can not recover/export database
Hi, I am a relatively new subversion user/administrator. I have a big
problem with my database, and I am hoping that you all can help me recover
it.
The problem began with an error message on checkouts, telling me to recover
the database. I shut down the server and attempted to run 'svnadmin recover
/svn/' which gave the following error many times:
svn: bdb: Recovery function for LSN 24461 656348 failed on forward pass
Reading through this mailing list, I saw these two message threads:
http://svn.haxx.se/users/archive-2004-11/1047.shtml
(clearly the results of a google search, since it comes from different
archive)
I deleted the log.* files as suggested and ran the recovery again: it seemed
to work just fine. However, when I attempted to run 'svnadmin dump /svn/ >
/svn.dump' it wrote the first 10 or 12 revisions, then gave a LOT of errors
like so:
svn: bdb: DB_ENV->log_flush: LSN of 232/789010 past current end-of-log
of 1/4434
svn: bdb: Database environment corrupt; the wrong log files may have
been removed or incompatible database files imported from another
environment
followed by:
svn: bdb: strings: unable to flush page: 0
svn: bdb: txn_checkpoint: failed to flush the buffer cache Invalid
argument
Are there any further steps I can take to recover this directory?

You might try this recipe:
rm log.* __db.*
for i in *s; do mv ${i} ${i}-old && db_dump ${i}-old | db_load ${i}; done
svnadmin recover ..
