IQ 15.2 集群数据库从备份恢复后启动时报错

最近有一个用户，从IQ 集群数据库的备份恢复成功后，启动时报以下错误：

 start_iq @idspiqdb.cfg -iqmpx_sn 1 -iqmpx_ov 1  -iqnotemp 100000 idspiqdb.db

从错误信息来看，问题原因是 -iqnotemp 参数设置的过大，为100G，而文件系统空间太小导致的。

注意：IQ集群数据库备份恢复成功后，启动时需要加上 -iqmpx_sn 1、 -iqmpx_ov 1和 -iqnotemp 参数。
-iqnotemp 单位为M，占用文件系统空间，启动成功后，需要add file到IQ_SYSTEM_TEMP DBSPACE下，然后stop server，去掉 -iqnotemp参数启动。
