I have several XEN Servers that will use LVM as storage for the virtual mac= hines. After reading the Documentation (Logical_Volume_Manager_Administration.pdf = and manpages) i am not certain what to do about the mirror-log. I want the log to be as redundant as the data of the volume itself. Do i have to create a memory-logged logical volume and use that as the devi= ce for the disk mirror-log of the logical volume containing my data? Any suggestions would be greatly appreciated.
