Hi, We have a set of 4 gluster nodes, all in replicated (design?) We use it to store our qcow2 images for kvm. These images have a variable IO, though most of them are for reading only. I tried to find some documentation re. performance optimization, but it's either unclear to me, or I couldn't find much.. so I'd copied from the internet and tried to adjust the config to our needs, but I'm sure it's not optimized. We're using 3.3.1 on top of XFS. The qcow images are about 30GB (a couple of 100GB). Can someone please tell what would be the best paramenter for performance to look at? here is volume info: Volume Name: images Type: Replicate Volume ID: Status: Started Number of Bricks: 1 x 4 = 4 Transport-type: tcp Bricks: Brick1: vmhost2:/exports/1 Brick2: vmhost3:/exports/1 Brick3: vmhost5:/exports/1 Brick4: vmhost6:/exports/1 Options Reconfigured: performance.cache-max-file-size: 1GB nfs.disable: on performance.cache-size: 4GB performance.cache-refresh-timeout: 1 performance.write-behind-window-size: 2MB performance.read-ahead: on performance.write-behind: on performance.io-cache: on performance.stat-prefetch: on performance.quick-read: on performance.io-thread-count: 64 performance.flush-behind: on features.quota-timeout: 1800 features.quota: off Thanks in advanced. -------------- next part -------------- An HTML attachment was scrubbed...
