The kernel is detecting the partitions fine. Early in the boot, you see: hdd: hdd1 hdd2 hdd3 < hdd5 hdd6 hdd7 > It looks like there is an md-raid header on your disk, and md is claiming the entire disk, which appears to drop the partitions: md: md1 stopped. md: bind<hdd> md: raid1 personality registered for level 1 raid1: raid set md1 active with 1 out of 2 mirrors Kill off the md-raid header and you should be all set. (In reply to comment #1 from Jeff Mahoney) > Kill off the md-raid header and you should be all set. You're right - killing dm-raid fixed this (I have no idea how dm-raid got onto that disk). Thanks Jeff! Closing as INVALID |
