The Samba-Bugzilla – Bug 4753
copying some binary files on a mount smb gives an input/output error
Last modified: 2009-05-13 16:04:32 UTC
We use a linux server (server A) to copy a lot of files (more than 20000 per day) on another linux server (server B) by a samba mount.
We migrated the old server A, wich was running a redhat 7.2 and now it's a redhat entreprise 4. The server B is running a debian sarge.
We copy these files since 5 years by the same way, we never got an error. Since we are in rh4 with the samba client 3.0.10, generally there are no problems, except on some files: on some files, the copy blocks, and we got an input/output error. We can reproduce the problem with the files we got.
We have the problem with the mounts on w2k server. I changed the mount type smbfs -> cifs, but the problem's still there.
I added an nfs mount to unblock the process, and the copy works without any problems.
We have the same problem to connect on w2k workstations.
Is this still a problem? Is there a testcase to reproduce this problem?
You can turn on cifs debugging
echo 7 > /proc/fs/cifs/cifsFYI
and send that log as soon as you see a problem.
almost certainly resolved now, and no response in a long time.
We made various fixes to the send path which help large file copies
