13:58 OERNii Hi, I have 2 gluster clusters. Both have same short hostnames gluster1,2,3. Only the domain and ip is different. Bricks are added as short hostnames only. Everything works inside each domain. Now I wanted to mount both cluster do different folders. My computer does cannot do that however as it cannot resolve the short hostnames. I can add these to /etc/hosts, but that only allows me to connect to one cluster. Any ideas how to access b

14:10 thoht_ is it safe to modify the IP ADDRESS Of my node having a gluster volume .???
14:11 thoht_ the gluster config is based on HOSTNAME; so if stop gluster; i modify IP and /etc/hosts to reflect the change; gluster should be happy at restart; right ?

14:33 JoeJulian wehde: pretty normal, yes.
14:33 JoeJulian ~mount server | OERNii
14:33 glusterbot OERNii: (#1) The server specified is only used to retrieve the client volume definition. Once connected, the client connects to all the servers in the volume. See also @rrdns, or (#2) One caveat is that the clients never learn of any other management peers. If the client cannot communicate with the mount server, that client will not learn of any volume changes.
14:33 JoeJulian OERNii: so once the configuration is retrieved, the client connects to the servers as defined in the volume.
14:34 JoeJulian The only way I can think of doing what you want would be to use containers that have their own hosts files.

15:33 paraenggu Hi there, I have an old 3.5.2 replicated volume consisting out of two bricks. One of the brick died and was replaced (only the lvm volume not the whole server). I'm now ready to start the failed and replaced brick. Before doing that, I would like to upgrade gluster to 3.5.4 on that server (as it's off-line anyway).  As soon as the self-heal finished, I would upgrade the other one. I'm wondering if this is a really bad idea, having one se

15:41 JoeJulian paraenggu: should be fine
15:41 kovshenin joined #gluster
15:42 paraenggu JoeJulian: OK, do you have experience with a similar situation?
15:44 virusuy joined #gluster
15:45 JoeJulian I've not done that specifically. As with anything, you should test it yourself. No new features are added for N within a 3.N release, so there won't be any unsupported features between those versions. Even if there were, op-version should protect from that. The metadata structure is stable between all the 3. versions, so you're good there.
15:47 paraenggu JoeJulian: OK thanks, sure I will test it first :) But it's always good to know in advance if it's a big no-go.

16:23 halloo With the recommendation of JoeJulian and dblack, I was able to upgrade my servers from 3.2. I went to 3.7.5-1.el6 from the upstream repository as I discovered that Gluster is no longer packaged with RHEL. I had to remove my 3.2 packages and just install the new version using the existing bricks, but everything seemed to come up.
16:25 halloo First question - is the gluster 3.6.0 client, which IS packaged with RHEL compatible with the 3.7.5 server?
16:25 halloo I'm talking about the native client, not NFS.

16:52 halloo Ok, so I need to get the 3.7.5 clients
16:52 JoeJulian the one packaed with rhel is "red hat storage" and is incompatible.
16:54 Pupeno joined #gluster
16:55 halloo Another question, is KVM / libvrt with GLuster storage stable and works?
16:56 halloo I currently use iScsi, but having live replication of disk images would be great
16:57 JoeJulian Yes, stable and works.
16:58 halloo what kind of performance hit would I see due to update replication?
16:58 JoeJulian Writes are bandwidth/replica_count. That's about it.
17:00 halloo i'll play around with it. So disk images are .img files? Is XFS or EXT4 recommended for the brick?
17:00 jwaibel joined #gluster
17:01 JoeJulian xfs is my recommendation
17:01 halloo cool, thanks. I'll play around with it.

18:11 wehde anyone get "commit failed on localhost" error with gluster vol status?
18:14 linagee can I expand the underlying storage (its lvm) without any bad effects?
18:14 linagee gluster works at the file level, right? so I should be good?
18:14 JoeJulian yep
18:15 JoeJulian I've done it many times.
18:15 linagee JoeJulian: thanks!
18:16 linagee JoeJulian: do you use restrict by IP or SSL in your own environment? (wondering if SSL is too much hassle?)
18:16 linagee (but IP makes me scared because user level could have problems, right?)
18:16 JoeJulian I do neither. I have private networks for storage.
18:17 JoeJulian If I were to restrict access, I would probably use iptables.
