2.1. Linux Page Caching

For GNBD with device-mapper multipath, do not specify Linux page caching (the -c option of the gnbd_export command). All GNBDs that are part of a logical volume must run with caching disabled. Data corruption occurs if the GNBDs are run with caching enabled. Refer to Section 3.1, “Exporting a GNBD from a Server” for more information about using the gnbd_export command for GNBD with device-mapper multipath.
