CBFT error Full Virtual Disk

I have this error on the server, and not permit generate the data backup.

Hi @JohnFuse, The attached screenshot isn’t giving much clues on whats happening at your side.
Can you please let us know,

  1. Is this a deployment on containers/ VMs?
  2. Are you using FTS services or just that it got enabled as a part of the cluster?
  3. Any updates or observations in playing around with the memory limits?
  4. If the problem persists, then sharing the FTS logs would help us checking further.


Hi @sreeks
I have enabled on Indexes the Full Text and configure the views, but the server continues with using all memory.

Where is location to FTS Logs?



On linux systems the usual log path is : /opt/couchbase/var/lib/couchbase/logs/fts.log
Depending on the amount of data you are trying to index, need to provision / scale the FTS resources too. Please try to give more information about the number of documents in bucket, RAM/DISK sizes and the FTS memory quota set in your cluster.

Seems like you are on a older Couchbase release.
We have a highly optimised indexing format called “scorch” in the latest release 6.0 as against the older “mossStore” format. Highly recommend to check that out.

In meantime, you may also read about the - full text search best practices write up in our engineering blog to get an idea about few recommended index creation practices.


Hi @sreeks

I upload the logs on https://drive.google.com/open?id=1rtpk1hXodkc_f9dngAJvV69_F9TJx8q_ and the server has two buckets.
