I need a hand from a disk guru as I am having some problems with a 7000-2 mirror under 4.10. I last built the stable branch a couple of months ago. My 3ware Escalade 7000-2 has a pair of Maxtor 160GBs on it. I run them mirrored. The other day, a drive bit the dust. As the disk was well and truly hosed according to the Maxtor utilities, I chucked it and dropped a replacement into the RAID. The replacement disk was the exact same Maxtor model. (these were all cold swaps by the way, no hot swap cages here yet.) At boot I hit alt-3 to get into the 3ware BIOS and I started the array rebuilding. All seemed well. The 3dm web page indicated a rebuild was in progress. Disks were chugging. After a few minutes, the rebuild stopped and the 3dm web page showed "error." The console showed an unhelpful twe0 Disk Error message. - Is it still the case that a 7000-series 3ware cannot successfully rebuild under FreeBSD? I found year-old mailing list traffic that mentioned this, and suggested a Knoppix Linux live CD as a workaround. - Might a bad block in /usr kill the rebuild? a dump of /usr (single user mode) did show 2 read errors, which were accompanied by twe controller failure (0x40) error messages. However, the system did not display any other problems. Here is my 7000-2 version information, from 3dm. (which I now see is deprecated... do I need to install the 3ware CLI tools?) Monitor version: ME7X 1.01.00.036 Firmware version: FE7X 1.05.00.050 BIOS version: BE7X 1.08.00.046 PCB version: Rev3 Achip version: 3.20 Pchip version: 1.30-33 Model: 7000-2 Unit count: 1 Many thanks in advance for your ideas. With half a RAID I am running on borrowed time. At least a SMART probe of the remaining drive only shows 2 errors!
