I'm trying to get a two node GFS2 cluster running on a pair of test machines using GFS2 on top of a clustered lvm2 disk replicated over a DRBD 8.2.0 active/active link. After starting up drbd and cman, I attempt to start up rgmanager and clvmd and they both fail with this message in /var/log/syslog. Nov 13 22:25:36 seahawk kernel: dlm: process clurgmgrd (19787) version mismatch user (5.0.0) kernel (6.0.0) Nov 13 22:26:06 seahawk kernel: dlm: process clvmd (20143) version mismatch user (5.0.0) kernel (6.0.0) After trying to tune in various parameters to get more logging or debugging, apart from a somewhat uninformative strace, I can't seem to find a whole lot more about which userspace items are conflicting with which kernel space items. Oh, to make things a little worse, this is on a pair of Fedora FC6 machines rather than RedHat EL or CentOS. ---- Dan Brown dcmbrown@xxxxxxx -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
