[Gluster-users] Gluster questions - glusterfs 3.7.5
Correction : Version are glusterfs 3.7.5 Fra: gluster-users-bounces at gluster.org [mailto:gluster-users-bounces at gluster.org] P? vegne af Peter Michael Calum Sendt: 7. november 2015 14:11 Til: gluster-users at gluster.org Emne: [Gluster-users] Gluster questions Hi group, I'm new to Gluster, and still have a lot to learn.. I've build a 4 node setup for testing with Gluster 3.5.7 on CentOS 7.1.1503 (Core) an a replica 2 distributed volume optimized for VM's. - I have a RHEV 3.5 (Redhat Enterprise Virtuliazation) setup connected to my volume with NFS as a storage domain, and I have 3 test VM's running. I have 3 questions : 1 : If I reboot one of the cluster nodes it won't start the gluster up correctly. Gluster is started but RPC does dot run. I have tried to enable it with systemctl but it don't work. I have to start RPC manually and restart glusterd before the local NFS service in glusterd starts. - Does anyone have seen this problem ? 2 : I have tried to connect from RHEV 3.5 and create a storage domain with the GLUSTERFS protocol, but this is not possible, I get an error (Not possible to mount storage domain) In RHEV manager. I made a tcpdump and I can see that some version check is performed. Am I right it it could be the RHEV3.5 is build for Red Hat Gluster version and therefore has an earlier client version for gluster than 3.5.7 ? - Or are there backwards compability between clients and server ? - I think this could give problems in the future when upgrading RHEV or Gluster.. Maybe Ovirt is better to use with gluster. - What do you think ? 3 : Does anyone knows a good maintenance guide for gluster to handle daily maintenance tasks, like taking a node out of service, handling common errors, rebalancing and that kind of things.. Thanks for reading, kind regards Peter Calum -------------- next part -------------- An HTML attachment was scrubbed...

I am in the exact same boat. Well the front end is RHEL7.1 and the backend Ubuntu 14.04 LTS. What I have done however is mount using glusterfs. No idea which is faster, currently I am testing local disk v nfs v gluster to get a feel on the performance penalty of gluster. NFS using UDP might well be a good idea though if in reality it is indeed more fault tolerant? Yes I need an operational guide as well, if nothing is about I am just going to have to write myself one.
