Well, I think I partially found out why this is acting strangely. I've tried this on both samba 2.2.5 and 2.2.6rc4. The file handles work a little differently between kernel 2.2 and kernel 2.4.
On kernel 2.2, when you access a directory, you get a single CWD open handle (from LSOF 4.47): COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME smbd 12659 root cwd DIR 8,5 4096 624027 test This CWD is the only handle opened. This handle will stay in use until you click the 'up one folder' button. Just closing the window doesn't seem to help. On Kernel 2.4 you get 3 opened handles. 2 are read handles, while the other is a CWD: (from LSOF 4.63): COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME smbd 14270 root cwd DIR 8,2 4096 131038 disc_test_pc/ smbd 14270 root 22r DIR 8,2 4096 131038 disc_test_pc/ smbd 14270 root 23r DIR 8,2 4096 131038 disc_test_pc/ When you close the window OR click the 'up one folder' button the cwd handle is released. However, the 2 extra read handles are not released. And, every instance of access to that folder generates 2 more extra read handles. This will happen for EVERY folder inside a share, or the share itself. Actually, the CWD handle will disappear by itself if you wait a few minutes, even if the folder is still in use. So, after using a share with lots of folders on kernel 2.4 you see LOTS of open folder handles when you run a lsof -p <smb_pid_of_a_workstation> even if you've closed all windows to everything on that server, or you clicked the heck out of the 'up one folder' button.. Oh, the above test was without mounting anything. That folder had just a single file in it. Soo...is there anyone out there using samba plus rh 8.0/kernel 2.4 plus sharing a cdrom drive where the disc is being changed regularly? Are you having problems unmounting the disc? :) Again, RH 8.0, kernel 2.4.18, x86 Thanks, Jon At 11:03 AM 10/16/2002 -0700, you wrote: >Hey all, > >I've been fighting a samba share/unmount problem for several days now and may >have found a bug in the connect/disconnect code. > >Basically, it seems that while everything claims to free the connection to >the >share, it doesn't actually happen.
