That was with FreeBSD 9.3, but I just updated my test system to 10.2, and it has been running the same stress test for 4-5 hours again with no issues. I don't doubt your experience at all, of course, but I wonder what is different? > > For what it's worth, my test machine is a Dell R610 with Dell TYVGC HBA (unclear whether this is a 9207-8e or 9205-8e), and WD Red drives in a Supermicro SC847 chassis. Just as an additional datapoint (this thread is giving me chills) with the LSI IT firmware version 20.00.02.00… * FreeBSD 10.2-RELEASE * Supermicro SC826 Chassis * LSI SAS2004 Controller mps0: <Avago Technologies (LSI) SAS2004> port 0xe000-0xe0ff mem 0xf72c0000-0xf72c3fff,0xf7280000-0xf72bffff irq 16 at device 0.0 on pci1 mps0: Firmware: 20.00.02.00, Driver: 20.00.00.00-fbsd mps0: IOCCapabilities: 1285c<ScsiTaskFull,DiagTrace,SnapBuf,EEDP,TransRetry,EventReplay,HostDisc> * LSI SAS2X28 Expander/Backplane ses0: <LSI SAS2X28 0e12> Fixed Enclosure Services SPC-3 SCSI device * 12x SATA WD RE 2TB drives (WD2000FYYZ arranged as 2x RAIDZ2 vdevs) Repeatedly filled up with data with regular scrubs without any issues and performance is pretty good, although I haven’t had a disk fail yet.
