Hi, I have a 3 nodes replica (including arbiter) volume with GlusterFS 3.8.11 and this night one of my nodes (node1) had an out of memory for some unknown reason and as such the Linux OOM killer has killed the glusterd and glusterfs process. I restarted the glusterd process but now that node is in "Peer Rejected" state from the other nodes and from itself it rejects the two other nodes

...It may be caused by tcmu-runner itself or glfs backstore handler so I will take similar tests with other handlers(like qcow) in order to find this point. If there's anything I missed, Could you give me some tips for resolving this issue? :-) Best regards. -- Ji-Hyeon Gim Research Engineer, Gluesys Address.

I have setup a distributed glusterfs volume with 3 servers. the network is 1GbE, i get filebench test with a client. refer to this link: https://s3.amazonaws.com/aws001/guided_trek/Performance_in_a_Gluster_Systemv6F.pdf the more server for gluster, more throughput should gain. I have tested the network, the bandwidth is 117 MB/s, so when i have 3 servers i should gain about 300 MB/s (3*117

Sometimes os disk hang occured and re-mounted with ro in vm guest(centos6) when storage was busy. After install vmware plugin, increased block response timeout to 30 sec. But os workload reponse time was not good. I guess my system composed with 5400 rpm disks with raid6. Overall storage performance is not good for multiple os images. best regards.
