How to Prepare Disks for Replication on Azure

If working in Azure, review the following document describing how to attach a second disk to an instance.

https://docs.microsoft.com/en-us/azure/virtual-machines/linux/attach-disk-portal

Create /datakeeper Folder

*Note: After performing mkdir /datakeeper, change ownership to oracle.oinstall so that Oracle
setup can actually create database files. Run command: sudo chown oracle.oinstall /datakeeper

Check the Available Disks on node-a

Confirm the disk to mount using lsblk. As seen in the screenshot below, the storage device sdc is not mounted to the instance yet.

*Follow the Azure document above to mount it to the instance.

Use parted to prepare the partition, then use mkfs to prepare the file system.

Run lsblk again, now /dev/sdc1 should be available to mount.

Now you are ready to create the Data Replication Resource using LifeKeeper / DataKeeper.
