R/W DASD shared among zLinux images...

Fri Oct 28 13:07:01 UTC 2005

Is there a properly intelligent filesystem and driver that can handle a read-write filesystem across multiple zLinux images?

We're trying to install the set of Tivoli products, using zLinux as the server for many of the pieces, and the folks doing the install have come to a piece that says it will run on zLinux, but requires R/W access to a specific directory from all servers participating in the cluster. The Tivoli people want to do the HA install, and so would want / need this directory on a filesystem that can be R/W to multiple zLinux guests.

I am unaware of any viable solution. NFS doesn't cut it, because the NFS server could go down. Are there any alternatives?
