Hello there.
I did something wrong.
I tried to get a disk out of a RAID5 with 8 hdds (4TB) to get a
Hotspare to change to RAID6 afterwards.
The RAID was clean and not rebuilding before I started.
The partition was only 11TB big. Not yet resized, because not created
with 64Bit, which I wanted to do afterwards.
Therefore I issued the following commands:
mdadm --grow -n7 /dev/md1 <-- just to get the size for the next
command.
mdadm --grow /dev/md1 --array-size 23441292288
mdadm --grow -n7 /dev/md1 --backup-file /var/backups/mdadm.backup
