The DLM's lock_timeout should always be greater than cman's deadnode_timeout. A sensible minimum is about 1.5 times the cman value, but it can go as high as you like. > Another question : > is there somewhere a list of all parameters around CS4 that > we are allowed to tune ? This isn't exactly 'documentation' but it does briefly describe the cman tunables: http://sourceware.org/git/?p=cluster.git;a=blob_plain;f=cman-kernel/src/config.c;hb=RHEL4 -- Chrissie -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
