GlusterFS unable to add a new peer

  • 772

I am playing with / testing GlusterFS and I like it so far. I think I can put it to good use.

I setup 5 Virtual Machines on a server (this is just for the playing/testing part) and installed Ubuntu 12.04 Server on 4 out of 5 and Debian 64bit on the 5th.

1 is a client. 3x Ubuntu servers 1x Debian server.

I compiled gluster 3.3 from scratch on Debian as a test, I wanted to make notes and what not and to see how it went. The ubuntu boxes however are setup using apt.

The 3 ubuntu boxes are working fine. I have 3 Bricks in a stripe and it works great. The client can connect just fine and read/write data.

I am now trying to add the Debian peer to the first ubuntu server so that I can expand the stripe.

I can resolve the hostname, the FQDN and I can ping the ip address from all peers. I can telnet to the Debian machine on 24007 just fine. Yet when I try to probe it just sits there for a while and eventually just goes back to prompt and if I do a peer status I see:

Hostname: glusterfs-compiletest.domain.local Uuid: 00000000-0000-0000-0000-000000000000 State: Establishing Connection (Disconnected)

I have rebooted and restarted all the machines just in case.

No Firewalls at all. This is all on an internal server and I have made sure that there is no firewall (and again, I can telnet to the port)

Any ideas or anything I can try?

I am new to Gluster.

Thank you.

  1. Opening TCP port 24007 is not enough, as per http://gluster.org/community/documentation/index.php/Gluster_3.2:_Installing_GlusterFS_from_Source :

    Ensure that TCP ports 111, 24007,24008, 24009-(24009 + number of bricks across all volumes) are open on all Gluster servers. If you will be using NFS, open additional ports 38465 to 38467.

    Ensure they are open and available on the debian host. Moreover, are you trying to "probe" the debian host from an ubuntu one? You should issue the command from inside the active cluster.
