Hello, Some question about PCS HA Cluster is not clear after reading http://kb.odin.com/en/119207 1) Can I just modify the config from one of cluster node or from MASTER node, and then distribute to all node? 2) If (1) is not and require to modify each node. Should I also need adjust the VERSION=X to greater number? 3) Need to restart any service after modify those parameters? 4) What is means of 'drs' with parameter RESOURCE_RELOCATION_MODE= 5) I tested with one of node crashed and the VPSs can be move to another node. Those VPS will be keep STOPPED and another node. However, when I checked by > shaman -c pcs top The VPS PWRR status is showing 'ON' and STATUS is 'ACTIVE'. Is there any something wrong config? Thanks!
Almost all these questions are well addressed in the documentation. Please check it beforehand. 1) config is global 2) - not relevant due to (1) 3) no 4) please refer to documentation http://download.cloudserver.odin.co.../Parallels_Cloud_Server_Users_Guide/37581.htm 5) The question is not quite clear, I might misunderstand you here. Configuration seem to be correct. If that is the only question here - nothing needs to be done. However, if relocation does not work as expected I'd recommend you to contact technical support for deeper investigation
Hello, Thanks. For 1), 2) & 3) is cleared once modify from MASTER node, it will update all node as well. However, while further details check using -v stat. It showing following error. Did you know how to resolve it? --- # shaman -c pcsnode -v stat New version config found: 4, current 1. Please, ugrade the shaman package. Failed to read XML model: syntax error ---- For 5), I guess is related to below http://kb.odin.com/en/124465 However, my case is container. Not VM. ***************************** New Question 6) when testing with iSCSI Example: I have two nodes 192.168.29.204 (simulate crashed) 192.168.29.206 (resource to be allocated) After 192.168.29.204 down --- # shaman -c pcsnode -v stat ISCSI ID STATE STATUS OWNER_IP OWNER_ID PRIORITY iqn.2014.06.com.parallels:store1 running Active 192.168.29.206 0ff06a1f313249c0 0 --- ISCSI can be reallocate to 192.168.29.206 But PORTAL IP is still keep using the old IP. -- # pstorage-iscsi list IQN STATUS LUNs HOST PORTAL(s) iqn.2014.06.com.parallels:store1 running 2 0ff06a1f313249c0 192.168.29.204 -- Finally I need to manual change the PORTAL IP. Does it normal? Thanks!
iscsi IP address must not be the same as the hardware node. It's an absolutely separate IP address you assign. Obviously upon relocation it won't be changed, it was never designed to work this way. Use separate IP address for iscsi target.
Hello, Just new question that is what happen if others active node did not have enough license to get all VM/CT back to online? Thanks!
they will remain in "broken" state/pool until node is back online Relocation over the license boundaries won't happen
