Table of Contents
RAID - mdadm - Convert a RAID 5 to a RAID 6
Do the Conversion
mdadm --grow /dev/md0 --raid-devices 4 --level 6 --backup-file=/root/md0-backup-file.bak
NOTE: Additional disks can also be added if the original RAID 5 had less than 4 disks.
mdadm --add /dev/md0 /dev/sdd1 mdadm --grow /dev/md0 --raid-disks=4 --level 6 --backup-file=/root/md0-backup-file.bak
- where –raid-disks=4: is the new number of disks.
Check that the conversion worked
mdadm --detail /dev/md0 cat /proc/mdstat
Update the mdadm configuraton file
Edit the /etc/mdadm/mdadm.conf file, such that the line spares=1 changed to spares=0.
