SVN test repository

Original openafs-1.4.7 sources were checked into revision 2.

The URL is file://localhost/afs/ifh.de/user/f/ffrank/osd_svn. ACLs currently allow user ffrank only.

Creating the patch

{{{ cd trunk/openafs-1.4.7 svn diff -r 2:HEAD -x -b >| ../full-patch }}} The -x -b option (hopefully) causes svn to ignore changes in amount of whitespace (like diff -b).

iokaste crash recovery 2008-04-17

• syslog unconclusive
• AFS logs held no hints, either

  • update 2008-05-26: the problems with fs replaceosd were likely related to version mismatches between io and iokaste (fs != rxosd)

patch analysis

unidentified snippets

• src/viced/afsfileprocs.c:2472

  • Hartmut inserted an #ifdef AFS_NT40_ENV protecting two functions and some definitions. Probably a fix.

isolating vos splitvol

• sought through the patch, identifying places where
  • the client command was changed
  • the server was given the extra RPC

• used vimdiff to introduce changes into

  • rxgen file
  • vos implementation
  • volser implementation

  and added the new vol_split.c code file, therefore

  • also updating volser's Makefile.in

Conclusion

It turns out that the volsplit functionality depends on the reverse lookup functionality, also new with the full patch. Thus isolating volsplit failed at this stage and must be postponed until reverse lookups have been isolated.

Addendum

Apparently, InverseLookup is only used by vos splitvol, so both possibly belong in the same sub patch. For better
