00:05 MacWinner are there any gotchas if you have multiple NICs on a server?  I wanted all my cluster traffic to go over a private LAN.. however I have a feeling maybe something is wrong with the interface selection.. when i do a gluster peer status, on node2, it lists the IP address of Node1, and the hostname of Node3
00:05 MacWinner on node3, it shows hostname for node1 and node2...
00:06 MacWinner on node1, it shows IP for node2 and hostname for node3
00:09 elyograg MacWinner: I think glusterbot has a info thing about this.  When you are doing your initial 'gluster peer probe' commands, just probe the first node (by hostname) from one of the others after you're done probing the rest, and it will fix the ip address into a hostname.
00:10 elyograg as long as DNS or /etc/hosts on all the nodes resolves to the right IP, it should communicate correctly.
00:10 elyograg I've got my servers communicating with each other on a different NIC - all the servers have the same /etc/hosts, and DNS has different IP addresses.
00:13 MacWinner hmm.. lemme check a little more
00:13 MacWinner my /etc/hosts is the same on all as well
00:17 badone_ joined #gluster
00:28 MacWinner elyograg, i'm looking at /var/lib/glusterd/peers
00:28 MacWinner and one of the peers has the publicIP listed as hostname1
00:29 MacWinner and the other has the hostname as hostname1…  i'm not sure how the IP got in there when I configured everything with hostnames
00:31 elyograg that's what happens when you first probe peers.  Just go to one of the other hosts and probe the first host.  If you've already created volumes, I don't know if this is a safe step.
00:32 elyograg I would guess that if you didn't use IP addresses when creating the volume, it will be safe, but don't do it on a production system unless one of the channel experts confirms it's safe.
00:39 elyograg or unless you can try it on dev hardware.
00:46 MacWinner elyograg, ,i tried the probe with teh volume already started, however the IP remains..i'll try to stop the volume
00:47 MacWinner is there any weirdness if you use a hostname without any dots like an fqdn?
00:47 MacWinner like if I use storage1 vs storage1.local
00:49 MacWinner elyograg, i stopped the volume and tried the peer probe, however it says peer is already in the list
00:49 MacWinner and it retains the IP rather than hostname
00:54 MacWinner strange.. i stopped the volume, and tried to detach the peers.. it gave me an error that the bricks of the peers are in the cluster.. however now the hostnames look correct.. i restarted volume and hostnames still look right
01:05 MacWinner wow.. i just tried to umount my /mnt/master on node3, and the box seems to have died..
01:05 MacWinner nto availabe via network anymore

01:49 MacWinner i'm trying to reset gluster into a clean state.. i've stopped and deleted all volumes.. however i still see remnants in /var/lib/glusterd/glustershd
01:49 MacWinner is there a clean way to get rid of everything?
01:49 MacWinner without reinstalling etc
01:56 mattappe_ joined #gluster
02:00 bennyturns MacWinner, rm -rf /var/lib/glusterd
02:00 MacWinner bennyturns, heh… btw, just figured out the slowness issue on the internal interface… looks like interface errors
02:01 bennyturns MacWinner, for you earlier question about nics
02:01 bennyturns you need GATEWAYDEV="my gateway dev" in /etc/sysconfig/network
02:01 MacWinner oh, what's that do?
02:03 bennyturns MacWinner, it specifies which device to use to hit the default gateway
02:03 MacWinner oh.. i see.. unfortunately that may not working since my gateway is thrhrough the public interface
02:03 MacWinner but i want gluster to use private interface
02:03 bennyturns I have mine setup:
02:03 bennyturns 10. pubilc
02:03 bennyturns 192. private
02:04 bennyturns my 10. are 1GB
02:04 bennyturns 192. is 10GB for storage
02:04 bennyturns all storage traffic is over 192
02:04 MacWinner nice.. which hosting provider do you use?
02:04 bennyturns my companies IT :)
02:04 MacWinner i only have 100mps..
02:05 MacWinner am thinking of upgrading to 1gb for gluster interface.. though I don't have that much storage activity

03:52 semiosis just getting back into the glusterfs java project after a few month hiatus, made a huge commit, and all tests passing in travis CI
03:52 semiosis feels real good
03:54 dbruhn congrats
03:55 semiosis thx
03:55 semiosis slow going but making progress
03:56 dbruhn Better than my contributions, I wish I had the ability to code so I could contribute more.
03:56 semiosis that wish is the first step, but yeah coding is time consuming
03:57 dbruhn I would need to have the free time to learn, which is one of the few things I seems to always be missing in life.
04:00 semiosis +1
04:12 dbruhn Hey do you have any idea why RDMA is broken in 3.4.1?
04:25 semiosis i've heard it is & i've heard it is not.  no idea at all
04:51 dbruhn hmm I guess to my test environment i'll have to go
04:53 mattapp__ joined #gluster
05:13 dbruhn is there something wrong with the download.gluster.org 3.3.2 repos?
05:29 vpshastry joined #gluster
05:33 semiosis @latest
05:33 glusterbot semiosis: The latest version is available at http://goo.gl/zO0Fa . There is a .repo file for yum or see @ppa for ubuntu.
05:33 semiosis dbruhn: which distro?
05:33 dbruhn redhat 6.4
05:34 semiosis i wouldn't know
05:34 dbruhn Yeah, ubuntu is your thing.
05:34 semiosis but unlikely imho

05:35 dbruhn I just pulled them down manually and installed them, but somethings up
05:36 semiosis careful, glusterbot will kick you for flooding!
05:37 dbruhn thought of that after pasting, sorry
05:47 semiosis sorry those errors dont make any sense to me

06:36 mikedep333 Hi, what happens if I create a replicated volume from 2 bricks: One empty, the other containing existing files and folders.
06:36 mikedep333 I am hoping that it will replicate them and let me access them through glusterfs.
06:37 mikedep333 I am using gluster 3.2 on CentOS 6.4 with Ext4
06:37 mikedep333 (both nodes are 64-bit)
06:51 purpleidea dbruhn: the repo shows 3.4 as latest for me. careful because centos has some gluster packages that are old too...
06:51 purpleidea or maybe they're in epel, but one of the two has old gluster.
06:56 mikedep333 yeah, I was wondering if I should upgrade to the newer glusterfs
06:56 mikedep333 from gluster.org's download link on the front page
06:57 mikedep333 oh, I'm getting them from EPEL
07:17 geewiz joined #gluster
08:01 mikedep333 well, EPEL hasn't updated their gluster packages since 2012-06-11
08:03 mikedep333 I'll upgrade to 3.4.1 from: http://www.gluster.org/download/
