Thanks Roland. I appreciate your guidance. Thanks, Phil
this is a linux kernel or hardware issue, please update (if not yet done) your system to the latest patches, especially the kernel package. if that does not help, jump onto these bugreports or open a new one for your distro. (kernel.org bugtracker is typically not the best choice for normal end-users) https://bugzilla.kernel.org/show_bug.cgi?id=12118 https://bugzilla.novell.com/show_bug.cgi?id=579932 regards roland *Gesendet:* Freitag, 07.

I've tried to keep it as simple as possible considering... Various remote hosts(running rsync daemon) -> HOST A(rsync pull / backup-dir=NFS host) ----> HOST B(NFS export for backup-dir) ----> When HOST A is done pulling the data from the various hosts a second script starts and rsync's(push) to HOST C. Every other time HOST C grabs a fresh copy directly from the remote hosts. Of course, this part is never automatically achieved since I'm never around to key "waking" the system from the console. So every time I walk by I hit a key and it keeps going. > > please provide the command which works and which not. hangs with: -avS --exclude-from=exclude.rsync --delete --backup --backup-dir=/path/to/nfs on HOST B/date +today's date does not hang with: -avS --exclude-from=exclude.rsync --delete --backup --backup-dir=/path/to/local/date +today's date fs on HOST A > > > so - resuming from hang is all about keypress?

Question: I'm running this in cron as root. Although root can rw to the NFS share while I'm in the console, is it somehow possible I'm encountering a permissions issue and just not seeing a "permission denied" anywhere?
