Max,
Thanks for letting me know I was going down a dead end. Let me back up
a step and maybe someone can point me in the right direction.
We discovered we had a corrupted repository when running any svn client
command gave an error message suggesting we needed to do a recover on
the repository. Trying to do a simple "svnadmin recover" command on
the server resulted in a segfault crash. Trying to do a db_recover
from the repository's db directory resulted in panic messages
complaining about the format of the last log file. If I remove the
last log file in the db directory I can run svnadmin recover without
crashing but it gives the following error (and subsequent dump or
verify attempts fail with errors):
Repository lock acquired.
Please wait; recovering the repository may take some time...
Recovery completed.
The latest repos revision is 319.
svn: Berkeley DB error while closing 'strings' database for filesystem
curriculum/db:
Invalid argument
svn: bdb: DB_ENV->log_flush: LSN past current end-of-log
svn: bdb: DB_ENV->log_flush: LSN past current end-of-log
If I start from a fresh copy of the repository and delete the corrupted
log file, I can get "db_recover -vec" to run:
db_recover: Finding last valid log LSN: file: 227 offset 416244
db_recover: Recovery starting from [1][28]
db_recover: Recovery complete at Wed Apr 27 15:24:41 2005
db_recover: Maximum transaction ID 800264f1 Recovery checkpoint
[227][416292]
db_recover: Recovery complete at Wed Apr 27 15:24:41 2005
db_recover: Maximum transaction id 80000000 Recovery checkpoint
[227][416292]
And it looks good until I try to do a dump (or verify) in which case it
says:
* Dumped revision 0.

So this is where I currently am. I am not sure if there is anything
else I can try. Does anyone have any suggestions?
