Hi I was just wondering if there was a plan to add 'Snapshot of a Snapshot' functionality to LVM2? If so, is there any timescale on it? This would be a very useful feature, especially in a Xen environment. Also, is there an easy way to backup and restore a snapshot? My scenario is that I am running several Xen DomU's (Virtual machines, 4 of them to be precise) from snapshots of a base image. However, if one dies (eg the snapshot overflows, something which should not happen again but just in case...) and I recreate the snapshot and restore the backup image I took, it fills the snapshot up. It doesn't seem to check if the data being written to the snapshot is the same as on the origin volume, just adds the data to the snapshot anyway. Is there any way round this (apart from the very slow script I currently have which checks each sector before writing)?
