I'm trying to setup nightly snapshots of our VMs that exclude our attached storage. I've been looking into lvcreate but can't figure out how to make it pass over certain directories. Is this possible with this tool? I'm running CentOS.

  • You haven't really given any information. How are the VM's stored, and what 'attached storage' do you want to exclude? Are you asking 'how to take a snapshot of a single LVM volume?' – xrobau Jul 24 '17 at 23:09
  • My understanding is that our VM (16GB) lives on VMSAN adn the attached storage (2TB) is on compellent SAN. The attached storage doesn't appear to be mounted because it starts at /ourAttachedStorage rather than /mnt/ourAttachedStorage so I'm not sure how to describe it other than "attached storage". I'm looking to snapshot the entire system while omitting /ourAttachedStorage without having to deattach it first. @xrobau – G Warner Jul 25 '17 at 17:11
