什么会导致亚马逊 ebs 分区上的数据存在时间间隙?
诚然,我们对 ebs 世界还是个新手。在 amazon ec2+ebs 上设置新的生产 couchdb 服务器后,我们遇到了一个问题,即大约 7 小时的数据消失了。以至于在该时间范围内,couchdb 日志中存在间隙。我们知道一切正常,然后我们开始遇到问题并意识到我们的数据库已重置为空状态。
想法?意见?猜想?
we're admitedly new to the ebs world. having set up a new production couchdb server on amazon ec2+ebs, we ran into an issue where about 7 hours worth of data simply disappeared. to the point where the couchdb logs have a gap in them for that very time frame. we know that things were working fine, then we started to experience issues and realized that our database had been reset to an empty state.
thoughts? opnions? conjectures?

问题是在正确安装 ebs 之前,couchdb 作为服务启动。这导致了令人困惑的行为。
the issue was that couchdb was starting up as a service, before the ebs was properly mounted. this caused the confusing behavoir.
