Just "did it work" tests, copy 20-30GB to server, do md5 on the data pulled back from the server. Didn't hang, performance testing later. 2.6.20-rcX used to copy all files then hang on certain operations that I think used the VFS. 2.6.21-rc1 stalls the NFS transfer itself after several GB. The data was never corrupted. Have you tried copying _ALL_ 190 GB to the server? No, but as noted I was doing 20-30GB, so if "several" is a small number I'm not seeing that behavior. I'm using a Gbit connection if that is not the same as your setup. I have additional testing queued for time available this week. -- bill davidsen <[EMAIL PROTECTED]> CTO TMR Associates, Inc Doing interesting things with small computers since 1979 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
