This is where all of the lock state is stored. The lock state is what keeps the different nodes mounting gfs from corrupting data. You have no redundancy in the lock state. You stopped the lock server. The lock state was lost. The cluster cannot continue. The nodes killed themselves rather than let the filesystem meta data get corrupted. If you want to be able to stop lock servers, you MUST have redundancy in the lock servers. For gulm this means you need three nodes. -- Michael Conrad Tadpol Tilstra Gravity is a myth, the Earth sucks.
