Right, the metadata is being moved by the HPA, so when the kernel disables HPA, dmraid can't find the metadata any more. With default settings (Ubuntu 9.04, 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux since I didn't specify before), my drives both look like this: --- $> sudo fdisk -l -u /dev/sda Disk /dev/sda: 251.0 GB, 251000193024 bytes 255 heads, 63 sectors/track, 30515 cylinders, total 490234752 sectors Units = sectors of 1 * 512 = 512 bytes Disk identifier: 0xb782b782 Device Boot Start End Blocks Id System /dev/sda1 * 63 490207409 245103673+ 7 HPFS/NTFS ---- and dmraid can only find the metadata on /dev/sdb With 'libata.ignore_hpa=0' in the kernel command line, I get --- $ sudo fdisk -l -u /dev/sda Disk /dev/sda: 250.9 GB, 250999111168 bytes 255 heads, 63 sectors/track, 30515 cylinders, total 490232639 sectors Units = sectors of 1 * 512 = 512 bytes Disk identifier: 0xb782b782 Device Boot Start End Blocks Id System /dev/sda1 * 63 490207409 245103673+ 7 HPFS/NTFS $ sudo fdisk -l -u /dev/sdb Disk /dev/sdb: 251.0 GB, 251000193024 bytes 255 heads, 63 sectors/track, 30515 cylinders, total 490234752 sectors Units = sectors of 1 * 512 = 512 bytes Disk identifier: 0xb782b782 Device Boot Start End Blocks Id System /dev/sdb1 * 63 490207409 245103673+ 7 HPFS/NTFS --- with 2113 fewer total blocks on /dev/sda, and dmraid finds the metadata on both disks. -- intel isw raid metadata at odd offset https://bugs.launchpad.net/bugs/372170 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
