mismatch while reading representation
Hello All,
I posted this on the user list but got no reply. My apologies if this
is not the appropriate place to post.
I'm trying to migrate a subversion repository from a linux system to a
windows system using svnadmin dump and svnadmin load. Unfortunately,
when I get to a particular revision (a relatively large revision -
~700MB) I get the following error:
svnadmin: Checksum mismatch while reading representation:
expected: 5a61669a554808ffb94c0542b79a6d5f
actual: 5a55203a7809f159b4271a4dcec97684
I came across this on the web:
http://ilovett.com/blog/programming/subversion-checksum-error
which describes a similar error and recommends manually repairing the
database. One of the cited commands is:
db_dump -kp representations > representations.dump
which is to be executed within the db directory of the repository.
However, my repository does not have a "representations" directory or
file. Perhaps my repository is using a different database (i.e. not
Berkeley)? Any other suggestions as to how to migrate the repository?

Sounds like a revision is corrupt. fsfsverify may be able to fix it.
You can download it from:
http://www.szakmeister.net/fsfsverify/
If you still have an issue, email me privately with a link of where to
download the bad revision and I can likely repair it.
HTH!

Thanks for the reply, I'll try fsfsverify. I'll let you know how it
goes, and thanks for the offer of manually repairing it. I may take you
up on it yet :)
