英文:
Why the .mods files cannot be loaded when updating to Apache IoTDB Version 1.0?
问题
有问题同步一些".mods"文件。
我已更新到Apache IoTDB版本1.0，先前IoTDB版本中的其他文件可以加载到版本1.0中，但这三个".mods"文件无法同步。然而，一些其他".mods"文件可以成功加载，但这三个文件不能。这个问题的原因可能是什么？
英文:
Having problem synchronizing some ".mods" files.
I have updated to Apache IoTDB Version 1.0, and other files in previous IoTDB version can be loaded into Version 1.0, but the three ".mods" files cannot be synchronized. However, some other ".mods" files can be successfully loaded, but these three files cannot. What may be the reason for this problem?

.mods是一个墓碑文件，记录了在Apache IoTDB中的命名tsfile中已经删除的数据。您可以检查这些数据是否已在版本1.0中删除，导致.mods文件无法同步。
如果这些数据未被删除，仅在同步时报告了这些“.mods”文件的错误，您可以检查时间序列名称是否有问题，并与版本1.0中使用反引号的规则进行比较并进行调整。错误也可能是由不符合反引号规则的命名引起的。
英文:
.mods is a tombstone file, which records which data in the named tsfile has been deleted in Apache IoTDB. You can check whether these data has already been deleted in Version 1.0, causing the .mods files cannot be synchronized.
If these data are not deleted, and only these ".mods" files reported error when synchronizing, you can check whether the name of time series has anything wrong, and adjust it compared with the rules for using backticks in Version 1.0. Error may also be caused by the naming that did not suit backticks rules.
