Hello every one,
I have a huge problem. I started to grow a array with ( the added device
is /dev/sde )
# mdadm --grow --raid-devices=13 /dev/md0 --backup-file=md0.bak
after that there way 0 disk activity so i checked it with
# cat /proc/mdstat
everything looked fine but speed was 0K/sec for about 1-2 hours. I
decided to reboot the system as grow should continue after that. After
that the array wasn't assembled at all. So i wanted to do it myself:
# mdadm --assemble /dev/md0 /dev/sd[b-n] --backup-file=md0.bak --verbose
mdadm: looking for devices for /dev/md0
mdadm: /dev/sdb is identified as a member of /dev/md0, slot 0.
mdadm: /dev/sdc is identified as a member of /dev/md0, slot 1.

mdadm: :/dev/md0 has an active reshape - checking if critical section
needs to be restored
mdadm: No backup metadata on md0.bak
mdadm: No backup metadata on device-12
mdadm: Failed to find backup of critical section
mdadm: Failed to restore critical section for reshape, sorry.
Backup looks broken. What can i do ?

First make sure to use an overlay for testing: https://raid.wiki.kernel.org/index.php/Recovering_a_failed_software_RAID#Making_the_harddisks_read-only_using_an_overlay_file Try this https://raid.wiki.kernel.org/index.php/RAID_Recovery#Restore_array_by_recreating_.28after_multiple_device_failure.29 It worked so did on the real disks without overlay. Thanks to frostschutz, SwedeMike and djselbeck from irc ( #linux-raid on freenode ) for saving me. --- Viele Grüße, Daniel Koch Am 2015-08-14 11:22, schrieb Daniel Koch: > I crawled the archive of the list and found that --invalid-backup with > a faked and empty backup might help.
