How-to start gluster when only one node is up ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

 

I setup a gluster file cluster with 2 nodes. It works fine.

But, when I shut down the 2 nodes, and startup only one node, I cannot mount the share :

 

[root@xxx ~]#  mount -t glusterfs 10.32.0.11:/gv0 /glusterLocalShare

Mount failed. Please check the log file for more details.

 

Log says :

And when I check the volumes I get:

[root@xxx ~]# gluster volume status

Status of volume: gv0

Gluster process                             TCP Port  RDMA Port  Online  Pid

------------------------------------------------------------------------------

Brick 10.32.0.11:/glusterBrick1/gv0         N/A       N/A        N       N/A

NFS Server on localhost                     N/A       N/A        N       N/A

NFS Server on localhost                     N/A       N/A        N       N/A

 

Task Status of Volume gv0

------------------------------------------------------------------------------

There are no active volume tasks

 

If I start th second node, all is OK.

 

Is this normal ?

 

Regards,

 

Rémi
