I’m not sure your list is quite correct. It depends on what you mean by a file system. If you mean a file system that is mountable in an operating system and usable by any application that reads and writes files using POSIX calls, then GridFS doesn’t really qualify. It is just how MongoDB stores … Read more
I like GlusterFS. Actually, I adore GlusterFS. As long as you can give it some dedicated bandwidth everything’s fine. One of the best things about GlusterFS is using it with NFS. One of the surprising things I’ve been working with lately is NFS on Windows 7 and 2k8R2. Here’s what I’d do. Set up 2 … Read more
We recently started researching GlusterFS for our own usage so this question was interesting to me. Gluster uses what are called ‘translators’ on the FUSE client to handle how you store data. There are several types of translators which are outlined here: http://www.gluster.com/community/documentation/index.php/GlusterFS_Translators_v1.3 The one you are asking about specifically is called the Automatic File … Read more

But make sure to restrict which clients can mount the volumes and encrypt the connections. There was no questions asked. I did nothing to tell server2 … Read more

I set this up on Ubuntu and briefly here are the steps: Install Ubuntu Install and configure glusterfs Install mysql-server Configure /etc/mysql/my.cnf to set datadir … Read more
This has been a request to the GlusterFS developers for a while now and there is nothing out-of-the-box solution you can use. However, with a few scripts it’s not impossible. Pretty much entire Gluster system is managed by a single gluster command and with a few options, you can write yourself health monitoring scripts. See … Read more
You should start the volume with state: started: – name: Configure Gluster volume. gluster_volume: state: started name: “{{ gluster.brick_name }}” brick: “{{ gluster.brick_dir }}” replicas: 2 cluster: “{{ groups.glusterssl | join(‘,’) }}” host: “{{ inventory_hostname }}” force: yes become: true become_user: root become_method: sudo run_once: true ignore_errors: true
I hope this is gonna help a little. I tried to not let it turn into a full wall of text. 🙂 3Par/Isilon If you can and will dedicate a fixed amount of man-hours for someone who takes the SAN admin role and wanna enjoy a painless life with night-sleep instead of night-work then this … Read more
Why yes, it is possible to build an active/passive ZFS-based cluster using shared DAS and multipath SAS. Details at: https://github.com/ewwhite/zfs-ha/wiki The key to this high-availability storage design is a shared SAS-attached storage enclosure, or JBOD. While it’s not shared-nothing, this can be a useful way of bringing higher availability to a storage setup that can … Read more
You can analyze systemd boot sequence by following command. View the output file by using a SVG supporting web browser. systemd-analyze plot > test.svg That plotting will provide you last boot’s timing statistics, which will provide you more clarified point of view to problem. I solved my NFS mounting problem by adding mount commands in … Read more
