Samba issues and debug tools
I've been experimenting with partitioning disks recently (nearly losing my music collection in the process) and I've noticed that when I mount other drives, I lose Samba access completely. This is a bit of a shame.
It turns out that /bin/smbcom crashes if it can't read a file called .smb.ses on any drive listed in /etc/mtab.
To help me discover what's gone wrong, I've built strace (see attachment) with the help of gentoo.
The solution to the problem seems to be to copy .smb.ses from /mnt/HD_a2 to your other drives and edit it.
So, for /mnt/HD_a3 mounted on /dev/sda3, my file contains the following:
Code:
#version = 1.04 [ HDD_b ] comment = path = /mnt/HD_a3 valid users = read only = no guest ok = yes
I can then see the partition as HDD_b in Windows.

You may also mount second partition as a /mnt/HD_a2/otherpartition, then you don't need to mess with samba

Re: Samba issues and debug tools
Agreed, but if you then plug in a USB card reader, for example, smbcom will run, it will fail to find .smb.ses in /mnt/HD_a2/otherpartition, crash and leave an empty smb.conf file (I forgot to mention that bit). You then lose Samba access to everything, not just your new partitions.

Re: Samba issues and debug tools
Sorry to bring back an old topic but this smbcom thing...
I'm using a DNS-323 so things might be slightly different but I'm guessing it works the same.
smbcom on my system is just a symlink to /sys/crfs/samba/smbcom
lrwxr-xr-x 1 root root 22 Feb 8 19:22 smbcom -> /sys/crfs/samba/smbcom
What if you got rid of that symlink and created a script to parse the mount table and if the .smb.ses file doesn't exist, create it. And then of course, call smbcom after the script finishes creating .smb.ses files.
I found the same issue with smbcom on my DNS-323 when I was doing some mount --bind operations. It would segfault when it hit one it didn't like, but it wouldn't corrupt my samba configuration file.
Just a thought.
