I believe this is a bug, but it may be I misunderstand how to cleanly bring up/down a whole cluster. I have a 3-node cluster, using today's CVS. I can bring it up fine, mount a gfs filesystem over iscsi on each node, then shut it down fine, using the procedures from useage.txt. However, if I then startup again without rebooting, when I get to clvmd -d , it will increase the active subsystem count, and fail with: Unable to create lockspace for CLVM Can't initialise cluster interface and the kernel log shows: dlm: Can't bind to port 21064 dlm: cannot start lowcomms -98 At this point the node that ran clvmd has an active subsystem count of one. Shutting down the cluster (using cman_tool leave force) and restarting it does not change this. Trying to run clvmd in this state causes the machine to immediately hang with no messages to the log or console. Fred
