In a Seafile cluster, one common way to share data among the Seafile server instances is to us NFS. You should only share the files objects on NFS. Here we'll provide a tutorial about how and what to share.
How to setup nfs server and client is beyond the scope of this wiki. Here are few references:
- Ubuntu: https://help.ubuntu.com/community/SettingUpNFSHowTo
- CentOS: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-nfs.html
Supposed your seafile server installation directory is /data/haiwen, after you run the setup script there should be a seafile-data directory in it. And supposed you mount the NFS drive on /seafile-nfs, you should follow a few steps:
- Move the
seafile-datafolder to/seafile-nfs:
mv /data/haiwen/seafile-data /seafile-nfs/
- On every node in the cluster, make a symbolic link to the shared seafile-data folder
cd /data/haiwen
ln -s /seafile-nfs/seafile-data /data/haiwen/seafile-data
This way the instances will share the same seafile-data folder. All other config files and log files will remain independent.
