[linux-lvm] How to "break-off" system disk mirror?

[Jon Price <jonelwoodprice gmail com>]

 

Hi,

 

If we use lvm to mirror our system disk and we are about to install patches, how to "break-off" mirror to have backout in case patches go awry?

 

Or can you point me to documents/procedures about this?

 

Thanks,

Jon
