[gentoo-user] transfer large files via samba cause system freeze

[Qiangning Hong]

I tried to transfer a large file (~300MB) to a windows machine from my
gentoo laptop:

# mount -t cifs //winbox/movies /mnt/samba -o iocharset=utf8,umask=0000
# exit
$ cp largefile.avi /mnt/samba

The transfer starts and eats 100% of my CPU. However, after transfered
~40MB of data, my linux system freezed: mouse point doesn't move,
keyboad doesn't response, even Ctrl-Alt-Del has no effects. The only
thing I can do is hard-reset my laptop.

If I share this file via samba server and use windows explorer on the
winbox to retrieve it, it works.

It seems something wrong with the samba client?

What if you just try
mount -o username=xxx //winbox/movies /mnt/samba ?

Does this resolve to a smb type mount (instead of CIFS)? Does it work
better? Kernel options for SMB / CIFS ?

Isn't CIFS considered as a better SMBFS?

My winbox is a Chinese version windows, use smbfs will cause the
filename containing Chinese characters messed up.  When use cifs with -o
iocharset=utf8, these characters are resolved correctly.

What do you mean of "Kernal options for SMB / CIFS"?  I just build them
as modules.

It's been said. Still - do you have both SMBFS and CIFS support built
into your kernel, or just CIFS? If the later is true I would include
SMBFS as well and try the same thing with good old SMB as well (you may
use both simultanously anyway).

Interessting details missing: your kernel and windoze version?

I add smbfs support in my kernel and tried (after change the filename to
an English-only one).  It works.

However, as my previous mail said, using smbfs doesn't address my
problem.  I have plenty (~100) large files to transfer, and maybe you've
guessed, they are movie files, with Chinese movie title in the
filenames.  And the movies directories on my winbox have also Chinese
characters.  If I stick in the smbfs solution, I'll have to do too many
manual filename change things.  So, I still prefer to find out what's
wrong with my cifs and fix it.

Can't you also use the iocharset=utf8 and codepage=utf8?

something like:
mount -t smbfs -o user=<user>,iocharset=utf8,codepage=utf8 \\server\path 
/mnt/samba

This doesn't work?

What version samba and do you have "use sendfile = no" in the server smb.conf 
file?

It doesn't work. There are "?"s in the filenames.

samba 3.0.14a-r2.

I don't know how to set options in the windows box.  But in my gentoo
laptop, there is no "sendfile" line in /etc/samba/smb.conf.

That's actually a good thing.... I take it you're doing this in a
terminal? Which one? Was it compiled with UTF8 support?What font is the
terminal using for display? A "?" replacing characters tends to mean (in
font-speak) that the character is 'known', but no actual character
exists to render under the selected font, or font encoding. So you kinda
get a"?" literally because the display doesn't know what to show there,
if you see what I'm getting at.

Are you able to actually use any of the files properly, even if the
filenames are not displayed correctly? Or are you unable to try that,
because you just can't read any of the filenames?

If your Winbox is Chinese, does your terminal, and the display font
chosen for the terminal support Chinese characters?

I've gotta tell you, getting UTF8 and font encoding properly set up so
that 'special characters' appear correctly across programs and terms can
be a pain in the butt, and I'm only needing it for another Latin-based
language, not any of the Asian or Cyrillic languages that use a
completely different character set. But it's well worth doing, because
it's more of a pain to not be able to read filenames or messages because
of these stupid '?'s or other 'placeholder' characters that must be used
in place of the correct ones when the system is not set up to support
the correct ones.

My gentoo system's locale is set to en_US.UTF8 and my
xfce-extra/terminal is fully support UTF-8 encoding.  As my previous
post says, I can see the Chinese filenames using CIFS with the following
command switches:

# mount -t cifs //winbox/movies /mnt/samba -o iocharset=utf8

But if I mount the path using smbfs, even specified
iocharset=utf8,codepage=utf8, the filename is shown incorrectly.  I
don't think it's because of my terminal encoding setting.
