All, I'm pretty much up to speed implementing a tool "dmraid" (see design posting to linux-raid and linux-lvm), which is capable to activate various ATARAID sets on Linux 2.6 (eg, Promise FastTrak, Silicon Image Medley, Highpoint 45x) using device-mapper. I need help with these issues: o anyone who can send me Highpoint 37x metadata copies (sector 9 on each disk), disk geometry and size in sectors of all drives involved ? o anyone have reengineered LSI MegaIDE / MegaRAID sw-RAID metadata yet (last sector on each device) ?
