[Gluster-users] Performance question: Replicated with RAID0, or Distributed with RAID5?

2018-06-29 Thread Ernie Dunbar
Hi everyone. I have a question about performance, hoping that perhaps someone has already tested these scenarios so that I don't have to. In order to maximize a Gluster array's performance, which is faster: Gluster servers with 6 SAS disks each set up in a RAID0 configuration, letting Gluster

Hi Raghavendra, We ran the tests (write tests) and I copied the log files for both the server and the client to http://mseas.mit.edu/download/phaley/GlusterUsers/2018/Jun29/ .  Is there any additional trace information you need?  (If so, where should I look for it?) Also the volume

[Gluster-users] Tiering and arbitrated replicated volumes

2018-06-29 Thread D'ALESSANDRO Davide
Hello, I read from Red Hat website that Gluster has this limit: - Tiering is neither compatible with arbitrated replicated volumes, nor with Samba I wonder if this limit still applies to version 3.14 and 4.0 . Indeed I was planning to use tiering with SSD drives, but keeping the 2x3

Hi Raghavendra, Our technician was able to try the manual setting today.  He found that our upper limit for performance.md-cache-timeout was 60 not 600, so he used that value, along with the network.inode-lru-limit=5. The result was another small (~1%) increase in speed.  Does this
