Hello, I try to get a RAID 5 array to assemble at boot with mdadm:
# mdadm --create /dev/md/test --level=5 --raid-devices=3 --write-journal=/dev/sde1 /dev/sd[bcd]1 mdadm: Defaulting to version 1.2 metadata mdadm: array /dev/md/test started. # /usr/share/mdadm/mkconf > /etc/mdadm/mdadm.conf # update-initramfs -u -k all update-initramfs: Generating /boot/initrd.img-4.9.0-4-amd64 # reboot After the reboot: # mdadm --detail /dev/md/test mdadm: cannot open /dev/md/test: No such file or directory This can easily be corrected with: # mdadm --stop /dev/md127 mdadm: stopped /dev/md127 # mdadm --assemble --scan mdadm: /dev/md/test has been started with 3 drives and 1 journal. The same works as expected when leaving out the journal option "--write-journal=/dev/sde1". The same issue occurs without a mdadm.conf file: # rm /etc/mdadm/mdadm.conf # update-initramfs -u -k all update-initramfs: Generating /boot/initrd.img-4.9.0-4-amd64 It does not work with the journal option, but it works without. What am I missing? Cheers, Tobi
