dmesg | grep LSI returns...Good drives, a little aged and small on the cache side (16MB) but traditional CMR.
Unfortunately, these are SMR drives. Not guaranteed to be responsible, and don't have the known issues with sector IDNF that WD Red SMR does, but potentially a contributing factor if they are timing out commands under load.
May be an issue if it is behaving in RAID mode, still not as ideal as HBA330. Do you recall setting it to HBA Mode in the BIOS/EFI configuration?
dmesg | grep LSI
should hopefully pull out the line that's showing the driver being loaded. I expect to seemrsas
as the result.
