Installation
RozoFS is mainly tested on Debian wheezy. The Debian packages should build and work smoothly on Debian and derived distributions (including Ubuntu). Packaging for other distributions is welcome.
cd /path/to/your/sources
git clone https://github.com/rozofs/rozofs.git
Install the required packages:
cd rozofs
sudo apt-get install build-essential git-buildpackage
dpkg-checkbuilddeps
#... and install the missing build dependencies
Build:
git-buildpackage
Use dpkg or apt-get (if you have setup a repository).
Install :
- rozofs-exportd on the exportd node (or several nodes if your are using Corosync+Pacemaked)
- rozofs-storaged on the storaged nodes
- rozofs-rozofsmount on the client nodes
- rozofs-manager-agent and rozofs-manager-cli on all nodes (optionnal)
NB: a node can have exportd+storaged+rozofsmount
Edit /etc/default/rozofs-manager-agent and change AGENTS to match locally installed daemons. Example:
AGENTS="exportd storaged rozofsmount"
Then restart:
service rozofs-manager-agent restart
On all storaged nodes, create a raw storage filesystem. Example:
mkfs.ext4 /dev/vg01/storage
mkdir -p /srv/rozofs/storage
mount -o noatime /dev/vg01/storage /srv/rozofs/exports
On all storaged nodes, start storaged:
service rozofs-storaged start
On the exportd node, create the raw export filesystem. Example on a Pacemaker setup (ext4 parameters are tuned with the expected data):
mkfs.ext4 -b 1024 -I 256 -i 4096 /dev/drbd2
mkdir -p /srv/rozofs/exports
mount -o noatime /dev/drbd3 /srv/rozofs/exports
On the exportd node, start exportd:
service rozofs-exportd start
Read export.conf(5) man page, and eventually change layout. Example:
rozo layout -E <ip_of_exportd> 1
Declare a volume using all storaged nodes:
rozo expand -E <ip_of_exportd> --vid 1 <ip_of_storaged1> <ip_of_storaged2> <ip_of_storaged3> ...
Declare an export (FS) using all storaged nodes (using volume created above with vid=1):
rozo export -E <ip_of_exportd> 1
Create mountpoint, add to fstab and mount on all (FS) using all storaged nodes (using volume created above with vid=1):
rozo mount -E <ip_of_exportd> -e 1
Test :
df -t fuse.rozofs
touch /mnt/rozofs@<ip_of_exportd>/export_1/test
ls -l /mnt/rozofs@<ip_of_exportd>/export_1
Using the basic configuration, the exportd daemon is not to protected against fault-tolerance. This can be done with Corosync and Pacemaker.
