That's all I really want todo If what you have now works, stick with it.. in general network file systems are very latency sensitive. CIFS might work best *if* your using a WAN optimization appliance, I'm not sure how much support NFS gets from those vendors. iSCSI certainly is the worst, block devices are very intolerant of latency. AFS may be another option though quite a bit more complicated, as far as I know it's a layer on top of an existing file system that is used for things like replication http://www.openafs.org/ I have no experience with it myself. nate _______________________________________________ CentOS mailing list CentOS@centos.org<mailto:CentOS@centos.org> http://lists.centos.org/mailman/listinfo/centos Thanx nate, this is what I wanted to hear :) So, is there any benefit in using NFS over SMB in this case? Can't speak for NFS(3/4), but i can tell you that that smb-protocol combined with high latency is a recepy for disaster. We tried it from europe to the carribean (both sat or fibre) but users spent their time more complaining then working. Needed horrible expensive lan-optimesers at both end So perhaps nfs4 or afs (later is intended for geographically separated machines, afaicr) but certainly not smb! ______________________________________________________________________ Dit bericht kan informatie bevatten die niet voor u is bestemd.
