Hi Chen, What do you mean by "instantly get inode locked and teared down the whole cluster" ? Do you mean that whole disperse volume became unresponsive?
I don't have much idea about features.lock-heal so can't comment how can it help you. Could you please explain second part of your mail? What exactly are you trying to do and what is the setup? Also volume info, logs statedumps might help. ----- Ashish ----- Original Message ----- From: "Chen Chen" <[email protected]> To: "Ashish Pandey" <[email protected]> Cc: [email protected] Sent: Wednesday, April 13, 2016 3:26:53 PM Subject: Re: [Gluster-users] Need some help on Mismatching xdata / Failed combine iatt / Too many fd Hi Ashish and other Gluster Users, When I put some heavy IO load onto my cluster (a rsync operation, ~600MB/s), one of the node instantly get inode locked and teared down the whole cluster. I've already turned on "features.lock-heal" but it didn't help. My clients is using a round-robin tactic to mount servers, hoping to average the pressure. Could it be caused by a race between NFS servers on different nodes? Should I instead create a dedicated NFS Server with huge memory, no brick, and multiple Ethernet cables? I really appreciate any help from you guys. Best wishes, Chen PS. Don't know why the native fuse client is 5 times inferior than the old good NFSv3.
