Hello,
When I try to back up Dremio on the coordinator node, as described in the documentation Back up Dremio | Dremio Documentation, I encounter the following error:
I’m not sure what I should do or how to proceed with the update.
Has anyone encountered this issue before, or can advise on how to resolve it?
@raaz19 When running dremio-admin, I assume Dremio is up. Can you paste the command you are using to kick off the backup? Also, can you try to run the backup to a different folder? (Other than /tmp)
yes sure @balaji.ramaswamy ,
here is an example: /dremio-admin backup -u dremio -p dremio123 -d /tmp/backup
also i tried to run the backup on another folder ‘~/backup‘ still have the same issue
Hello
@balaji.ramaswamy ,I also attempted to perform the backup on the master pod, but it did not work as expected.
dremio@dremio-master-0:/opt/dremio/bin$ ./dremio-admin backup -u dremio -p dremio123 -d /tmp/backup -a
Failed to create backup at /tmp/backup:
java.io.IOException: Status 500 (Internal Server Error): org.xerial.snappy.SnappyIOException: [EMPTY_INPUT] Cannot decompress empty stream (more info: )
I recommend checking the master logs (server.log), as they may contain useful clues or more detailed error messages.
@raaz19 Can you upload server.out and the dremio-admin-backup log (both under the log folder)?
