X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 14 Jun 2004 10:42:11 -0000 We have a number of FreeBSD boxes with 7506 series 3ware controllers (about 10 and about to buy 10 more). We are generally happy with the performance and reliability, but we have a few intermittent, recurring problems. With some of our boxes we are using 300GB / 320GB Maxtor Maxline II disks. Occasionally, a machine with these disks will lock up hard; the 3ware controller has stopped responding. After taking the machine offline, and using MAXTOR PowerMax tools to analyse the disks, it becomes clear that one of the disks has errors. I have suspicions that the Maxtor disks are raising SMART events that are not handled by the FreeBSD 3ware twe driver. Is this a plausible explanation? Is anyone else aware of this issue, and is there anything we can do to solve / work around this problem? (We've tried disabling SMART on the disks - but the 7506 card re-enables it). More information: This is happening on at least 3 machines. The first time it happened, we upgraded to FreeBSD 4.10-PRERELEASE (cvsupped May 4th). This uses the 3ware imported drivers. (We also applied the stability patch posted to the Stable list in a bout of straw clutching). We have since seen the same problem on two additional machines (running 4.9-STABLE from Feb 2nd and April 4th). We haven't yet upgraded these machines - might do soon. I have sent an email to support@3ware.com - no response yet - but I only sent it last Friday. Thanks in advance, Jason.
