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
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.
