About sharepoint mode in CloudStack
Hi, Can anyone help explain the difference of primary storage modes-- sharepoint and NFS? thanks, [email protected]
Re: Re: About sharepoint mode in CloudStack
Kirks, thanks a lot. By the wa y, I use OCFS2/iSCSI as the clumster filesystem under Shared Mountpoint mode. I have a problem right now. There are two hosts running ocfs2 and connecting to a signle storage server with iSCSI. After I run about one day, one hosts hung up and all the VM on this host stopped. I suspected ocfs2 filesystem locked the host. I want to see the lock status of ocfs2. How to do?

The NFS option should be used for NFS shares that are not already mounted on the hosts. CloudStack will tell the hosts to mount the NFS share you specify. The Shared Mount Point option would be for a primary storage that is already mounted on the hosts by the system administrator. Here is what the docs [1] say about it: > KVM supports "Shared Mountpoint" storage. A shared > mountpoint is a file system path local to each server > in a given cluster. The path must be the same across > all Hosts in the cluster, for example /mnt/primary1. > This shared mountpoint is assumed to be a clustered > filesystem such as OCFS2. In this case the CloudStack > does not attempt to mount or unmount the storage as > is done with NFS. The CloudStack requires that the > administrator insure that the storage is available.

difference of use ShareMount/OCFS2 and CLVM as primary storage of ClousdStack
Hi, Could any one help explain the difference of use ShareMount/OCFS2 and CLVM as primary storage for Cloudstack clusters? For ShareMount/OCFS2 mode, when there has problem for OCFS2 on a host, Cloudstack Manager does not know the situation and the VM on this host can not be migrated to other host. However, for CLVM mode, can the VM on the host be migrated to other host when CLVM of the host has problem? Best Regards, [email protected]
cloudstack-management switch over fail
Hi, In Cloudstack v4.2.1 There has two servers A, B. Both installed cloudstack-management service and mysql individually. Server A work as mysql master, and B works as mysql slave. step1: CS management service on A is running and management service on B shuts down. Mysql on B keeps synchronized with A timely. step2: Server A shutdown, means service of CS management and mysql on A shutdown. step3: CS management service on server B startup. But there has problem when it is starting up. The log is: "Error while decrypting: sTe567ED+dHX6WiWJWa53KdBSXQ0neJhKqcDENu7aMWqD2Z1JkXhYBm/7dKlIDpVpT6JdgecZPQ4jMge5Ldtx +7VUP8xjKoLn0EIxz85R30ePcMlDHw/Oy2SwkNM2HGQ " Then, user can not loggin.

Re: Re: cloudstack-management switch over fail
Hi, Geoff , Server B works as Master. The 'host' in global configuration is a VIP and the VIP is set to db.cloud.host(in db.properties) for both A and B. But there is till problem with following log: "2014-09-19 14:25:22,960 DEBUG [utils.crypt.DBEncryptionUtil] (Timer-2:null) Error while decrypting: SmVGNRd3CmQeMUHog+iSuQ== " I have one question for the cluster.node.IP in db.properties. What shoud it be? [email protected] From: Geoff Higginbottom Date: 2014-09-19 13:36 To: Subject: Re: cloudstack-management switch over fail Robin, You need to make server B the new MySQL Master and also point CloudStack at the new MySQL Server. Also when using two Management Servers, you should have a load balancer which is referenced by the global setting 'host'. If you do have this setup, you will need to update the host setting to point to server B, then stop and start (not simply restart) each system VM?
