我有一个cassandra集群的游乐场 - 服务器硬件上的7个节点（v.2.2.4）没有网络问题。 RF等于3。 对于加载数据，启动了生成测试数据的脚本。 A＆＃34;表＆＃34;有大约2b条记录。
我在执行脚本期间运行了子范围修复程序。结果，修复某些部分失败了。 然后开始升级执行程序，这也是错误执行的，所以 sstablescrub开始了。在sstablescrub过程之后，某些段的修复再次失败。
在我的案例中，哪些原因可以解决修复问题？
是否应在群集的每个节点上启动sstablescrub？
子范围修复的脚本。我希望它对某些人有用。
ring=( $($vCSBIN/nodetool ring | grep -oE '[-]?[0-9]{19}') )
for ((i=0; i<$((${#ring[@]}-1)); i++));
do
echo "st = ${ring[i]}, et = ${ring[i+1]}"
$vCSBIN/nodetool repair -st "${ring[i]}" -et "${ring[i+1]}"
done
