rsync在传输过程中突然无限期地挂起 [英] rsync suddenly hanging indefinitely during transfers

问题描述

在过去的几年中，我一直使用rsync一线将Mac Mini桌面(OSX 10.9、2.5 GHz i5、4 GB RAM)上的重要文件夹备份到FreeNAS盒(0.7.2 Sabanda版本) 5266，Pentium D 2.66 GHz，822MiB RAM [系统报告，我认为其中有1 GB]).我在FreeNAS机器上运行rsync守护程序.最近，这些转让已无限期地暂停.我已经完成了通常的Google-fu，并且无法确定问题的根源或解决方案.

For the past few years, I have been using an rsync one-liner to back up important folders on my Mac Mini desktop (OSX 10.9, 2.5 GHz i5, 4 GB RAM) to a FreeNAS box (0.7.2 Sabanda revision 5266, Pentium D 2.66 GHz, 822MiB RAM [reported by the system, I think there's 1 GB in there]). I am running an rsync daemon on the FreeNAS box. Recently, these transfers have been hanging indefinitely. I have done the usual Google-fu and am unable to identify the source of the problem or a solution.

单线是:

rsync -rvOlt --exclude '.DS_Store'                                  \
      --exclude '.com.apple.timemachine.supported'                  \
      --delete /Volumes/Storage/Music/Albums/ 192.168.1.100::albums

我曾尝试启用-vvv和--progress，但是我无法辨别什么挂起和什么没有挂起.哎呀，如果我重试，同一文件可能会在传输过程中挂在另一个位置，或者根本不挂.空运行(-n)也不总是成功.我唯一获得的成功"是实现超时(--timeout=10)并一遍又一遍地重新运行命令.最终，我一直在前进，但是并不能保证成功，而且步伐是无法接受的.我已经达到一个无法逾越的文件.

I have tried enabling -vvv and --progress, but there is no pattern that I can discern between what hangs and what doesn't. Heck, if I retry, the same file might hang at a different point during the transfer or not at all. A dry run (-n) does not always succeed either. The only "success" I've had is implementing a timeout (--timeout=10) and rerunning the command over and over. Eventually, I creep along, but with no guarantee of success and at a pace that is unacceptable. I've reached a point where I have one file that I can't get past.

Mac Mini通过5 GHz连接到我的路由器. FreeNAS盒通过100兆位端口连接到同一路由器.实际进行传输时，rsync --progress报告为2.5-4 MB/s.根据--progress的说法，挂起实际上就是—据我所知，没有发生任何数据传输.

The Mac Mini is connected to my router via 5 GHz. The FreeNAS box is wired into that same router on a 100 mbit port. When transfers are actually going, rsync --progress reports 2.5-4 MB/s. According to --progress, a hang is literally just that—no data transfer is occurring as far as I can tell.

在诊断和解决方案方面我都需要帮助.

I need help with both the diagnostics and the solution.

推荐答案

我一次又一次遇到相同的问题，如果您删除了-v选项，这似乎有帮助(如果需要该输出，这很烦人) ).

I've been running into the same thing again and again and it seems to help if you drop the -v option (which is annoying if you need that output).
