We have previously documented that volumes over 2TB can result in
inaccuracies, but this documentation does not say how the 'partition'
field in "fs listquota" can be inaccurate. It is confusing to see a
usage of 0% for a partition that you know is being used, so try to
briefly explain in what way this field is inaccurate.
The reason we _under_-report the partition usage is that the
fileserver actually gives back PartBlocksAvail and PartMaxBlocks (not
"blocks used" and "blocks total"). So 1TB used and 4TB total is
truncated to 2TB and given back as 2TB free and 2TB total. One we hit
3TB used we'll report it as 1TB free 2TB total (50%) when the actual
usage is 75%.

What's in the "doc" subdirectory ** doc/html original IBM html doc, no longer used ** doc/man-pages pod sources for man pages (converted from original IBM html source). ** doc/xml xml sources for manuals (converted from original IBM html source). there is some generated pdf/html content as well for the curious. Note that doc/xml/AdminReference uses doc/xml/AdminReference/pod2refentry to convert the pod man pages to xml for printing. pod goes directly to html just fine. The reference guide is now built by converting the existing pod documentation to xml. however, the indexing information was lost during the initial pod conversion. Someone we will need to try to get that back. ** doc/pdf old Transarc (and possibly pre-Transarc) protocol and API documentation for which we have no other source ** doc/txt doc/examples a few other miscellaneous files. From: Russ Allbery The Administrative Reference has been converted into separate POD man pages for each command, since that's basically what it already was (just in HTML). Considerable work remains to update that POD documentation to reflect the current behavior of OpenAFS (for example, there's no documentation of dynroot, no mention of Kerberos v5, many fileserver options are undocumented, the afsd switch documentation is out of date, and so forth). I've collected as many of those deficiencies as I know of in doc/man-pages/README. Any contributions to correct any of those deficiencies are very welcome. This is one easy place to start. The other reference manuals (the Administrator's Guide, the Quick Start Guide, and the User's Guide) are more manual-like in their structure. After some on-list discussion, we picked DocBook as the format to use going forward and the existing HTML files have been converted to DocBook with a script. This means that the markup could use a lot of cleaning up and the content is even less updated than the man pages. I did some *very* initial work on the Quick Start Guide, just to get the makefile working and to try some simple modifications. Simon Wilkinson is currently working on making more extensive modifications. If you want to work on the Quick Start Guide, please coordinate with him to avoid duplicate work. The Administrator's Guide and User's Guide have not yet been touched. Of those, the latter is probably in the best shape, in that the user commands and behavior haven't changed as much. If you'd like to start working on one of those, that would also be great.
