Hello, CLVM is a way of using a network block device (eg iSCSI LUN) in a cluster-aware manner so you don't end up having multiple nodes using the same LVM volumes or updating LVM metadata and corrupting it. What it does is makes all nodes aware of the fact that the volume group on top of that LUN is used on multiple machines and the cluster software must be consulted before using it to make sure it's not used elsewhere. Shared Mount is a powerful option that enables you to use a filesystem that can be shared between nodes, e.g. you can take the above LUN and instead of "formatting" as CLVM you can put OCFS2 or GFS2 on top of it and use it like a clustered filesystem. Be advised this will probably be more complex to set up than CLVM and also less performant. Another example of using Shared Mount is mounting a GlusterFS volume as data stor, or CephFS, or XtreemFS or pretty much any network/cluster filesystem out there, if KVM can run off a qcow2 file off it then it's good enough for Cloudstack. How you would do it in practice is very simple: - on all hypervisors mount the desired filesystem/mounpoint in a path, e.g. /mnt/glusterfs, make sure it's writable etc - add the Primary Storage as Shared Mount point and when asked about the path input "/mnt/glusterfs" HTH Lucian -- Sent from the Delta quadrant using Borg technology!

Re: Cloudstack with iscsi storage
One more question, if i have a NAS and i have presented raw LUN to all my kvm hosts using iscsi, do i still need to setup clvm or can i just use iscsi target and cloudstack will use it as primary storage?

Re: Cloudstack with iscsi storage
Hi, I have configured clvm and when i try to setup cloud using cloudstack UI i didn't see any other options other than NFS at primary storage step, i am missing any thing? what are the other options i should get in drop down list? I am using cloudstack 4.3, centos6.5, please help. Ram On Sun, Apr 20, 2014 at 3:13 PM, rammohan ganapavarapu < rammohanga...@gmail.com> wrote: > Geoff, > > Thank you that is what i wanted to have.

Re: Cloudstack with iscsi storage
Geoff, Thank you that is what i wanted to have. I am planning to have NFS for secondary and CLVM for primary as cloudstack doesn't support direct SAN, not sure is there any other solution to present my SAN luns to all the VM hosts.

Re: Cloudstack with iscsi storage
Ram, The management server(s) need to have access to secondary storage, not primary. If you have placed your pri and sec storage devices on a common network (perfectly acceptable config) then you just need to ensure the management servers have access to the sec storage devices. Best practice has always been to restrict access to the pri storage devices to only the hosts within the clusters serviced by the pri storage.
