Package: mdadm Version: 3.4-4+b1 Severity: normal Trying to use mdadm to grow a raid5 array from 2 to 4 devices, I started it with the --backup-file argument to ensure integrity. This seems to have caused mdadm-grow-continue@...service to have failed:

Manually running mdadm --grow --continue /dev/md123 --backup-file ... got things running again. -- System Information: Debian Release: 9.3 APT prefers stable APT policy: (990, 'stable'), (500, 'testing'), (500, 'oldstable'), (490, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.9.0-4-amd64 (SMP w/12 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages mdadm depends on: ii debconf [debconf-2.0] 1.5.61 ii libc6 2.24-11+deb9u1 ii lsb-base 9.20161125 ii udev 232-25+deb9u1 Versions of packages mdadm recommends: ii exim4-daemon-light [mail-transport-agent] 4.89-2+deb9u2 ii kmod 23-2 mdadm suggests no packages. -- Configuration Files: /etc/cron.daily/mdadm changed [not included] -- debconf information excluded -- debsums errors found: debsums: changed file /lib/systemd/system/mdmonitor.service (from mdadm package)
