Hi there, This is my current shutdown script which works on some servers, not on others. /etc/init.d/httpd stop umount /var/www vgchange -aln /etc/init.d/clvmd stop fence_tool leave /etc/init.d/fenced stop cman_tool leave killall ccsd I run it... Deactivating VG VolGroup01: [ OK ] Deactivating VG VolGroup02: [ OK ] Deactivating VG VolGroup03: [ OK ] Deactivating VG VolGroup04: [ OK ] Stopping clvm: [ OK ] Stopping fence domain: [ OK ] cman_tool: Can't leave cluster while there are 4 active subsystems # cman_tool services Service Name GID LID State Code User: "usrm::manager" 13 6 run - [2 3 4 6 5 7 8] What's usrm::manager? I can't seem to find anything on the redhat site and online searches lead to endless 'stuff'. I'm guessing what ever this is, it's the problem?
