NIS and automounted home directories

Nick -

You need to serve out your home directories using some sort of shared storage and NFS clustering.  Don't confuse NIS (Network Information Server) and NFS (Network File System); NIS is only providing the authenication information (username, password, path to home directory, etc).  The actual home directory (data) is being exported by your NFS server.

In a minimal configuration, you would have two systems and three disks.  Each system would have a single disk for its operating system.  The third disk would be connected to both systems; this disk would be used for data like your home directories. Additional software would be installed on both nodes that monitored the health of the cluster and determined which system was acting as the master.  I've used SUN's SunCluster product, but have not used any of the Linux clustering options.

Folks,

Im setting up NIS, here's the picture.

2 NIS servers, NIS1 and NIS2.

NIS1 exports the home dirs.

NIS1 goes down so clients use NIS2 for authentication. Now the users home dirs are gone.

What do you folks do to keep home dirs intact when the NIS server exporting them goes down ?

It's possible we could replicate the exported directories to NIS2 but that really would be a major hassle, some of our developers home directories are huge.

Anyone got any recommendations ?

Cheers,
Nick .
