Can I share a vg (for file system) on two nodes of a cluster?

[ljp_1]

I want to share a file system on two nodes by cluster set-up,how to do?

As far as I know you can only have the filesystem mounted on the second system as read-only. Have a look at this discussion.

Hi,

You can't share a file system between two nodes,whereas you can mount a file sysetm of one node to another

You can not activate a vg once it is activated on another node. That emplies neither can you mount a filesystem of a vg which is activated on another node.
The only thing you could do is do NFS mounts.

Hi,

You can share disks, but you cannot share a filesystem.

A VolumeGroup (included all lvols and filesystems) can only be activated on one node in the cluster?

But why do you want to do so? What's your intention?

Hi !
You can not share a file system between the two node , but you can create a volume group which can be shared by two nodes , both node can access that volume group at any given instant of time , then you can create file system on that volume gruop. The MC-Service guard allows you to share a volume group between the two nodes
