Hi, I'm trying to understand some cluster internals and would be happy to get some best practice recommendations:
monitor interval and timeout: shouldn't timeout value always be smaller than interval to avoid another check even though the first is not over yet? Additionally i would like to use the group function to put all my VMS (ocf:heartbeat:VirtualDomain) in one group and colocate the group with the VIP and my LVM-volume. Unfortunately group function starts the resources in the listed order. So if i stop one VM, the following VMs are also stopped. Right now I'm having the following configuration and want to make it less redundant: # never let the stonith_service run on the host to stonith location l_st_srv20 st_ipmi_srv20 -inf: srv20 location l_st_srv21 st_ipmi_srv21 -inf: srv21 # do not run resources on quorum only node location loc_r_lvm_vg-storage_quorum_only_node r_lvm_vg-storage -inf: quorum_only_node location loc_r_vm_ado01_quorum_only_node r_vm_ado01 -inf: quorum_only_node location loc_r_vm_bar01_quorum_only_node r_vm_bar01 -inf: quorum_only_node location loc_r_vm_cmt01_quorum_only_node r_vm_cmt01 -inf: quorum_only_node location loc_r_vm_con01_quorum_only_node r_vm_con01 -inf: quorum_only_node location loc_r_vm_con02_quorum_only_node r_vm_con02 -inf: quorum_only_node location loc_r_vm_dsm01_quorum_only_node r_vm_dsm01 -inf: quorum_only_node location loc_r_vm_jir01_quorum_only_node r_vm_jir01 -inf: quorum_only_node location loc_r_vm_jir02_quorum_only_node r_vm_jir02 -inf: quorum_only_node location loc_r_vm_prx02_quorum_only_node r_vm_prx02 -inf: quorum_only_node location loc_r_vm_src01_quorum_only_node r_vm_src01 -inf: quorum_only_node # colocate ip with lvm storage colocation col_r_Failover_IP_r_lvm_vg-storage inf: r_Failover_IP r_lvm_vg-storage # colocate each VM with lvm storage colocation col_r_vm_ado01_r_lvm_vg-storage inf: r_vm_ado01 r_lvm_vg-storage colocation col_r_vm_bar01_r_lvm_vg-storage inf: r_vm_bar01 r_lvm_vg-storage colocation col_r_vm_cmt01_r_lvm_vg-storage inf: r_vm_cmt01 r_lvm_vg-storage colocation col_r_vm_con01_r_lvm_vg-storage inf: r_vm_jir01 r_lvm_vg-storage colocation col_r_vm_con02_r_lvm_vg-storage inf: r_vm_con02 r_lvm_vg-storage colocation col_r_vm_dsm01_r_lvm_vg-storage inf: r_vm_dsm01 r_lvm_vg-storage colocation col_r_vm_jir01_r_lvm_vg-storage inf: r_vm_con01 r_lvm_vg-storage colocation col_r_vm_jir02_r_lvm_vg-storage inf: r_vm_jir02 r_lvm_vg-storage colocation col_r_vm_prx02_r_lvm_vg-storage inf: r_vm_prx02 r_lvm_vg-storage colocation col_r_vm_src01_r_lvm_vg-storage inf: r_vm_src01 r_lvm_vg-storage # start lvm storage before VIP order ord_r_lvm_vg-storage_r_Failover_IP inf: r_lvm_vg-storage r_Failover_IP # start lvm storage before each VM order ord_r_lvm_vg-storage_r_vm_ado01 inf: r_lvm_vg-storage r_vm_ado01 order ord_r_lvm_vg-storage_r_vm_bar01 inf: r_lvm_vg-storage r_vm_bar01 order ord_r_lvm_vg-storage_r_vm_cmt01 inf: r_lvm_vg-storage r_vm_cmt01 order ord_r_lvm_vg-storage_r_vm_con01 inf: r_lvm_vg-storage r_vm_con01 order ord_r_lvm_vg-storage_r_vm_con02 inf: r_lvm_vg-storage r_vm_con02 order ord_r_lvm_vg-storage_r_vm_dsm01 inf: r_lvm_vg-storage r_vm_dsm01 order ord_r_lvm_vg-storage_r_vm_jir01 inf: r_lvm_vg-storage r_vm_jir01 order ord_r_lvm_vg-storage_r_vm_jir02 inf: r_lvm_vg-storage r_vm_jir02 order ord_r_lvm_vg-storage_r_vm_prx02 inf: r_lvm_vg-storage r_vm_prx02 order ord_r_lvm_vg-storage_r_vm_src01 inf: r_lvm_vg-storage r_vm_src01 any help is greatly appreciated. thank you.
