Hi, we have an cluster with 7 machines with a SAN. We are using them to provide virtual machines, so we are using clvmd. At some point we are unable to access any of the pv/lv/vg tools. They are all stuck. From stracing them i've come to the conclusion that they are waiting for clvmd. Has anyone been in this situation? Thanks for any help, Nuno Fernandes in host xen1: Linux blade01.dc.xpto.com 2.6.18-92.1.17.el5xen #1 SMP Tue Nov 4 14:13:09 EST 2008 x86_64 x86_64 x86_64 GNU/Linux lvm2-cluster-2.02.32-4.el5 cman-2.0.84-2.el5_2.1 PID TTY STAT TIME COMMAND 20874 ?
