svnsync: E000022: Couldn't get lock on destination repos after 10 attempts

出现问题的原因

发生以上情况的有以下几种情况：

  1. 有正在同步的进程未完成，lock未释放；
  2. 上一次同步的进程异常导致中断，lock未释放。
  3. 有svn冲突

SVN同步时，源库端会在目标库端加lock，成功同步后释放lock，但当SVN同步异常中断后，lock是不会自动释放的。这时在执行svn sync命令，就会出现如上问题。

解决方案

执行以下命令：

1
svn propdel svn:sync-lock --revprop -r 0 http://192.168.xx.xx/仓库(svn仓库地址)

将lock释放即可再次执行同步。

1
svn propdel svn:sync-lock --revprop -r 0 file:///www/svndata/test

我自己操作成功的命令如下所示：

C:\Users\ZSYY\Repositories>svn propdel svn:sync-lock --revprop -r 0 file:///C:\Users\ZSYY\Repositories\Study
property 'svn:sync-lock' deleted from repository revision 0
