I earlier this week upgraded from Debian woody to sarge on a machine that does a nightly backup to another machine via a samba share. Since then I have had some issues with accessing that share with I believe are a result of the upgrade. I upgraded the kernel at the same time to 2.4.27-1-686 #1 via apt-get, which might be the related to the problem. Smbfs is version 3.0.6-3 (http://packages.debian.org/testing/otherosfs/smbfs ). I am looking for some advice as to how to proceed with further troubleshooting. Here is how I mount the share in fstab. I should move the user/pass to a credentials file, but one thing at a time (this works): /etc/fstab: //wardrobe/backup /backup smbfs defaults,fmask=644,dmask=755,password=***,user=*** 0 0 Once the share is mounted I am able to list directories, create and modify small files (touch, echo, etc). I don't get any errors and things look like they are working fine. However, when I try to copy a ~200 MB file is when I get into trouble. Error on the command line: aslan:/backup/test# cp wardrobe.tar.gz.1 wardrobe.tar.gz_test123 cp: writing `wardrobe.tar.gz_test123': Input/output error Errors from syslog: Sep 10 07:53:06 aslan kernel: smb_get_length: Invalid NBT packet, code=39 Sep 10 07:53:06 aslan kernel: smb_request: result -5, setting invalid Sep 10 07:53:06 aslan kernel: smb_writepage_sync: failed write, wsize=4096, result=-5 Sep 10 07:53:09 aslan kernel: smb_retry: successful, new pid=28697, generation=2 Sep 10 07:53:09 aslan kernel: smb_get_length: recv error = 5 Sep 10 07:53:09 aslan kernel: smb_request: result -5, setting invalid Sep 10 07:53:32 aslan kernel: smb_retry: successful, new pid=28697, generation=3 Cat /proc/filesystems nodev rootfs nodev bdev nodev proc nodev sockfs nodev tmpfs nodev shm nodev pipefs cramfs nodev ramfs nodev devfs nodev devpts ext3 nodev smbfs Looking through my boot logs, the only error that I can see is the following: Sep 10 11:01:20 aslan modprobe: Note: /etc/modules.conf is more recent than /lib/modules/2.4.27-1-686/modules.dep Sep 10 11:01:21 aslan last message repeated 3 times I have done a pretty complete Google search and a search of the archives and not found anything that has helped. Anyone out there have any suggestions? The machine that I am making the mount from is running the same (up to date) version of Samba. Thanks, Sam
