Shared file storage

[stilmark]

What is the recommended shared file storage solution for a remote server. The documentation refers to:


External NAS + NFS
GlusterFS
iSCSI+mdadm+reiserfs+NFS


Since External NAS + NFS is not an option I have been looking at GlusterFS, but installation tutorials are pretty scarce.

I will be installing ISPman Cluster on a Debian 5 64 bit LAMP OS.

Suggestions or pointers?

Upon further reading it seems that NFS is actually the easiest to setup on Debian, a tutorial can be found here:

http://www.howtoforge.com/nfs-server-and-client-debian-etch

However, which access restrictions should be imposed in exports?

# /etc/exports: the access control list for filesystems which may be exported

/storage 192.168.0.101(rw,sync)

or

/storage rw,sync

or should the restrictions include all the IPs in the cluster?

Does anyone have experience with a NFS setup? What's the best way to configure it?

Please note, that GlusterFS has a long response time in small files. For example, our Wordpress tests have shown that the time for opening web-pages increase by 3-4 times.

The easiest means is to allow access to storage only for the Cluster internal network and deny connection from port higher than 1024. You can do it here /storage 192.168.0.0/24(rw,sync,secure). Otherwise, you will have to customize authorization via Kerberos, which is much more difficult.
