GlusterFS
GlusterFS is a distributed filesystem. It has built in redundancy, so it is possible to run two servers which automatically replicate files between the servers. If one server goes down, the other just takes over. Once it comes up again, files are automatically replicated. Here we will use GlusterFS as a redundant network mounted file storage.
For the sport of it, we will configure 4 GlusterFS servers.
Network
The GlusterFS servers will have fixed IP-addresses. That is configured in the DHCP servers list of statically assigned IP-adresses by using the Domains MAC address.
- 192.168.1.40 gluster01
- 192.168.1.41 gluster02
- 192.168.1.42 gluster03
- 192.168.1.43 gluster04
Disk
Add hardware
Domain Editing We will add an additional disk to the system. This disk will be used for file storage.
in the guest
Configure disk
Partition
Create one large partition on vdb with partition type 8e (linux lvm).
LVM
Set up a new physical volume and volume group
pvcreate /dev/vdb1 vgcreate vg2 /dev/vdb1
LVM Volume
lvcreate --size 4G --name gluster_www vg2
Mountpoint
Create the mountpoint.
mkdir /srv/www
Format
Format the volume.
mkfs.btrfs /dev/vg2/gluster_www
fstab
Add the volumes to /etc/fstab.
/dev/vg2/gluster_www /srv/www btrfs defaults 0 0
Software
apt-get install glusterfs-server
from gluster01 connect with the other gluster servers
gluster peer probe gluster02 gluster peer probe gluster03 gluster peer probe gluster04
check server status
gluster peer status Number of Peers: 3 Hostname: gluster02 Uuid: 031573c2-3b1f-4946-bd78-421563249db6 State: Peer in Cluster (Connected) Hostname: gluster03 Uuid: ff5cec1c-6d7f-4db7-8676-08deff06b4d0 State: Peer in Cluster (Connected) Hostname: gluster04 Uuid: 65fc398a-52e9-4292-9bbb-884becfbf5d6 State: Peer in Cluster (Connected)
create the gluster volume. the force option is needed because we are creating the volume on a mountpoint.
