How are disks removed on delete or migrate?
OnApp versions later than 3.0
Starting in the 3.0 version, it is possible to choose between format and wipe format (filling zeroes) when deleting or migrating a disk.
To enable disk wiping, you have to perform the following as root on your CP Server:
1. Set the wipe_out_disk_on_destroy parameter value to true in the /onapp/interface/config/on_app.yml configuration file
2. Restart OnApp service (service onapp restart)
The wipe_out_disk_on_destroy value is set to FALSE by default.
PLEASE NOTE: If you are using the lvwipe patch which was available for 2.x, you should remove this before enabling this feature under to 3.0.
