00:03 JoeJulian @later tell dbruhn Yes, I'm back from summit, but now I'm at Norwescon with my family. Should be back to normal on Monday but until then I'm on and off.
00:03 glusterbot JoeJulian: The operation succeeded.
00:03 JoeJulian @ipv6
00:03 JoeJulian NCommander: there is... let me see if I can find that again.
00:04 NCommander JoeJulian, well, I actually fixed it except it appears Gluster is broken ina  pure IPv6 configuration
00:04 * NCommander does NOT have IPv4 available
00:04 NCommander (well, I do, but its useless for my setup)
00:04 NCommander It doesn't appear to look for AAAA records, and I haven't found it a way to feed it an IPv6 IP address
00:06 JoeJulian NCommander: http://www.gluster.org/pipermail/glu​ster-users/2013-November/037824.html
00:06 glusterbot Title: [Gluster-users] Hi all! Glusterfs Ipv6 support (at www.gluster.org)
00:06 * JoeJulian rages about documentation again...
00:06 NCommander JoeJulian, yup, found that, doesn't solve my problem
00:06 JoeJulian :(
00:06 NCommander I can confirm gluster is listening on tcp6
00:06 NCommander Its still looking for an A record which doesn't exist
00:07 NCommander JoeJulian, https://bugzilla.redhat.com/show_bug.cgi?id=922801 I dug this bug out of the bugzilla
00:07 glusterbot Bug 922801: unspecified, medium, ---, gluster-bugs, NEW , Gluster not resolving hosts with IPv6 only lookups
00:08 JoeJulian According to Vijay, he said you had to use addresses.
00:08 NCommander Which I get an error saying I need to use hostnames :-)
00:09 JoeJulian We had a discussion about this https://botbot.me/freenode/gluster/msg/12415610/
00:09 glusterbot Title: Logs for #gluster | BotBot.me [o__o] (at botbot.me)
00:09 NCommander That page 500s
00:09 JoeJulian on the "nice to have" list for 3.6
00:09 JoeJulian try again.
00:09 JoeJulian botbot's been bitchy today.
00:10 NCommander JoeJulian, ugh
00:10 JoeJulian yeah, my feelings exactly.
00:11 NCommander My setup is kinda whacky
00:11 JoeJulian I was even planning a changeover internally until this came up.
00:11 NCommander But basically I've got a very fugly webapp that requires consistent files frontend in Apache
00:11 NCommander with a daemon that generates that files that can only be one instance per network
00:12 NCommander I think the idea is you use NFS, but I detest single points of failure
00:12 JoeJulian amen
00:12 NCommander Honestly, I might have to setup ZFS ._.;
00:12 NCommander I looked at ceph, and it wants to run its own authetication system + SSH keys
00:13 JoeJulian If it were me, and I had those requirements, I would probably just do IPv4 over IPv6 to "get away" with it until 3.6 (6 months).
00:14 * NCommander twiches
00:14 NCommander We've got a small enough setup that I *could* do something like that
00:14 NCommander At least in the short term
00:14 NCommander I just don't want to redo the DNS to pt A records in
00:15 * NCommander went through a lot of pain to remove said A records and remove the internal NAT from bridging two clouds
00:16 JoeJulian Again, for a temporary fix, you could just use /etc/hosts.
00:16 NCommander Yeah
00:16 NCommander :-/
00:16 NCommander Thanks
00:16 NCommander That's extremely irritating
00:16 JoeJulian Make sure you add yourself to that bug.
00:16 NCommander JoeJulian, I'm registered on the bugzilla
00:17 NCommander If I can find some spare cycles, I might try and debug it
00:17 NCommander It looks like what I can do is if/when its fixed, resetup cluster, and install it as a new peer
00:17 JoeJulian I'm going to try to bug people about it too. I was hoping to go ipv6 only internally but this is a showstopper.
00:17 NCommander Well, I looked at the code
00:17 NCommander Its just a standard getaddrinfo()
00:18 NCommander But its not getting the AAAA record
00:18 NCommander Screw it, let me see if I can debug this
00:18 * NCommander *really* wants to avoid IPv4
00:20 NCommander Its looking for SOCK_STREAM ...
00:25 JoeJulian afaict, it looks like it fails to resolve a peer if the rdns doesn't also work... You should be able to tell if you run with debug logs.
00:25 NCommander JoeJulian, rdns works fine, we've got IPv6 Kerberos :-)
00:26 * NCommander however has bad thigns to say about writing reverse lookup files for IPv6
00:26 NCommander root@boron:~/src/glusterfs-3.4.3# host -r 2600:3c00::f03c:91ff:fe6e:1ded
00:26 NCommander d.e.d.1.e.6.e.f.f.f.1.9.c.3.0.f.0.0.​0.0.0.0.0.0.0.0.c.3.0.0.6.2.ip6.arpa domain name pointer hydrogen.li694-22.
00:27 DV joined #gluster
00:28 * NCommander breaks out gdb
00:29 JoeJulian what version are we looking at?
00:29 NCommander JoeJulian, 3.4.3
00:30 NCommander wtf
00:30 NCommander It only calls getaddrinfo once
00:30 NCommander on localhost
00:31 NCommander Breakpoint 1, __GI_getaddrinfo (name=0x5555555877e2 "localhost", service=0x5555557e1e60 "24007", hints=0x7fffffffde40,
00:31 NCommander pai=0x5555557e1e40) at ../sysdeps/posix/getaddrinfo.c:2329
00:31 glusterbot New news from newglusterbugs: [Bug 1025411] Enhancement: Self Heal Selection Automation <https://bugzilla.redhat.co​m/show_bug.cgi?id=1025411> || [Bug 1025415] Enhancement: Server/Brick Maintenance Mode <https://bugzilla.redhat.co​m/show_bug.cgi?id=1025415> || [Bug 922801] Gluster not resolving hosts with IPv6 only lookups <https://bugzilla.redhat.com/show_bug.cgi?id=922801>
00:35 NCommander ... this is odd ...
00:35 * NCommander doesn't see it ever call getaddrinfo () ...
00:35 NCommander except on localhost
00:42 NCommander hrm
00:42 NCommander The plot thickens
00:44 NCommander Breakpoint 1, __GI_getaddrinfo (name=0x7fffe80008e0 "hydrogen", service=0x0, hints=0x0, pai=0x555555997410)
00:49 chirino joined #gluster
00:49 NCommander JoeJulian, so it successfully navigates getaddrinfo() and *gets* the IPv6 address
00:50 NCommander and goes through the right case in get_ip_from_addrinfo
00:50 NCommander Value returned is $5 = 0x555555997380 "2600:3c00::f03c:91ff:fe6e:1ded"
00:50 NCommander And there's the IP
00:50 JoeJulian yep
00:51 NCommander *ip = gf_strdup (buf);
00:51 NCommander wtf?
00:51 NCommander Oh, it returns a string w/ the IP
00:52 diegows joined #gluster
00:53 NCommander JoeJulian, glusterd_friend_find_by_hostname returns 0; there's our breakage
00:55 NCommander JoeJulian, I found your bug :-)
00:56 NCommander JoeJulian, xlators/mgmt/glusterd/src/glusterd-utils.c:5007 calls inet_ntoa
00:56 JoeJulian Not my bug... I'm just a user. :D
00:56 NCommander That's IPv4 onlu
00:56 NCommander Gah
00:56 * NCommander thought you were a dev
00:59 JoeJulian Nah, I just hang out and BS with people about Gluster all day. I help as much as I can.
01:01 * NCommander pokes his head into #gluster-dev
01:07 bala joined #gluster
01:12 JoeJulian NCommander: fyi, if you want to submit a patch: ,,(hack)
01:12 glusterbot NCommander: The Development Work Flow is at http://www.gluster.org/community/docume​ntation/index.php/Development_Work_Flow
01:15 NCommander no love w/ this patch
01:19 JoeJulian Yeah, end of the day on a Friday after Red Hat Summit. Probably not a lot of devs going to be around until early in the morning on Sunday.
