I just tried the workaround of manually setting the MTU size. Ubuntu 13.04 64 bit (up to date; no PPA used).
My test consist in copying my photo archive (average file size 1,5 MB) from a samba share. With MTU left on "Automatic", the copy hangs sometimes after a few tens of files, other times after a few hundred files. Same thing using either WiFi or wired (Ethernet). I only tried changing MTU size with WiFi. MTU 700 - nautilus hangs during copy from a samba share MTU 1000 - nautilus hangs during copy from a samba share MTU 1500 - first test was promising. 1.220 files copied without problems. Then I tried with 16.739 files. Copy hanged after only 80 files. End of test. Test result: manually setting the MTU size workaround is not a workaround in my case. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1075923 Title: nautilus hangs copying large directories from a samba share Status in “gvfs” package in Ubuntu: Confirmed Bug description: I have a large directory, almost 50Gb and 45.000 files shared by samba on ubuntu 12.04.1 LTS server. I used to copy the whole directory regularly on my desktop, and execute a backup with deja dup on that. I did also often backup directly from the samba share. After upgrading my client to 12.10, copying the directory hangs randomly, sometimes after having copied just 1 Gb, others having almost completed the whole transfer. It just hangs, without any crash. I noted the also Deja -dup shows the same behaviour, now it's impossible to complete a backup from the share, it just hangs. It seems to me that a bug in the samba client might be the cause of these issues, since neither nautilus nor Deja-dup have problems with local large directories. my system: Ubuntu 12.10 AMD64 nautilus: 1:3.5.90.really.3.4.2-0ubuntu4 deja-dup: deja-dup 24.0-0ubuntu1 smbclient 2:3.6.6-3ubuntu5 samba-common: 2:3.6.6-3ubuntu5 samba-common-bin: 2:3.6.6-3ubuntu5 ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: nautilus 1:3.5.90.really.3.4.2-0ubuntu4 ProcVersionSignature: Ubuntu 3.5.0-18.29-generic 3.5.7 Uname: Linux 3.5.0-18-generic x86_64 ApportVersion: 2.6.1-0ubuntu6 Architecture: amd64 Date: Wed Nov 7 12:05:58 2012 GsettingsChanges: b'org.gnome.nautilus.window-state' b'geometry' b"'825x550+853+471'" InstallationDate: Installed on 2012-10-22 (16 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) MarkForUpload: True SourcePackage: nautilus UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1075923/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
