I was working on a backup script today and doing lots of runs with the --dry-run option to make sure I had things the way I wanted them.
One particular filesystem I was backing up always hung right as it should have been finished. (This happened every time I did a dry run, it was 100% reproducible). Several other filesystems I was backing up had no problems of any kind with the dry run using the same command with different source and dest directories (and exclude lists). Checking all the rsync processes (this was a local file to local file rsync, so everything was on the same system), I found all 3 rsync processes sitting in a select() call, and none of them had any files open, just a couple of sockets and stdout showed up in the /proc/pid/fd directories. I added a --timeout=300 option, and that at least made it exit after 5 minutes. Later, when I removed the --dry-run option and did the real backup, the same filesystem caused no problems at all. No hang, all the backups copied OK, no errors of any kind. I just thought it was weird enough to report, but I'm unlikely to have any time to do any debugging. Just wanted to get it on record in case someone else sees it. This was on a centos 7.0 system, and I updated rsync on it just in case that fixed it, but the problem continued even after the yum update. -- Please use reply-all for most replies to avoid omitting the mailing list.
