Protected snapin unable to be deleted



  • hey folks

    running version 4582 based on the fog icon and had set a snapin to be protected and linked to a second storage group.Now when I check that snapin the general tab and storage group tab respectively are blank.

    So I cannot remove that definition or edit it.

    I can remove the file itself from with the FOG server file system at /opt/fog/snapins.

    I think from memory there is a way to manually edit the database to bypass this but search function on the forum seems limited at best at the moment.

    regards, Kiweegie.



  • @Tom-Elliott Hi Tom

    I meant I manually removed the snapin from /opt/fog/snapins folder on the server, was looking for a way to remove reference to same in the DB/Web GUI.

    It doesnt’ matter now though I’ve just rebuilt Fog having backed up image and snapins etc I need.

    Mark this one as resolved, thanks for your efforts.

    regards Kiweegie.

    What do you mean?



  • @Tom-Elliott I have already manually removed the snapin from the file system I just need a way to bin off the reference to it in the web GUI

  • Senior Developer

    I have not been able to replicate the issue you are describing, but I can assure you now that snapin file (and image file) deletion from a delete object side works properly now.

    I’d recommend taking a look at the entries in the DB and see if recreating them will work better.


  • Senior Developer

    @Kiweegie I believe you may happen to just have a bad snapin.

    Can you actually remove it yourself from the information? It’s looking for a variable that hit should not ever be able to see.



  • @Tom-Elliott Hi Tom, really appreciate the effort you’v put in to resolve this. I can confirm that the Host Export button now works as expected. Everything bar one is now functional as far as I can tell.

    Edit of the snapin i wish to remove/mark as unprotected shows blank page. Log file element below will hopefully help you pinpoint issue.

    Line it refers to reads as

     throw new Exception(sprintf('%s: Failed to connect. Host: %s, Error: %s', get_class($this), $this->get('host'), $error['message']));
    

    cheers, Kiweegie

    Pulled down latest git version and the host element is resolved, thanks. Snapin deletion remains an issue though, is that expected?

    Hopefully all of the errors you presented are now properly fixed. Thanks.


  • Senior Developer

    @Kiweegie I am still aware of the snapins being an issue as well as images and I have fixed the deletion of them on my side and just working out a couple other bugs.

    Additionally the Host Export function is still returning server error. Apache log below.

  • @Tom-Elliott HI Tom

    Pulled down latest git version and the host element is resolved, thanks. Snapin deletion remains an issue though, is that expected?

    regards Kiweegie.


  • Senior Developer

    Found the create new host issue was related to the location plugin.

    I have pushed a fix for this now. Thanks.


  • Senior Developer

    @Kiweegie I’m not seeing any issues with creating a new host on my end. Is there any information in your apache error logs? Is it possible you have the location plugin and I messed something up there?



  • @Tom-Elliott Hi Tom just wanted to add some other issues found since upgrading to latest release (4324).

    Clicking the Create New Host button results in a page which resolves to http://FQDN_of_FOGServer/fog/management/index.php?node=host&sub=add and just states

    “Add new host definition”

    List hosts and edit existing hosts works as expected. Create new User and Create new Group also working so looks like its limited to the Hosts entry.

    Similarly if I try and export Hosts list to csv using Export Hosts button I get a Server 500 error in Chrome, a blank page in Firefox. Presume this is linked to the Snapins issue?

    Happy to test other things, provide logs etc just let me know what you need from me.

    regards Kiweegie.



  • @Tom-Elliott Cheers Tom, appreciate the effort.


  • Senior Developer

    I’ve confirmed the issue, but have not found a fix yet. I don’t consider it overly bearing, but rather a nuisance at this point. I assure you I will get it, but it may take a minute or two.



  • @Tom-Elliott HI Tom

    accessing that page then tailing /var/log/httpd/error.log shows this

    Can grab more if you need it. Accessing the snapin page with Chrome (I use Firefox as preferred browser) shows this error.

    Server error

    500
    ReloadHide details
    The website encountered an error while retrieving http://<fqdn of FOG Server>/fog/management/index.php?node=snapin&sub=edit&id=3. It may be down for maintenance or configured incorrectly.

    Not sure if that helps or not.

    Regards Kiweegie.


  • Senior Developer

    @Kiweegie can you get the blank and then get me some of the trailing Apache error logs.



  • @Tom-Elliott hmmm thats not really improved things :)

    Now on git revision 4324 and all looking hunky dory apart from this one snapin. Now when clicking on the snapin the entire page is blank. Not just the general page and storage group pages being blank (but still showing Snapin Menu on the left and subheadings etc, now I get nothing, nada, rien, zip diddly squat. You get the idea.

    URL goes to <fog IP address>/fog/management/index.php?node=snapin&sub=edit&id=3

    Its only this one snapin and I don’t really care what happens to it - is there a way to nuke it from orbit?


  • Senior Developer

    I say update as I’m fairly sure I default a “primary group/node” for snapins and images if there is not one associated with it.
    This should be fixed in current.
