Plagued by name to sid deadlock errors?

[jpaetzel]

I added a tool to 9.3 this weekend that will help resolve most cases of this. By popular request I backported it to 9.2.1.9. If you're running an older version of 9.2.1.x you'll have to update to 9.2.1.9 before running the tool.

Code:

mountrw /
fetch "http://download.freenas.org/errata/fixsid.py" -o /usr/local/bin/fixsid.py
chmod 755 /usr/local/bin/fixsid.py
mount -ur /
rehash
fixsid.py

I keep getting

Code:

[root@freenas /usr/local/bin]# fetch "http://download.freenas.org/errata/fixsid.
py" -o /usr/local/bin/fixsid.py

fetch: -o: No such file or directory

I think there was a typo in the first post, it should be 'mount -rw /'

 

[diedrichg]

Oh! Yup! I see that now, duh!

I keep getting the following message:

Code:

[root@DENHAM] ~# fixsid.py
Multiple SIDs detected, aborting without making changes.

 

[diedrichg]

I'm still getting the error in post #2.

Hi all, am getting similar errors:

[root@Medusa ~]# mount -rw /
[root@Medusa ~]# fetch "http://download.freenas.org/errata/fixsid.py" -o /usr/local/bin/fixsid.py
fixsid.py 100% of 2312 B 21 MBps 00m00s
fetch: -o: No such file or directory
fetch: /usr/local/bin/fixsid.py: No such file or directory
[root@Medusa ~]# chmod 755 /usr/local/bin/fixsid.py
chmod: /usr/local/bin/fixsid.py: No such file or directory
[root@Medusa ~]#

Any suggestions please?

 

[toadman]

If the wget completes the file is in / (or wherever you were when you executed the wget). So just move the file to /usr/local/bin/fixsid.py. i.e. do:

Code:

mv ./fixsid.py /usr/local/bin/fixsid.py

Then do the chmod on that file as indicated.

BTW the path didn't update for me, so I just did a cd into /usr/local/bin and executed ./fixsid.py

I keep getting the following message:

Code:

[root@DENHAM] ~# fixsid.py
Multiple SIDs detected, aborting without making changes.

i'm getting the same on 9.3 beta

 

[ashori]

Could I just cd to /usr/local/bin/ and do the fetch there?

 

[toadman]

I would think so, yes.

 

[ashori]

Did the above, seems to have worked. Haven't seen any more error messages in the console.

I noticed the rehash command didn't work during the fix though..

<edit>
Whoops looks like it didnt work after all... maybe the rehash was an important step :0?

Hmm, this might be a different issue, after scrolling up the log I see the original error is different.

I keep getting the following message:

Code:

[root@DENHAM] ~# fixsid.py
Multiple SIDs detected, aborting without making changes.

Also getting this on 9.3. Anyone know how to fix this?

 

[diedrichg]

can't get rehash to work either

 

[hervon]

I keep getting the following message:

Code:

Same thing for me with 9.3 Stable. Any way to correct this issue ?

 

[Josh Johnson]

I have 9.3 Stable and I fixed mine with the following changes
-My / was already mounted so no need for 1
-I did 4 but then when i ran script i got trying to write to read only database errors
-'rehash' command didnt exist for me so i googled that hash -r is a replacement and it ran

Original

1. mountrw /
2. fetch "http://download.freenas.org/errata/fixsid.py" -o /usr/local/bin/fixsid.py
3. chmod 755 /usr/local/bin/fixsid.py
4. mount -ur /
5. rehash
6. fixsid.py

Mine

1. fetch "http://download.freenas.org/errata/fixsid.py" -o /usr/local/bin/fixsid.py
2. chmod 755 /usr/local/bin/fixsid.py
3. mount -urw /
4. hash -r
5. fixsid.py
6. Run the commands the script says to after completion or reboot

I havent gotten another sid error in the last ten minutes since running

 

[diedrichg]

Thank you. I'll give this a go later.

I'm also having deadlock errors (FreeNAS-9.3-STABLE-201501090144) so could this fix be included officially?

winbindd[2450]: sam_rids_to_names: possible deadlock - trying to lookup SID....

 

[Josh Johnson]

Like they say every where else the sid deadlock errors could be multiple things, they can't include a fix for it. Take snapshots and try the different fixes until one works for you.

On my system (9.3 stable), I'm still getting this message. Specifically, I get it when trying to add certain users/groups to files and directories through the windows security dialog on datashares shared out via CIFS with windows permissions. The error occurs when I attempt to add users/groups that exist in freenas, but they fail to be found in the windows dialog and this error appears in the console.

I am going to attempt the instructions above and see if this fixes the issue.

---------

Edit: Script did not run:

"Multiple SIDs detected, aborting without making changes."

Unfortunately, I cannot seem to add certain users/groups to files/directories in windows using window security dialog at this point. Some recently created groups work just fine, but other, older groups are not found by windows and cause this error in the console.
