Subject Error When Copying Data Files
Date Tue, 22 Nov 2016 03:36:15 GMT
Hi,

I'm seeing an error message when I'm trying to swap out an instance with another in a cluster
of three (I'm really trying to do backups and seeing if the restore works once I've copied
the data files to a new instance). What I'm doing is:

1.       Bringing down all three instances: couchOne, couchTwo, couchThree

2.       Copy all data files from couchOne to another directory, couchNew

3.       Start couchNew

4.       Start couchTwo, couchThree

Once I start the other instances (couchTwo & couchThree), couchNew returns an error:
[notice] 2016-11-22T03:16:20.591619Z couchNew@localhost <0.344.0> -------- Rescanning

couchTwo also has the same error after I started couchThree:

I'm still able to load the UI and it seems like nothing went down but I'm not sure why I'm
receiving this error or what it means. Does anyone have any ideas?  It only seems to happen
the first time I start the service (so far).

Thanks,

Maggie
