We have noticed our performance deteriorating over the last few weeks, easily measured by trying to do an ls on one of our top-level folders, and timing it, which usually would take 2-5 seconds, and now takes up to 20 minutes, which obviously renders our cluster basically unusable. This has been intermittent in the past but is now almost constant and I am not sure how to work out the exact cause. We have noticed some errors in the brick logs, and have noticed that if we kill the right brick process, performance instantly returns back to normal, this is not always the same brick, but it indicates to me something in the brick processes or background tasks may be causing extreme latency. Due to this ability to fix it by killing the right brick process off, I think it's a specific file, or folder, or operation which may be hanging and causing the increased latency, but I am not sure how to work it out. One last thing to add is that our bricks are getting quite full (~95% full), we are trying to migrate data off to new storage but that is going slowly, not helped by this issue. I am currently trying to run a full heal as there appear to be many files needing healing, and I have all brick processes running so they have an opportunity to heal, but this means performance is very poor. It currently takes over 15-20 minutes to do an ls of one of our top-level folders, which just contains 60-80 other folders, this should take 2-5 seconds. This is all being checked by FUSE mount locally on the storage node itself, but it is the same for other clients and VMs accessing the cluster. Initially, it seemed our NFS mounts were not affected and operated at normal speed, but testing over the last day has shown that our NFS clients are also extremely slow, so it doesn't seem specific to FUSE as I first thought it might be. </div><div class=""><br class=""></div><div class="">I am not sure how to proceed from here, I am fairly new to gluster having inherited this setup from my predecessor and trying to keep it going.
