Hi folks: We have been trying to build an operational initrd for a root drive on software RAID1. Basic specs: 2.6.23.14 kernel (though same issues with 2.6.27.2 kernel), on Centos 5.2, pair of SATA drives using libata and other drivers, x86_64 architecture. Using mkinitrd --with=raid1 --with=libata --with=sd_mod ... I am getting a kernel panic on switchroot, it can't find the root file system. I did some googling, but could not find a similar example. Do I need to create a specialized init script? Is there an example of this somewhere? I did look at the Documentation/md.txt and tried the md=0,sda1,sdb1 md=1,sda2,sdb2 md=2,sda3,sdb3 kernel boot time option, to no avail. Persistent superblocks are on, and the devices have the right partition types. Any suggestions? More things to read? Thanks in advance.
