How to recover data from disk on a failed-over node?
When you have a node fail-over, is there a way to read data from files (vbuckets?) on disk for recovery purpose?
Robert, after a node is failed over, the files should still be available on the disk if you need to recover the data from them.
[EDIT] - Forgot to include "how" to do it. You'll want to use 'cbstransfer' (which is what cbbackup and cbrestore use under the hood). We refer to those files as "couchstore": http://www.couchbase.com/docs/couchbase-manual-2.1.0/couchbase-admin-cmd...
However, keep in mind that this should never be necessary since the data has been replicated to another node and the failover itself makes those replicas available.
Let us know if you have any other questions.
