This problem is related to the cman kernel module. The module has services connected to it, and therefore will not unload from memory. You can stop cman manually by: cman_tool leave force Or cman_tool leave force remove There is also a force flag on the cman start stop script. However this does not solve the problem of the cman kernel module! Hi Thanks Damjan, but I don't think so : what you write is true with CS U4 but no more with CS5 because cman seems to no more be a kernel module but in user space now. So ... ?
