Formatting Thin Provisioning Volume...


Formatting Thin Provisioning Volume...

The format will usually be a soft or zeroing format, in which the controller writes zeroes to the data area and parity area, if any, of the LUN.
If we are formatting thin provisioning volume does it allocate all available space?

Thanks in advance...

Re: Formatting Thin Provisioning Volume...


Not sure what you are getting at but:

To totally erase a disk:

lvcreate a logical volume that completely fills it.

newfs a file system on it.

mount the file system

fill the file system with data.

umount the file system.

lvremove the logical volume.

Anything that was there is now gone.

The NSA could could still see what was there.

formatting thin provisioning volume is not a term I am familiar with.

It helps to have a common language with such questions.

Re: Formatting Thin Provisioning Volume...

The idea of thin provisioning is just that, make it look like the space and size are allocated but only allocate the space as it is needed. Are you asking if formating a LUN would force a thin provisioned allocation to become thick? It depends on your storage system which is a secret.
