Hi, I just installed 2 servers with FreeBSD 8.1rc2 and configured block level replication with HAST and fail-over with ucarp. It works like a charm, replication is pretty fast (35MB/s on my one disk system) and fail-over works great. Now I would like to export some ZFS volumes over NFS (for the moment, but CIFS and iSCSI probably later). When I mount a client over the VIP, fail-over works well for directory listing, but as soon as I try to do copy a file and switch node, the copy freeze. I suppose it's because I have to share some kind of temporary directory also over my two server. On Linux, I would probably share /var/lib/nfs also, but on FreeBSD I'm a little bit lost. Is it possible to solve my problem by sharing information over my two NFS servers ? Will I have the same problem (or another one) with CIFS and/or iSCSI export ? Thank you in advance for your answers, and a big bravo for all the developers that bring that kind of stuffs to us. Mickaël
