Abstract. The Cluster Safe File System (CSFS) is a distributed file system that
can provide features such as single name space and remote data mirror. Files in
the file system are scattered on all or some of the nodes in the cluster, and all
nodes in the cluster can access the CSFS file system by mounting it on a local
directory, clients can access the file system via NFS, FTP, Samba, etc. Every
file in the file system has its synchronized mirror on another node, and that is
why we call it SAFE. And in fact we can easily expand it to support more than
one synchronized mirrors.
1 Introduction
High Available clusters are more and more widely used to provide non-stop services,
such as web services, commercial and banking system, etc, in which cases, temporary
failure might cause great loss and catastrophic consequences. And in many case, data
loss is more intolerable than service failure, so it is also very important for a HA
cluster to provide HA for its data. The CSFS is such a cluster file system which
provides a mirror for each file in the file system on another node in the cluster to
prevent from data loss. The CSFS is a filtering file system which is based on other file
systems such as ext3, reiserfs, etc. The CSFS is both safe and single file system..
The CSFS is not designed from scratch. It is based on some existing open source
projects such as FailSafe, PVFS and Intermezzo. It is designed for our cluster system
based on the SGI’s Linux FailSafe.
2 Architecture
The CSFS system is a distributed file system.Its physical arrangement and data
mirroring mechanism are transparent to users.
The architecture of CSFS is made up of five parts (see figure 1, the CMOND is the
cluster monitor daemon which can monitor processes), Linux kernel module
(CSFSKM), Linux virtual device (CSFSDEV), CSFS library (CSFSLIB), file system
service daemon (CSFSD) and file system input/output daemon (CSFSIOD).
Every file in the file system has its synchronized mirror on another node. In
figure 2, the file’ on node2’ is a mirror of the file on node2.
