If I have a 2-nodes cluster with a clustered VG, that I copy (for example dd with cluster switched off), is then possible to acquire this VG on a third standalone node, or do I have to install the whole cluster layer on this third node too? This is on a rhel 5.2 server.... At the moment: pvscan is ok. pvscan PV /dev/dm-11 VG VG_TEST lvm2 [10.00 GB / 0 free] vgscan Reading all physical volumes. This may take a while...

Installing lvm2-cluster takes all sort of cluster infrastructure and probably licenses too... rpm -ivh lvm2-cluster-2.02.32-4.el5.x86_64.rpm warning: lvm2-cluster-2.02.32-4.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186 error: Failed dependencies: libcman.so.2()(64bit) is needed by lvm2-cluster-2.02.32-4.el5.x86_64 libdlm.so.2()(64bit) is needed by lvm2-cluster-2.02.32-4.el5.x86_64 rpm -ivh lvm2-cluster-2.02.32-4.el5.x86_64.rpm ../Server/cman-2.0.84-2.el5.x86_64.rpm warning: lvm2-cluster-2.02.32-4.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186 error: Failed dependencies: openais is needed by cman-2.0.84-2.el5.x86_64 libSaCkpt.so.2()(64bit) is needed by cman-2.0.84-2.el5.x86_64 libSaCkpt.so.2(OPENAIS_CKPT_B.01.01)(64bit) is needed by cman-2.0.84-2.el5.x86_64 libcpg.so.2()(64bit) is needed by cman-2.0.84-2.el5.x86_64 libcpg.so.2(OPENAIS_CPG_1.0)(64bit) is needed by cman-2.0.84-2.el5.x86_64 perl(Net::Telnet) is needed by cman-2.0.84-2.el5.x86_64 perl(XML::LibXML) is needed by cman-2.0.84-2.el5.x86_64 Thanks in advance, Gianluca
