[gpfsug-discuss] Fail to mount file system

[Ilan Schwarts]

Hi everyone, I have received existing corrupted GPFS 4.2.2 lab and I
am trying to make it work.
There are 2 nodes in a cluster:
[root at LH20-GPFS1 ~]# mmgetstate -a

 Node number  Node name        GPFS state
------------------------------------------
       1      LH20-GPFS1       active
       3      LH20-GPFS2       active

The Cluster status is:
[root at LH20-GPFS1 ~]# mmlscluster

GPFS cluster information
========================
  GPFS cluster name:         MyCluster.LH20-GPFS2
  GPFS cluster id:           10777108240438931454
  GPFS UID domain:           MyCluster.LH20-GPFS2
  Remote shell command:      /usr/bin/ssh
  Remote file copy command:  /usr/bin/scp
  Repository type:           CCR

 Node  Daemon node name  IP address    Admin node name  Designation
--------------------------------------------------------------------
   1   LH20-GPFS1        10.10.158.61  LH20-GPFS1       quorum-manager
   3   LH20-GPFS2        10.10.158.62  LH20-GPFS2

There is a file system:
[root at LH20-GPFS1 ~]# mmlsnsd

 File system   Disk name    NSD servers
---------------------------------------------------------------------------
 fs_gpfs01     nynsd1       (directly attached)
 fs_gpfs01     nynsd2       (directly attached)

[root at LH20-GPFS1 ~]#

On each Node, There is folder /fs_gpfs01
The next step is to mount this fs_gpfs01 to be synced between the 2 nodes.
Whilte executing mmmount i get exception:
[root at LH20-GPFS1 ~]# mmmount /fs_gpfs01
Tue Jul  4 11:14:18 IDT 2017: mmmount: Mounting file systems ...
mount: mount fs_gpfs01 on /fs_gpfs01 failed: Wrong medium type
mmmount: Command failed. Examine previous error messages to determine cause.


What am i doing wrong ?
