regarding exported file system

[Mirror breaking]

Hi,
I have a 2 node MC Service Guard Cluster and Package file system is exported but it is not showing the exported file system in the secondary node.
Is it ok or I have any error.

well which node is the package running on?
if it is node1, then that node should have the file system exported, if node2, then it should be on node2, but not on both at tthe same time

Serviceguard does not present a file system across multiple nodes unless the CFS feature is installed (aka, Storage Management Suite - Cluster File System). Therefore, unless you have configured CFS packages, you should not expect a file system to be seen on more than one node in the cluster.

If you employed the HA-NFS package toolkit to implement the NFS-exported file system, then insure the volume group that contains the logical volume that contains the NFS file system uses the same minor number as the first server.

Example: Cluster comprised of nodes helix and torus
root:sg# remsh helix -e ll /dev/vgSG/group
crw-rw-rw- 1 root sys 64 0x020000 Mar 25 14:25 /dev/vgSG/group
root:sg# remsh torus -e ll /dev/vgSG/group
crw-rw-rw- 1 root sys 64 0x020000 Feb 29 11:22 /dev/vgSG/group

Note the minor number - 0x020000 is the same on both servers. If it is not the same on the 2nd server, export it, recreate the /dev/ and /dev//group file with the SAME minor number as node1 and reimport the volume group.
