Hi, Without qdisk (with two_node=1) cluster works fine. But I need qdisk for latest transition from 2 -> 3 nodes without cluster restart. Currently I built test cluster with the same hardware and reproduce this problem. Messages from dlm occurred from time to time, often I have no messages after "Quorum formed, starting" If I set clean_start=1, fencing start fine, but I still lock on access to cman_admin socket. So, if you have any suggestions or new devel. pakages for testing , I can install it and gather debug information. I can open official ticket for that, but since I installed unsupported packages this maybe wrong way :) But, without your unofficial packages I still have non-working qdisk and ccs_tool update ... PS I already tried to install new kernel from http://people.redhat.com/dzickus/el5/36.el5/x86_64/ (that contain many fixes in DLM) but without luck... -- Eugene Melnichuk Leading Engineer email: doc@xxxxxx mob: +380503304043 pbx: +380501105731 CJSC Ukrainian Mobile Communications 49/2 Pobedy ave., room 4.26, 03680, Kyiv, Ukraine Lon Hohberger пишет: On Mon, Jul 23, 2007 at 04:37:42PM +0300, Eugene Melnichuk wrote:I have problem with my cluster running on RHEL5 + updates from http://people.redhat.com/lhh/rhel5-test/ I have 2 node cluster with shared quorum disk, qdiskd is running, but when I start service cman I hang on Starting fencing.

Does this happen without qdisk? I don't understand why qdisk would cause this. |
