Shalom,

Basically, you will have a floating IP address associated with a Serviceguard Package. This IP address will be running ont he active server, ie the server currently acting as the NFS share.

Your client connects to that address and is not concerned with the actual server the NFS package is running on.

The other important feature of the NFS package is that it exports disk on shared storage that both servers can access. This storage can be as simple as a JBOD device, Just a bunch of disks.

Hi,

I have no problem to configure NFS my main problem when I mount /data on primary node
LV[0]=/dev/vg01/lvol1; FS[0]=/data; FS_MOUNT_OPT[0]="-o rw"
when this file system mounted on node1
and the other node mount pkgIP:/data /data
when the node1 fail
LV[0]=/dev/vg01/lvol1; FS[0]=/data; FS_MOUNT_OPT[0]="-o rw" should transfer to the other node but we still have the mount point node1:/data /data unmounted
I try to commet the line #LV(0) ... in order to make to role of the packge just for VG activation, then when I execute
mount -F nfs pkgIP:/data /data it mount the file system with 2.5 MB while the lvol size 10 GB

Any advice,

Regards
