IOError: [Errno 13] Permission denied [moving to NAS]

[phillipston]

I'm having a problem with my NAS. Here is a few lines of my SABNzbd error log:

Traceback (most recent call last):
File "/usr/share/sabnzbdplus/sabnzbd/misc.py", line 818, in move_to_path
shutil.copyfile(path, new_path)
File "/usr/lib/python2.7/shutil.py", line 83, in copyfile
with open(dst, 'wb') as fdst:
IOError: [Errno 13] Permission denied:

This happens on absolutely every file I try to download. The failure occurs when moving from my temporary download folder (on the local host) to my completed download folder. My completed download folder resides on the NAS. Note that I used to run OpenElec 2.0 and everything worked fine with SABnzbdplus (an older version I'm sure) and my same Synology NAS. When I upgraded to XBMCbuntu, I could only download to my local server, a Zotac Mag. Whenever I change the completed download directory to my Synology NAS, I get the above error.

Here's my basic info:
SAB Version: 0.7.3
OS: Ubuntu, Xbmcbuntu, Ubuntu 12.10, Xbmc frodo
Install-type: linux repository
Skin Plush
Firewall Software: iptables not configured
Are you using IPV6? No
Is the issue reproducible? yes

It is interesting to note that on my NAS the log states that the user made a directory and renamed it (_FAILED...) and the user account was guest. I do not set my SAB user to guest. Don't know what that's about, but anyway, I have checked all of my user privileges for the completed download directory including guest and they all are set to read and write on the NAS.

I can move files from my Windows XP pc to the NAS, using Windows Explorer and WinSCP.

I think you know the answer.
SABnzbd does not have permission to write to the "complete" folder.
Try to get ssh access to the NAS and check access rights.

[sander]

I would say it is a rights problem. It might be on a subdirectory.

On the XBMCbuntu: what's the output of:

Code: Select all

grep "/" ~/.sabnzbd/sabnzbd.ini | grep dir
df -h
mount

[phillipston]

Sorry, didn't see this thread. I figured it was some kind of permissions thing, but just can't find out where the problem is.

Here is what I have for the requested output:

rickhtpc@Rick-HTPC:~$ grep "/" ~/.sabnzbd/sabnzbd.ini | grep dir
download_dir = Downloads/incomplete
complete_dir = /home/rickhtpc/Movies
script_dir = /home/rickhtpc/.sickbeard/autoProcessTV

[phillipston]

I also checked access rights on the NAS completed directory and it's 0777.

[sander]

What's the output of:

Code: Select all

ls -al /home/rickhtpc/Movies
cd /home/rickhtpc/Movies
touch hello.txt

[phillipston]

Requested output is:

ls –al /home/rickhtpc/Movies
drwxr-xr-x 2 1025 users 0 Dec 15 20:42 Its a Wonderful Life
.
.
.
This is a very long list of movies. Above is a typical entry.

rickhtpc@Rick-HTPC:~$ cd /home/rickhtpc/Movies
rickhtpc@Rick-HTPC:~/Movies$ touch hello.txt
rickhtpc@Rick-HTPC:~/Movies$

[sander]

PS:

What's the output of:

ls -al /home/rickhtpc/Movies/hello.txt

[phillipston]

rickhtpc@Rick-HTPC:~/Movies$ ls -al /home/rickhtpc/Movies/hello.txt
-rw-rw-r-- 1 1025 users 0 Mar 17 17:59 /home/rickhtpc/Movies/hello.txt

Are you running sabnzbd from the commandline, or as a service / daemon. If as a service, under which account?

Furthermore, I only have one advice: check the NAS rights. It's not a SABnzbd thing. Proof: set the Complete folder to your local harddisk, and start downloading.

[phillipston]

OK, thanks. It is not a SABnzbd thing as you say. I have set the NAS rights - it is something else. I run it as a daemon and set the USER in etc/default/sabnzbdplus to rickhtpc, which has read/write privileges on the NAS (however, the NAS only seems to be seeing 'guest' which also has read/write access). I thought it might be a Python related thing. It's just so weird, nothing has changed on my NAS since I upgraded to XBMCbuntu.

I will figure this out!

[sander]

I thought it might be a Python related thing.

Interesting hypothesis.

Did you look at sabnzbd/misc.py around line 816? The problems occurs in the line "shutil.copyfile(path, new_path)".
Have you set SABnzbd's logging to debug? With debug level, you should grep for "Moving" in sabnzbd.log, for example:

Code: Select all

2013-02-27 19:02:37,529::DEBUG::[misc:810] Moving. Old path:/home/sander/Downloads/incomplete/blablalbla/720p.hdtv.x264-knifesharp.nfo new path:/home/sander/Downloads/SABdownloads/_UNPACK_blablala01.720p.hdtv.x264-knifesharp.nfo overwrite?:0

Is there anything special in that line? Strange names / locations? Can you paste it here?

If the line looks OK, you can mimic the "shutil.copyfile(path, new_path)" in a python shell. Here is a two-liner that generates the same error message because I want to write to a location for which I haven't got the rights:

        try:
            # First try cheap rename
            renamer(path, new_path)

            try:

                ok = False
    return ok, new_path

[phillipston]

So, in the SABnzbd log file we have:
2013-03-18 20:40:26,863::ERROR::[misc:822] Failed moving /home/rickhtpc/Downloads/incomplete/True_Grit.2010.BluRay.AC3-NoGroup/rsg-truegrit-xvid.r53 to /home/rickhtpc/Movies/_UNPACK_True_Grit 2010 BluRay AC3-NoGroup/rsg-truegrit-xvid.r53

There is nothing unusual there.

Then when I duplicate the code that you showed to duplicate hte IOError I get the following:

>>> shutil.copyfile("hallo.txt", "/user/bin/magiet")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/shutil.py", line 82, in copyfile
with open(src, 'rb') as fsrc:
IOError: [Errno 2] No such file or directory: 'hallo.txt'
>>>

It is interesting to note that my open call uses 'rb' whereas yours used 'wb'. Can that be the difference?

No, it's not:

Code: Select all

>>> shutil.copyfile("nothere.txt", "/user/bin/notallowed")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/shutil.py", line 82, in copyfile

>>> import shutil
>>> shutil.copyfile(".asoundrc", "Movies/.asoundrc")

The above worked just fine, proving I can write to the mounted directory "Movies" from the local host. Just not with SABnzbd.
