While I cannot guarantee that you're the only site seeing such a thing, seeing messages like that for normal volume releases/moves/etc is not normal, and is cause for concern. In almost all cases, yes, that means the dump stream is corrupted in some way (especially if the reported values change). While I have seen that before, in all cases it was caused by either a bug or something mangling a dump incorrectly; in any case, there's nothing I know of in 1.6.9 that would cause that without something external messing with the dump stream. What would be interesting to see for that would be a copy of a dump of the volume. If there's nothing sensitive in the volume, you may want to just share a copy of the dump itself. Or, you can examine the dump yourself locally by running it through afsdump_scan, a tool to interpret the contents of volume dumps. A copy of that with some extra fixes applied to it can be found here: <https://github.com/openafs-contrib/cmu-dumpscan/tree/fixes> I would dump the volume using 'vos dump' (specifically the RO clone on the RW site, since this is for a release), and run: $ afsdump_scan -PBHVvi /path/to/volume.dump And you should see a bunch of info about the files in the dump. If there is a problem with the dump, afsdump_scan should print out a somewhat similiar message as you saw, complaining about an unrecognized tag. -- Andrew Deason adea...@sinenomine.net _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
