Dear SVNers,
I'm trying to recover an SVN repository after a hard drive failure.
From 7,797 revisions, we lost the following seven (7) files from the
.../repo_dir/db/revs/7/ directory:
7437 (7-9 Dec 2009) (file also missing from revprops/ dir)
7461 (16 Dec 2009)
7519 (8 Jan 2010)
7520 (8 Jan 2010)
7521 (8 Jan 2010)
7679 (19 Mar 2010)
7683 (19 Mar 2010)
This single SVN repository contains many different software
projects/products. So I would prefer to be able to rebuild my
repository and only lose the revisions that explicitly depend on
those seven missing revs/ files, rather than having everything stop
at rev. 7436. Being able to recover all the way to 7797 might mean
only five products are affected but all our other products would
have their history fully restored, which would be excellent.
Is there a way to do this?
Can you still create dumpfiles containing the revisions that
did not get lost? If so, you could stitch together a new repository
and fill in the missing revisions manually (if you still know what
happened in those revisions, or can guess what happened).
See the svnbook section on rewriting history:
http://svnbook.red-bean.com/nightly/en/svn.reposadmin.maint.html#svn.reposadmin.maint.filtering
And see the section called "REVISIONIST HISTORY" of this file:
http://svn.apache.org/repos/asf/subversion/README
P.S. Other files may also be missing from the revprops/ dir, not
just 7437 -- If I'm willing to lose commit messages, can I live
without some revprops/ files?
You should recreate the revprops for all revisions.

Thank you, Stefan. The second file you mentioned,
http://svn.apache.org/repos/asf/subversion/README
refers to creating "no-op placeholder revision"s. Could someone expand
upon what these are and how to create them?
Thanks,
