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/pci0000:00/0000:00:1f.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. -- Package-specific info: --- mdadm.conf ARRAY metadata=imsm
