CBRESTORE - Connection reset by peer

Couchbase Server
21

Hello,
is there a solution in the meantime??? We backed up from 5.1.1 CE and tried to restore the data in Couchbase Server 6.0.1 Enterprise (Windows 10 and Redhat 7), same error as above.

thanks

Hello @weis

“Connection reset by peer” is a symptoms that can have many causes. I would recommend opening a new request and provided as much details as possible like:

  • Where is cbrestore being executed?
  • How many nodes in the cluster being restored to?
  • What versions of cbrestore is being used, the one provided by 5.1.1 CE or 6.0.1 EE?
  • What version of cbbackup was used to create the backup, 5.1.1 CE or 6.0.1 EE?
  • Provide the full stack trace if there is one?

I used the cbrestore tool from CB 5.0.1. Just had to download CB Server 5.0.1 and run the command as you showed.
Thank you @giles
