Date: Tue, 20 Feb 2007 19:35:00 -0000 [thread overview] Message-ID: <20070220193511.10957.qmail@sourceware.org> (raw) CVSROOT: /cvs/cluster Module name: cluster Branch: RHEL4 Changes by: jbrassow@sourceware.org 2007-02-20 19:35:10 Modified files: cmirror-kernel/src: dm-cmirror-client.c dm-cmirror-cman.c dm-cmirror-cman.h dm-cmirror-server.c Log message: Bug 217895: lost election results from cmirror server cause mirror ... There was a race happening as a result of simultaneous cman issued 'starts'. The client receives the start requests, but the server processes them. So, it was possible for the server to reset the event id/type while the client was trying to set them. This would cause the next kcl_start_done command issued by the server to fail. The bug can be interpretted many different ways depending on which machine in the cluster you are looking at when it happens. The fix was to have the client wait to set the event id/type until it knows the server has completed the previous request. This fix may resolve other bugs as well, but I will test them individually.
