We are typically clustered so this isn’t a normal pattern for us.
You could create a backup of the contents stored on the removed disk by:
- Backup your aerospike.conf.
- In your aerospike.conf, replace the existing disk with the removed disk.
- Start Aerospike.
- Perform a backup of Aerospike.
- Once the backup finishes stop Aerospike.
- Restore your aerospike.conf and add the removed disk back into your list of devices.
- Now zeroize the removed disk.
- Start Aerospike.
- Now restore your backup.
