I setup a pair of Fedora 17 VMs as per the "cluster from scratch" document and initially everything was working OK. Later I was trying to set the node IDs manually and accidently set two nodes to use the same ID. At this point the Corosync processes on both machines segfaulted. I understand that this is an invalid configuration but it seems dangerous that an existing cluster of devices can be interrupted by a new device with a duplicate ID. Would there be any interest in me raising a bugzilla entry with the backtraces etc? On both devices the crash occurs when the code hits a NULL pointer. First device: Program received signal SIGSEGV, Segmentation fault. 0x0000000000000000 in ?? () (gdb) bt #0 0x0000000000000000 in ?? () #1 0x000000000040cd7b in sync_barrier_handler (msg=0x7ffff5f53641, nodeid=1) at sync.c:236 Second device: Program received signal SIGSEGV, Segmentation fault. 0x0000000000000000 in ?? () (gdb) bt #0 0x0000000000000000 in ?? () #1 0x000000000040c5a7 in schedwrk_processor (context=<optimized out>) at sync.c:551 Jon
