how share a filesystem with MC/SG in r-w mode

[DIEGO_5]

Hi,

I must share a file system between two node in cluster but each other in read-write mode..Can I do that with LVM features?? How I can do??

Thanks all

Hi,

LVM don't allow you to share file system between two nodes.
If you want access to file-system on both nodes
you have to use NFS - one node has vg activated
and exporting fs to second node.

Hi,

I know nfs, but I do not need it, I want use a HA service, with MC/SG

Thanks
Bye

[Serviceguard for Linux]

Serviceguard on Linux does support LVM on the shared storage, but only one is enabled at one time. You cannot access the same LVM from 2 packages.

Diego,

LVM is not a choice for 2 nodes to have write access at the same time.

You've already ruled out NFS too, but this would be your only no-cost choice.

You might want to look at the Global File System from Red Hat, or Lustre. These are cluster aware file systems and allow concurrent multiple node write access.
