I don't know if this is related, but something seems to be really wrong. I run the following set of commands: # dd if=/dev/zero of=ohase count=5K # dd if=/dev/zero of=ohase2 count=5K # losetup /dev/loop0 ohase # losetup /dev/loop1 ohase2 # mdadm --create /dev/md_d1 -ap --level=5 --raid-devices=2 /dev/loop0 missing # fdisk /dev/md_d1 (created one partition) # mkfs.ext3 /dev/md_d1p1 # mount /dev/md_d1p1 /mnt/test # echo jopajoo > /mnt/iso/test # mdadm --manage /dev/md_d1 --add /dev/loop1 # mdadm --grow /dev/md_d1 --raid-devices=3 --backup-file backupfile mdadm: Need to backup 128K of critical section.. mdadm: /dev/md_d1: Cannot get array details from sysfs Strace shows that it's trying to access "/sys/block/md_d4/md/component_size".
