However, the LLD may loaded on multiple hosts, and they all see the same fake disk. Does the sd driver have any kind of built-in contention resolution mechanism for such multiple initiator setups? That is, if I mount a partition on my fake disk simultaneously on more than one host, how do I stop the filesystem from getting corrupted? Many thanks in advance. Dan Patton djp101@ecs.soton.ac.uk
