Error during restore using cbrestore


#1

[Couchbase Version 2.0.1]

Hello,

I am trying to restore the data backed up using cbbackup to a new cluster. The amount of data is large ~630GB.
I am using cbrestore and it runs for some time and fails when it has completed around 50% to 55% of the restore. The following is the error we see. There is no other information/logs that can give us any information on what is the root cause.

I have tried this multiple times and it fails around the 50% mark. Any pointers on what could be the issue and how to overcome this?

Thanks!
