Hello everybody!
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
   Status of volume: gfsvol1

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
