Windows Server 2003 shares sometimes become unavailable

trafikpolisen · 05-18-2013, 06:39 PM

I have a Windows Server 2003 machine which i store most of my files on. Occasionally it becomes unavailable and the shares shows up as zero byte files created 1970-01-01 01:00. If i try to mount a share (mount -t cifs) I get a permission denied error. All of a sudden it works again or if I don't have the patience to wait it out and do a reboot or log out/in again it works right away. 95% of the time everything works flawlessly, but every once in a while this happens. I have checked the logs on the server without finding anything explaining this. Any ideas?
Btw, how do you generally mount Windows shares out there? I use a script that runs with root permissions at every login (/etc/mdm/PostLogin/default).

just use mount -t cifs with appropriate arguments to mount em.

typically what you are describing is one of two things.

1. LAN connection issues. if the LAN has a hickup then the connection can be dropped. If that is the case depending on how the share is mounted this can cause Linux to get confused.

2. win2k3 is just old and could be dropping the connection. heck it drops connections across a native network let along a mixed environment.

my money is on #2.

i personally use autofs still to mount my cifs points. here is my win7 mounted to my CentOS 6.x box:

Code:

[user@centos ~]$ cat /etc/auto.master
/mnt/win7	/etc/auto.win7	--timeout=600	--ghost

[user@centos ~]$ cat /etc/auto.win7 
win7	-fstype=cifs,rw,noperm,username=XXXXXXXX,password=XXXXXXXX	://win7/g

This works great for me. when ever the user/system wants access to the mount point autofs mounts the share and it is seamless as far as the user(s) know.

Maybe a dhcp lease issue?
