seems, that the node is up n running from the OS point of view ..
so one can ping the node/ login the node...

but the /var/mmfs DIR is obviously damaged/empty .. what ever.. that's why you see a message like this..
have you reinstalled that node / any backup/restore thing ?

Sent by:        [email protected]




Is there a way to accomplish this so the rest of cluster knows its down?

My state now:
[root@cl001 ~]# mmgetstate -aL
cl004.cl.arc.internal:  mmremote: determineMode: Missing file /var/mmfs/gen/mmsdrfs.
cl004.cl.arc.internal:  mmremote: This node does not belong to a GPFS cluster.
mmdsh: cl004.cl.arc.internal remote shell process had return code 1.

 Node number  Node name       Quorum  Nodes up  Total nodes  GPFS state  Remarks   
------------------------------------------------------------------------------------
       1      cl001              5        7          8       active      quorum node
       2      cl002              5        7          8       active      quorum node
       3      cl003              5        7          8       active      quorum node
       4      cl004              0        0          8       unknown     quorum node
       5      cl005              5        7          8       active      quorum node
       6      cl006              5        7          8       active      quorum node
       7      cl007              5        7          8       active      quorum node
       8      cl008              5        7          8       active      quorum node


cl004 we think has an internal raid controller blowout_______________________________________________
