As per DBRD guide block device or LVM could be used for data replication. However, whenever I try to create primary partition using fdisk all I get is following error.
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)
I also tried to make use of part probe but didn’t work out. If anyone have any idea, I will be thankful.
