We have a server with PERC H740P mini (embedded) and a 2 disk RAID 1 with EXT4 for the OS (CentOS 7.8) and a 6 disk raidz2 ZFS on Linux setup for the data, all on the same controller.
It's generally considered bad® to run ZFS with HW RAID, but this controller doesn't seem to support a mixed RAID/non-RAID setup, so the 6 data drives (for ZFS) are all single disk RAID 0.
We see occasional ZFS panics that I suspect are due to the RAID controller interfering. Where can I read about the exact semantics of single disk RAID 0 for this controller so that I might be able to determine if it is the cause?
Are there any perccli64 incantations or other debuggery I could use to see what the controller might have been doing when ZFS pooped the proverbial bed?
