Rick: In the previous 4.4.0-rc7 kernel build, i had the MD RAID driver was compiled as a module. However i have altered the kernel config and built it in the kernel monolith. Doing it this way also apparently enables the kernel to autodetect the raid array. Perhaps before it didn't load the MD module automatically and thats why it wouldn't mount your lvm2 root volume.... Just a guess. Hopefully i'm right?
I have changed the config in a new 4.4.0-rc7 rev2 test kernel deb package. Fingers crossed!
Haven't played around with a Powermac G5 (7.2) or lvm on linux before.
Progress — It looks like the builtin md autodetect is getting called, but it’s doesn’t seem to find anything… Or maybe it’s finding and assembling the array, but the LVM2 auto detect isn’t getting run?
In any case, JPG attached.
I’v also attached the output of dmesg after a successful boot of the 3.18.16 kernel, on the assumption that we want the console output from booting the 4.4.0 kernel to look something like it.
Examining the two leaves me wondering if the 4.4.0 kernel is finding the SATA disks /dev/sda and /dev/sdb. There’s no indication in the screen picture that it has. This would explain why it’s not finding the raid array — it’s not finding the components, so I can’t find the array…
Many thanks for all your help so far!
