCI (only RSTe or ESRT2), but it seems that with RSTe, by default, the disk are directly usable by the OS.
I am able to get SMART values, S/N, ect. in FreeNAS.
Here is the dmesg (I tried to keep only the relevant parts)
The full version: https://pastebin.com/qKZ4SzWM
I know I could just buy a used LSI2008/230, but is it "safe" to use ZFS with this controller in RSTe mode without RAID?
Thanks,
