svnadmin recover — 使仓库数据库恢复到一致状态（仅适用于使用 bdb 后端的仓库）。此外，如果 repos/conf/passwd 不存在，它将创建一个默认的密码文件。
恢复挂起的仓库
$ svnadmin recover /usr/local/svn/repos/ Repository lock acquired. Please wait; recovering the repository may take some time... Recovery completed. The latest repos revision is 34.
恢复数据库需要对仓库进行排他锁定。（这是一种“数据库锁定”；请参阅 “锁定”的三种含义。）如果另一个进程正在访问仓库，那么 svnadmin recover 将报错
$ svnadmin recover /usr/local/svn/repos svn: Failed to get exclusive repository access; perhaps another process such as httpd, svnserve or svn has it open? $
但是，--wait 选项将导致 svnadmin recover 无限期地等待其他进程断开连接
$ svnadmin recover /usr/local/svn/repos --wait Waiting on repository lock; perhaps another process has it open? ### time goes by… Repository lock acquired. Please wait; recovering the repository may take some time... Recovery completed. The latest repos revision is 34.
