Hi all, i had a perfectly working 2-node cluster. I saw kernel security updates and cluster bugfix update, so i waited 2 weeks and decided, today, to do the updates I disabled my cluster service (oracle) , patched both machines and rebooted After reboot i had: [root@lvzbe1 kernel]# clustat Could not connect to cluster service and a bunch of Oct 13 13:51:55 lvzbe2 ccsd[3381]: Unable to connect to cluster infrastructure after 3840 seconds.

Can i download cman-kernel-src.rpm and dlm-kernel.src.rpm and compile myself, while waiting for answers from you ?

The cluster packages are kernel specific and lag behind normal kernel updates. Not sure if they release cluster updates outside the update cycle though, I haven't been using them for more than two updates. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
