I am looking for guidance on the recommend settings as I convert to shards. I have read most of the list back through last year and I think the conclusion I came to was to keep it simple. One: It may take months to convert my current VM images to shard’s, do you see any issues with this? My priority is to make sure future images are distributed as shards. Two: Settings, my intent is to set it as follows based on guidance on the Redhat site and what I have been reading here. Do these look okay? Additional suggestions? Modified Settings ===================== features.shard enable features.shard-block-size 512MB data-self-heal-algorithm full Current Hardware ===================== Hyper-converged. VM’s running Gluster Nodes Currently across three servers. Distributed-Replicate - All Bricks 1TB SSD Network - 10GB Connections Image Sizes – Up to 300GB Current Gluster Version ======================= 3.8.4 Current Settings ===================== Type: Distributed-Replicate Number of Bricks: 4 x 3 = 12 Transport-type: tcp Options Reconfigured: cluster.server-quorum-type: server cluster.quorum-type: auto network.remote-dio: enable cluster.eager-lock: enable performance.stat-prefetch: off performance.io-cache: off performance.read-ahead: off performance.quick-read: off server.allow-insecure: on performance.readdir-ahead: on performance.cache-size: 1GB performance.io-thread-count: 64 nfs.disable: on |
