Thanks for the reply Guy...

I don't think this is necessary, as this space

  a) never had anything written to it, and

  b) will be used for LVM snapshots, so even if it had, it would get
     overwritten very soon.

Anyway, thanks... looking forward to getting my email rsnapshot backups 
working using LVM snapshots (for consistency - no more 'file vanished' 
messages during backups)...

Thx again
