[Gluster-users] How-to start gluster when only one node is up ?

[Remi Serrano]

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 at xxx ~]#  mount -t glusterfs 10.32.0.11:/gv0 /glusterLocalShare
Mount failed. Please check the log file for more details.

And when I check the volumes I get:
[root at xxx ~]# gluster volume status
Status of volume: gv0
Gluster process                             TCP Port  RDMA Port  Online  Pid

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
