Hopefully this one's better. I'm trying to test the isw extension using ICH5-R SATA controllers. I have tried both RAID 0 and RAID 1, and so far haven't been able to discover any BIOS-configured arrays. From my debug prints it looks like the metadata handler couldn't find the config signature. I calculated the number of sectors and superblock offset by hand, and they seem to be correct. I also dumped the disk content at that offset, and it's all null characters. So now I'm wondering if: - I'm using an unsupported controller - I'm using unsupported BIOS - the metadata handler is looking in the wrong place - well, something else is wrong Here's some details on my setup: dmraid-1.0.0-rc2 Asus P4P800 mobo, ICH5-R controller hub, pair of 80 GB SATA drives SuSE 9.1 upgraded to 2.6.7 kernel with 2.6.7-udm1 patches device-mapper.1.00.19 Below is the output from running "dmraid -v -ay"(with some debug prints). I have a RAID 1 set up across /dev/sda and /dev/sdb. Failed to find sysfs mount point Carrying on with /dev/ checking for iswraid at /dev/sdb checking signature: total sectors: 0x000000000950e4c1 isw_sboffset: 0x00000012a1c97e00 looking for: Intel Raid ISM Cfg Sig. found: ---- checking for iswraid at /dev/sda checking signature: total sectors: 0x000000000950e4c1 isw_sboffset: 0x00000012a1c97e00 looking for: Intel Raid ISM Cfg Sig. found: ---- checking for iswraid at /dev/hda checking signature: total sectors: 0x0000000003effc10 isw_sboffset: 0x00000007dff81c00 looking for: Intel Raid ISM Cfg Sig. found: üÃÎ—ØQt³î®™Ò´W]5mqOÀ7~S}ÎóDvn@‹cüs ªÍA8 Çfyå0 ØÕyÁN„n5í®M†ÁÊÒw ¹²kx"éÕ{t° úÅGe!Š`1Û¼ß~žmÏCø-h@Áó5ôfJhÓ‘ uYÊæÀw~tÓ’Óíß2ÜnÒ?ð4 “)ggÔpRTqKØÔTãÓ©qÌÙ‹°Ö¡6@Ž¸ü9Ù_¤7¡œÙç@Mž¦e¥ƒ2ŸmR V±¿'…d|5)ëÂ#vˆ³™•´^e08šDB+Ù”ÿ#°‚OH×46IüËGV1(Œš¤†`YÓ>ãïøM,U(HÒéT’]ÈyÆÒ?u Ä+•ËÍ„‘NM_!

They didn't exactly match the signature string, tho. All replies most appreciated. Please let me know if more info is needed. Thanks, Jane </BODY> </HTML>
