Kushal Das: Home storage cluster with Fedora and Gluster In a previous post I wrote about the encrypted storage I am using at home. Using Banana Pi, and Fedora. But, for my photos I had to look for something else. I need redundancy. The of the self NAS boxes which can do network and RAID are super costly in my standard. So, I decided to build that at home. The setup is simple that can be done in few hours. I have 2 Banana Pi(s) running Gluster , replicated 2TB hard drives over a local Gigabit network. My old Banana Pi is where I mounted the Gluster volume. First set up the Fedora for Banana Pi(s). I am using the minimal Fedora 23 images. $ sudo fedora-arm-image-installer --image=/home/kdas/Fedora-Minimal-armhfp-23-10-sda.raw.xz --target=Bananapi --media=/dev/mmcblk0 --selinux=ON Due to a bug in the F23 images, I had to remove initial-setup service from the installations. $ rm /run/media/kdas/__/etc/systemd/system/multi-user.target.wants/initial-setup-text.service Then I setup my ssh key on the cards. $ USER=YOURUSERNAME $ sudo mkdir /run/media/$USER/__/root/.ssh/ $ su -c 'cat /home/$USER/.ssh/id_rsa.pub >> /run/media/$USER/__/root/.ssh/authorized_keys' $ sudo chmod -R u=rwX,o=,g= /run/media/$USER/__/root/.ssh/ Installing and enabling ntp # dnf clean all # dnf install ntp # systemctl enable ntpd Setting up the hostname I just set the hostname on the all the 3 systems as gluster01, gluster02, and storage. # hostnamectl set-hostname --static "gluster01" Setting up static IP using networkd I prefer to use Networkd on head less systems. So, I used the same to setup static network on all the systems. # systemctl disable NetworkManager # systemctl disable network # systemctl enable systemd-networkd # systemctl enable systemd-resolved # systemctl start systemd-resolved # systemctl start systemd-networkd # rm -f /etc/resolv.conf # ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf # vi /etc/systemd/network/eth0.network The configuration of the network file is given below. This is much easier for me to maintain than ifcfg files. [Match] Name=eth0 [Network] Address=192.168.1.20/24 Gateway=192.168.1.1 # These are optional but worth mentioning DNS=8.8.8.8 DNS=8.8.4.4 NTP=pool.ntp.org Remember to setup all 3 systems in the similar way. Replace the IP/Gateway address as required. I also updated the /etc/hosts file in all the 3 systems so that they can talk to each other using hostname than IP addresses. Setting up the new hard drives First we create a new partition, and then format it as ext4. I also added the corresponding address in the fstab file so that it gets mounted automatically on /mnt . # fdisk -c -u /dev/sda # mkfs.ext4 /dev/sda1 # vim /etc/fstab Setting up Gluster on the systems Next big step is about setting up Gluster on both the gluster01 and on gluster02 . # dnf install glusterfs-server.armv7hl -y # mkdir -p /mnt/brick/glusv0 # systemctl start glusterd Next I had to enable the required ports in the firewalld. For now I have added eth0 on public zone. # firewall-cmd --zone=public --add-interface=eth0 # firewall-cmd --zone=public --add-service=glusterfs Remember to run the above commands on the both the Gluster systems. Now from gluster01 I enabled a peer. Finally we create the volume, and start it. # gluster peer probe gluster02 # gluster peer status # gluster volume create glusv0 replica 2 gluster01:/mnt/brick/glusv0 gluster02:/mnt/brick/glusv0 # gluster volume start glusv0 # gluster volume info Mount the gluster volume on the third box. # dnf install glusterfs-fuse -y # mount -t glusterfs gluster01:/glusv0 /gluster -o backupvolfile-server=gluster02 # chown USERNAME -R /gluster/ Now you can use the mounted volume in any way you want. I also had a problem in keeping the systems properly. So, I used an old plastic rack to host the whole solution. Less than $5 in cost :) http://ift.tt/1OgEdyb
