Zstash Most Common FAQ

[forsyth2]

Why is my checksum bad?

If you get tarfile.InvalidHeaderError: bad checksum, one possible reason is that you tried to archive the log file into the directory being archived. This can corrupt files. An example of this, and how to recover from it, are in #335.

Why can't I authenticate into Globus?

Globus authentication has gotten tricky since the introduction of Globus consents. The recommended approach is to get it working on a toy directory before moving on to the directory you actually want to archive. For example, see the approach in #329 or #339.

Why is Globus timing out?

It used to be the case that Globus would only have to be re-authenticated roughly weekly on the web-interface and then zstash would pick up. Now though, Globus must be re-authenticated every 48 hours and anything after the first 48 hours has to be transferred manually with the Globus web interface. See #339.
