RE: [Zope] All Of My Zope 2.6 Transactions Since 2/6/07 Are Gone!
I know of 2 situations where such things can happen unexpectedly: Thanks for the assistance. I was able to recover using an XML data backup outside of Zope and move the missing content as flat files to the Apache document root on a new server. Since I have decided to abandon the old machine now I won't bother to investigate why the data disappeared. What is the lesson learned? That when you are using an old (2.6.2) version of Zope there is an increased likelihood of something bad happening. Presumably Zope 2 gets more stable with later versions. So use Yum to upgrade Zope 2 regularly. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Zope Undo shows incorrectly that there were no transactions between 2/6/07 and 3/28/07 when the data loss occurred. Zope by itself cannot loose content: It stores data (by default) in a FileStorage and a FileStorage is a transaction log file. All modifications are additional transaction logs appended to the file. If you see that the latest transactions are lost, then someone else modified the storage. I know of 2 situations where such things can happen unexpectedly: * When you move or remove an open file under *nix, then all processes that have this file open continue to use it (even though it is now in a different place). Any new process, however, may no longer see modifications done after the move/remove (at least not at the original place). * About 2 years ago, one of my disks started to die. Linux gave me the impression that my work proceeds, just a bit slow and with tons of disk problem reports. The warning signals have been heavy enough. I made a complete backup. That was very wise because after a Linux restart, my work has been wiped out: Linux had been no longer able to store my changes on disk. It had worked only in its buffers -- and after the restart, the buffers were empty. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Have you checked the Data.fs to determine if it has been coddled? How large is the Data.fs? Which version of Python are you using to run Zope?
