Hi Mark,

Thank you for your answer. You are right, I have the following:

Mon Mar 16 11:02:24 EDT 2015: mounting /dev/gpfs2
Mon Mar 16 11:02:24.296 2015: Command: mount gpfs2
Mon Mar 16 11:02:24.723 2015: Disk failure.  Volume gpfs2. rc = 5. Physical
volume gpfs2nsd04.
Mon Mar 16 11:02:24.724 2015: Disk failure.  Volume gpfs2. rc = 5. Physical
volume gpfs2nsd12.
Mon Mar 16 11:02:24.723 2015: File System gpfs2 unmounted by the system
with return code 5 reason code 0
Mon Mar 16 11:02:24.724 2015: Input/output error
Mon Mar 16 11:02:24.725 2015: Failed to open gpfs2.
Mon Mar 16 11:02:24.724 2015: Input/output error
Mon Mar 16 11:02:24.725 2015: Command: err 666: mount gpfs2
Mon Mar 16 11:02:24.724 2015: Input/output error
mount: Stale NFS file handle
Mon Mar 16 11:02:24 EDT 2015: finished mounting /dev/gpfs2

But it is not mounted.

This is after issuing the "mmmount gpfs2" command

Mon Mar 16 11:03:52.010 2015: Command: mount gpfs2
Mon Mar 16 11:03:52.234 2015: VERBS RDMA connecting to 172.25.101.2
(heca2-ib0) on mlx4_0 port 1 id 4
Mon Mar 16 11:03:52.235 2015: VERBS RDMA connected to 172.25.101.2
(heca2-ib0) on mlx4_0 port 1 sl 0
Mon Mar 16 11:03:52.381 2015: Command: err 0: mount gpfs2

Now, my next step it to figure out how the clear the failure since it is
not failed anymore. The mmlsdisk reports all the nsd are up and ready.

One command I'm also looking for is a command to list which nsd server is
used for a particular nsd. I have a redundant config for which 2 servers
can access the same nsd. But I think that for some of them, the default
server is not used and the load of the servers is not distributed as wanted.
