10:31:53 Action: For all spaces other than temporary dbspaces, restore the space
containing the chunk from the archive. If this chunk belongs to a
temporary dbspace and if it is not the only chunk in that dbspace,
then drop and re-create the chunk. Otherwise drop and re-create
the temporary dbspace.

有备份就恢复备份吧，没备份就丢数据重新初始吧！
这么严重？什么原因造成的呢？回复 2# 大梦
感觉像是rootdbs的chunk1那个文件被破坏掉了！ 之前该数据库有正常运行过吗？
现在看起来是rootdbs无法访问，如果是阵列，是否有正确挂载？如果是文件，看看位置对不对。。
