(Digging up this email from 2004-11-04.)

I've just run into the same problem Yoann had. To refresh your memory (the
email above omits the details), "svnadmin recover holter/" gives the error:

svn: Berkeley DB error while opening 'copies' table for filesystem
/var/lib/svn/holter/db:
Invalid argument
svn: bdb: call implies an access method which is inconsistent with previous
calls

I tried "db_recover -vch holter/db/" to no avail.

Max said he recovered Yoann's repository. Is there some documentation on
how to do this? Is there a way to avoid this problem in the future? I
can't find any useful information on the "copies table type field corrupted
from btree to recno for no apparent reason" bug.

System info:
Fedora Core 1
Subversion 1.1.0
db 4.1.25
apache 2.0.50

Thanks in advance,

Matt
