Re: Transport endpoint is not connected

Hi Ravi,

I think it probably is a firewall issue with the network provider. I was hoping to see a specific connection failure message we could send to them, but will take it up with them anyway.

Thanks for your help.

I don't see a "Connected to gvol0-client-1" in the log.  Perhaps a firewall issue like the last time? Even in the earlier add-brick log from the other email thread, connection to the 2nd brick was not established.

Hi Ravi and Joe,

The command "gluster volume status gvol0" shows all 3 nodes as being online, even on gfs3 as below. I've attached the glfsheal-gvol0.log, in which I can't see anything like a connection error. Would you have any further suggestions? Thank you.

[root@gfs3 glusterfs]# gluster volume status gvol0

Hello all,

We are seeing a strange issue where a new node gfs3 shows another node gfs2 as not connected on the "gluster volume heal" info:

[root@gfs3 bricks]# gluster volume heal gvol0 info
Brick gfs1:/nodirectwritedata/gluster/gvol0
Status: Connected
Number of entries: 0

Brick gfs2:/nodirectwritedata/gluster/gvol0
Status: Transport endpoint is not connected
Number of entries: -

Brick gfs3:/nodirectwritedata/gluster/gvol0
Status: Connected
Number of entries: 0


However it does show the same node connected on "gluster peer status". Does anyone know why this would be?

[root@gfs3 bricks]# gluster peer status
Number of Peers: 2

Hostname: gfs2
Uuid: 91863102-23a8-43e1-b3d3-f0a1bd57f350
State: Peer in Cluster (Connected)

Hostname: gfs1
Uuid: 32c99e7d-71f2-421c-86fc-b87c0f68ad1b
State: Peer in Cluster (Connected)


In nodirectwritedata-gluster-gvol0.log on gfs3 we see this logged with regards to gfs2:

You need to check glfsheal-$volname.log on the node where you ran the command and check for any connection related errors.
