List-Post: List-Help: List-Subscribe: , List-Archive: Hi, I had this neat idea that NFS failover of read-only filesystems can be achieved using wackamole (floating IP adresses providing very simple HA). This did not work with NFS 3 because the filehandles are different on the primary and the secondary servers, so I was getting a "stale NFS filehandle" error after the failover. I tried this using NFS 4 nfs-utils-1.0.6-52 from FC3 updates. However, it still failed with the following error: ls: reading directory a: Input/output error and this in the error log on the client: kernel: RPC: garbage, exit EIO Is this a bug or a feature?
