Hacim Silme¶
There are several ways to wipe a block storage device. The traditional way is
to set the lvm_type to thin, and then use the volume_clear
parameter if using the LVM backend. Alternatively, if the volume encryption
feature is used, then volume wiping is not necessary if the volume encryption
key is deleted. See the OpenStack Configuration Reference doc in the
Volume Encryption
section for set up details and also the Castellan usage document
for key deletion.
Not
Eski OpenStack yayınlarında, lvm_type=default silmeyi belirtmek için kullanılıyordu. Hala bu yöntem çalışsa da, lvm_type=default güvenli silme ayarlama için önerilmez.
The volume_clear parameter can be set to zero. The zero argument
will write a single pass of zeroes to the device.
For more information about the lvm_type parameter, see sections

and Oversubscription in thin provisioning
