Question

我正在使用Couchbase Server 4.5.1。

我正在尝试cbrestore一个已在Ubuntu上使用cbbackup备份的存储桶，我收到以下异常：

/Applications/Couchbase\ Server.app/Contents/Resources/couchbase-core/bin/cbrestore . http://localhost:8091 -u Administrator -p st0ryplAyr --bucket-source=storyplayer-api --bucket-destination=storyplayer-api -v -x rehash=1

IndexError: list index out of range

我之前遇到了相同的错误（或类似错误），这就是我使用rehash=1选项的原因，但这次没有用。

关于我能做什么的任何想法？

我回答这个问题有点晚了，但是您必须在命令中添加“ -x rehash = 1”：

cbrestore ~/backups  http://127.0.0.1:8091  -u Administrator -p password -x rehash=1

为什么Couchbase在大多数操作系统上具有1024个vBucket，但是在Mac上只有64个vBucket（出于优化目的），因此您需要重新哈希以在所有vbucket之间重新分配数据。

在mac OS X上使用cbrestore的例外
