[Gluster-users] gluster volume status show second node is offline

[Strahil Nikolov]

No, it's not normal.Go to the virt2 and in /var/log/gluster directory you will find 'bricks' . Check the logs in bricks for more information.

I'm a novice with gluster. I have setup my first cluster with two
nodes 

This is the current volume info:

  [root at s-virt1 ~]# gluster volume info gfsvol1
  Volume Name: gfsvol1
  Type: Replicate
  Volume ID: 5bad4a23-58cc-44d7-8195-88409720b941
  Status: Started
  Snapshot Count: 0
  Number of Bricks: 1 x 2 = 2
  Transport-type: tcp
  Bricks:
  Brick1: virt1.local:/gfsvol1/brick1
  Brick2: virt2.local:/gfsvol1/brick1
  Options Reconfigured:
  performance.client-io-threads: off
  nfs.disable: on
  transport.address-family: inet
  storage.fips-mode-rchecksum: on
  cluster.granular-entry-heal: on
  storage.owner-uid: 107
  storage.owner-gid: 107
  server.allow-insecure: on

For now all seem work fine.

I have mount the gfs volume on all two nodes and use the VM into it

But today I noticed that the second node (virt2) is offline:

  [root at s-virt1 ~]# gluster volume status

What does it mean?
What's wrong?
Is this normal or I missing some setting?

If you need more information let me know

Many thanks for your help
