--- Comment #8 from Eric Chaput <sa...@ftd.idms.com> 2014-04-06 13:47:15 UTC --- I struggled with the same problem trying to rsync a particular large VM file. Even though your random data trick didn't help it got me thinking about the issue and I thought couldn't we just increase the blocksize of the delta xfer algorithm until it chunks it out in few enough pieces? It turns out that you cannot increase it to more than 128k for protocol version 30, which rsync 3 uses. Thankfully you can specify which protocol version to use. I tried 1MB, same problem, cpu hangs on sender at some point, then tried 10MB and that worked for me (40GB VM img which probably contains 50% nuls). Here are the command parameters I used: --block-size=10485760 --protocol=29 I'm using --inplace too in case that matters, and stock rsync 3.0.7 from debian squeeze on both ends -- Configure bugmail: https://bugzilla.samba.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. -- Please use reply-all for most replies to avoid omitting the mailing list.
