Re: [libvirt-users] libvirt, snapshots, LVM, and existing VMs
Thanks for the info. Those xml files will be invaluable.
How to create the logical pool, refer to:
http://libvirt.org/git/?p=libvirt.git;a=tree;f=tests/storagepoolxml2xmlin...
Looking at the pool-logical*.xml, pool-logical.xml will not harm an
existing data on disk, correct? Whereas pool-logical-create.xml will
attempt to create a new VG (and could cause data loss)?
How to create the logical volume with backing store, refer to:
http://libvirt.org/git/?p=libvirt.git;a=tree;f=tests/storagevolxml2xmlin;...
Since I already have LVM setup, and an active VG should I just omit
the following from my logical vol xml?
<source>
<device path='/dev/sda2'>
<extent start='31440502784' end='33520877568'/>
</device>
</source>
<capacity>2080374784</capacity>
<allocation>2080374784</allocation>
You can understand I'm somewhat hesitant to do this, as I don't want
to destroy or overwrite any existing data.
Best,
Casey
