Hi Is there any way to "lock" an active array? To make clear what I'm after: I have two machines forming a fail-over cluster connected over SAN to two storage boxes which provide them with a "disk" each. I created a RAID1 using those two "disks". Both cluster nodes see both disks but only one node, the active one uses them by assembling the array. During a fail-over I stop the array on the active node and assemble it on the node becoming active. It works OK, or at least I haven't seen any problems for quite a long time now. The problem now is how to prevent somebody on the other host from accidentally assembling the array. Because the result of doing so would be something from strange to catastrophic ;-) To rephrase my question, is there any way to make it visible to the other host that the array is up an running on the this host? Any comments, ideas? Thanks for your time.
