Package: mdadm
Version: 4.1-1
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
I created a RAID 5 volume over 4 disks using the BIOS support for Intel
RST. Install proceeded correctly, however after a reboot in to the
installed system, the root device was not found. Investigation in the
init shell found that the mdamd device had not been assembled correctly
The following error was encountered when looking for imsm capabilies on
the controller.
mdadm --detail-platform
mdadm: imsm capabilities not found for controller:
/sys/devices/pci:00/:00:1f.2 (type SATA)
I found that this occurred when mdadm could not read from
/sys/firmware/efi/efivars/ due to it not being mounted. The efivarfs module was
not found in the initrd
To resolve this, I booted in to a rescue CD and added efivarfs and
efivars to /etc/initramfs.conf/modules and ran an update-initramfs
This allowed the system to boot correctly
I suggest that mdadm ensures that these modules are added to the initrd
when the RAID array is using IMSM.
