Problem in creating and reading files in CIFS mount in linux

Hello Experts,

I have directory which is mounted to cifs share via /etc/fstab file, the directory has  permission has shown below when it is mounted.

# ll
total 11509
drwxrwxrwx 1 applmgr dba    4096 Apr 29 01:26 HFM_BPC_TRIGGER_FILES

i have user name oracle who is part of dba group.
id oracle
uid=200(oracle) gid=511(oinstall) groups=511(oinstall),512(dba)

we have pl/sql script that is being invoked using oracle id, and that script writes output file to HFM_BPC_TRIGGER_FILES directory. The weird thing is that i can not see the output file when the directory is mounted to cifs share, and when i unmount it i can see the output file.

can someone shed light on why this behaviour ?

my fstab entry

//windows_server/Trigger_BPC/    /oracle/d1/oracle/xxvm/11.5.0/data/outlooksoft/HFM_BPC_TRIGGER_FILES cifs rw,credentials=/opt/int9/.pass,file_mode=0777,dir_mode=0777,uid=212,gid=512   0 0

When the mount is disconnected, where do you see the files?

In the Trigger_BPC folder?
Or in the /oracle/d1/oracle/xxvm/11.5.0/data/outlooksoft/HFM_BPC_TRIGGER_FILES folder?

Look in the server logs on the server (the one with fstab). Are there errors that mention HFM_BPC_TRIGGER_FILES?

Hello,

can you please explain this part in more detail:
The weird thing is that i can not see the output file when the directory is mounted to cifs share, and when i unmount it i can see the output file.

Where do you see the file and when exactly? Do you see it the local directory then the cifs share is unmounted?

Also, you may want to use lsof when the script is running; the following shows you all processes accessing your share at the moment:
lsof | grep HFM_BPC_TRIGGER_FILES

Open in new window


This way you see if your perl script has the file really open.
