Bug 82357 – processes freeze suddenly when transfering large files to cifs shares on a win2k3 server

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Timo 2005-02-17 07:46:07 UTC]

I tried to cp a big file (1G) from my local machine to a cifs share that I had mounted from a win2k3 server. Suddenly some processes began to freeze. I could not kill them any of them, kill -KILL as root didn't work. After all only powering off the machine (not a clean shutdown) helped. This is very poor :(

Please test 2.6.11

[Comment 3 Timo 2005-03-17 05:54:41 UTC]

Hi,

I tried gentoo-dev-sources-2.6.11-r3 and it seems like it works with that kernel. Although I cannot test it under the same conditions as before. X was running etc and this time I wasn't able to compile nvidia-kernel and nvidia-glx modules for the new kernel. However I made three nullfiles, 1 GB , 2 GB and 4 GB of size and cp'ed them to the cifs share. Everything went ok except that it took very long especially the 4G one. But I think that's ok.

Now only 2.6.11-gentoo-r3 has to become stable :)

Regards,

Timo

Marking fixed as that is happening soon

[Comment 6 fctk86 2005-07-24 08:28:41 UTC]

i tried kernel gentoo-sources-2.6.11-r4 and uploads with cifs filesystem work!
so it's for sure a kernel bug.

however, i tried to measure speed transfers to compare smbfs and cifs, and i
discovered cifs is much slower then smbfs. the test file was 318MB:
smbfs | up: 3' 32"; down: 23" | up: 1,5MB/s; down: 13,8MB/s
cifs | up: 7' 52"; down 1' 27" | up: 0,7MB/s; down: 3,6MB/s

what could it be?

[Comment 7 fctk86 2005-07-25 11:10:36 UTC]

i fixed my problem... the reason was the absence of a non-null username option!
anyway, cifs is still slower then smbfs...
