Package: mdadm Version: 3.3.2-5+deb8u1 Followup-For: Bug #806215 Dear Maintainer,
I've completed the questions in the template provided by reportbug below. * What led up to the situation? Ran full update and upgrade using apt-get at around 11AM on Tuesday, January 26th. Rebooted the machine and the problem occurred. * What exactly did you do (or not do) that was effective (or ineffective)? 1. Mounted the root drive using a Debian Stable LiveCD. 2. Commented out the line in /etc/fstab that mounted /dev/md0 to a folder in my home directory: /dev/md0 [HOMEDIR] ext4 noatime,noexec,rw 0 0 3. Rebooted the machine. 4. Re-assembled the RAID1 array using mdadm --assemble --force /dev/md0 /dev/sdb1,/dev/sdd1 5. Uncommented the line in /etc/fstab mentioned in step 3. 6. Mounted /dev/md0 to the original folder in my home directory using mount --all and confirmed that files could be read from the folder. 7. Rebooted the machine. * What was the outcome of this action? Same problem. /dev/md0 was not created, and mdadm made no apparent attempts to re-assemble the RAID1 array after logging in. * What outcome did you expect instead? I expected the RAID1 array to be created as /dev/md0 and mounted to the folder in my home directory that I designated in /etc/fstab. -- Package-specific info: --- mdadm.conf ARRAY /dev/md0 devices=/dev/sdb,/dev/sdd level=1 num-devices=2 auto=yes CREATE owner=root group=disk mode=0660 auto=yes HOMEHOST <system> MAILADDR root --- /etc/default/mdadm INITRDSTART='none' AUTOCHECK=true START_DAEMON=true DAEMON_OPTIONS="--syslog" VERBOSE=false --- /proc/mdstat: Personalities : unused devices: <none> --- /proc/partitions: major minor #blocks name 8 0 78150744 sda 8 1 248832 sda1 8 2 1 sda2 8 5 77899776 sda5 8 16 976762584 sdb 8 17 976761560 sdb1 8 32 5860522584 sdc 8 33 5860520960 sdc1 8 48 976762584 sdd 8 49 976761560 sdd1 11 0 1048575 sr0 254 0 77897728 dm-0 254 1 74690560 dm-1 254 2 3203072 dm-2 --- LVM physical volumes: PV VG Fmt Attr PSize PFree /dev/mapper/sda5_crypt doofwagon-vg lvm2 a-- 74.29g 0 --- mount output sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime) proc on /proc type proc (rw,nosuid,nodev,noexec,relatime) udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=1013494,mode=755) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000) tmpfs on /run type tmpfs (rw,nosuid,relatime,size=1638800k,mode=755) /dev/mapper/doofwagon--vg-root on / type ext4 (rw,relatime,errors=remount-ro,data=ordered) securityfs on /sys/kernel/security type securityfs (rw,nosuid,nodev,noexec,relatime) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k) tmpfs on /sys/fs/cgroup type tmpfs (ro,nosuid,nodev,noexec,mode=755) cgroup on /sys/fs/cgroup/systemd type cgroup (rw,nosuid,nodev,noexec,relatime,xattr,release_agent=/lib/systemd/systemd-cgroups-agent,name=systemd) pstore on /sys/fs/pstore type pstore (rw,nosuid,nodev,noexec,relatime) cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset) cgroup on /sys/fs/cgroup/cpu,cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpu,cpuacct) cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices) cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer) cgroup on /sys/fs/cgroup/net_cls,net_prio type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls,net_prio) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio) cgroup on /sys/fs/cgroup/perf_event type cgroup (rw,nosuid,nodev,noexec,relatime,perf_event) systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=22,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) mqueue on /dev/mqueue type mqueue (rw,relatime) debugfs on /sys/kernel/debug type debugfs (rw,relatime) hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime) fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime) /dev/sdc1 on /home/dnsullivan/library2 type ext4 (rw,noexec,noatime,data=ordered) /dev/sda1 on /boot type ext2 (rw,relatime) rpc_pipefs on /run/rpc_pipefs type rpc_pipefs (rw,relatime) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,relatime) tmpfs on /run/user/1000 type tmpfs (rw,nosuid,nodev,relatime,size=819400k,mode=700,uid=1000,gid=1000) --- initrd.img-3.16.0-4-amd64: 106904 blocks 131be8e959b59b6dc48c289966125cd4 ./sbin/mdadm d11fdf5c4dc36e493e12540b64cc8fc4 ./conf/mdadm 599bbf3fe6093157a26863dcb59cdf5d ./scripts/local-top/mdadm 1aa46962fd59231a7aef46f17ab354fd ./etc/mdadm/mdadm.conf d3be82c0f275d6c25b04d388baf9e836 ./etc/modprobe.d/mdadm.conf 07fb41218499d831672d6b87331863a1 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/linear.ko 3a02f53c60739a5549172206e0541c52 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/raid0.ko 6b258314b83f21d8d983b5e12d629fc0 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/raid1.ko b307708d878588b6c60de00ce5c0785a ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/dm-mod.ko 0fdf63c571b49d46d6daacc3f17352a6 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/dm-snapshot.ko d1d6ad3a8bce4cc570d66ed60b9ef856 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/multipath.ko 89c02e328dfbe555fa6dbf672dd3c74b ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/dm-bufio.ko c4a5688fca2b8f10229e19bb31a8c49e ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/raid456.ko a964933ab7158416c89b9af5549a6570 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/md-mod.ko ba20940aac01a8da2387912dceb15aa5 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/dm-region-hash.ko d667cfaecfa20795570916268c218d8d ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/dm-mirror.ko df0441dd71ce3fa45560ee097469a0b3 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/raid10.ko 0b1b51fdbbcacd9b145bd602d5a7c7ee ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/dm-log.ko 5137132a0856b16af280c0eeefea623c ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/dm-crypt.ko 38010a9345779caeb826363df5047b43 ./lib/modules/3.16.0-4-amd64/kernel/drivers/md/dm-raid.ko --- initrd's /conf/conf.d/md: no conf/md file. --- /proc/modules: dm_crypt 22595 1 -
