I am very happy that this is resolved now.  Apologies again for the mistake that caused it.  Closing the ticket.

Thank you for your help and detailed explanation.

The issue seems to be fixed since your reply on Friday, I checked some sample reports and did not find any problems.

Please close this item as fixed.

Please look for the attachments again.

Long details:

We are in the process of upgrading the web UI frontend system to the next version of the OS.  Doing this by cloning the system, then upgrading the clone, then testing the newly upgraded clone off to the side so that we don't thrash the production frontend too much while we work the bugs out of the new system.

The attachments previously were directly on the local system.  As you can imagine the clone would have a separate copy.  Then whichever system is in use and in testing would then have a "split brain" problem of new attachments might get added to one or the other.  That does not work very well if we switch in an upgraded frontend which has a separate attachment area.

In order to simplify the upgrade I moved the attachment area to an NFS mounted location where it would be shared between both of the frontend servers.  This is similar to what is done on the other systems.  That allows multiple systems to share access to the same storage area.  It allows both the old and new web UI frontend system to share access to the attachments directory.  One shared brain.  No split brain.

But the old system has a known buggy problem with NFS mounts timing out while looking for a kerberus daemon.  We aren't running kerberus and are affected by the old bug which has been fixed on the newer OS version.  So this is just a temporary problem on the old system while we set up the new one and will disappear entirely when we switch on the new system.

And then the old frontend happened to be rebooted and the NFS mount did not mount at boot time due to the bug in the old OS.  That made all of the attachments appear to have disappeared because the shared NFS directory as not mounted.  I am sorry.  I knew the system had gotten rebooted but I was distracted and it slipped my mind that the NFS mount would fail again when it booted.  I have just now manually mounted them again.  And therefore all of the attachments should be showing up again.  Assuming that was the problem here.  I assume that it was.

No, those two files were lost before that, unfortunately.

Is there a chance that my patches (the ones that got reported first to be missing):

may also be recovered along with the others or do I have to resubmit them in any case?

All attachment files in Savannah moved to a different directory on the server, they weren't lost.  I'm not aware of details about why this was done, so I'm reluctant to fix it myself.

Dear Savannah admins,

For the project "octave" I cannot download/access **any** file attached to a bug report or patch.

No access to the file.

On December 10, we got two messages by "Ineiev":

Did some severe data loss happen?
Can the data be recovered? (Just wrong permissions set?)

Thank you for your help,


Kai Torben Ohlhus <siko1056>
