Subject: [linux-lvm] Snapshots and disk re-use
Date: Wed, 23 Feb 2011 12:36:12 +0000 [thread overview]
Message-ID: <4D64FF3C.6080602@abpni.co.uk> (raw)
Hi Everyone,
We host many Xen VMs for customers. We use LVM as the fisk storage for
these VMs. When a customer cancels, we generally dd their LV with
/dev/zero, before removing the LV.
If however we want to create a snapshot of a customer's LV, is there the
chance that the data may appear on a new future LV if we were to create
one (for a new customer)? Is is my understanding that most filesystems
don't actually remove data from a disk when deleting a file, but just
set an "ignore" tag of some sort...
Thanks
