My Environment

  • ArangoDB Version: 3.4.7
  • Storage Engine: RocksDB
  • Deployment Mode: Single Server
  • Deployment Strategy: arangod from windows cmd
  • Configuration:
  • Infrastructure: windows pc
  • Operating System: windows 10
  • Total RAM in your machine: 16Gb
  • Disks in use: SSD(C:) and HDD(D&E)
  • Used Package:

I Stopped arangod from cmd using ctrl+c.
Then after sometime when I try to start it using arangod, I get this trace:

This is the first time I am using arangodb, so not sure what do I do to resolve this.

Hi @rahulserver,

Sorry for the late reply.

Whenever this error occurs, it is recommended to add the following WAL startup options:

--wal.ignore-logfile-errors <boolean>                       ignore logfile errors. this will read recoverable data from corrupted logfiles but ignore any unrecoverable data (default: false)
--wal.ignore-recovery-errors <boolean>                      continue recovery even if re-applying operations fails (default: false)

and restart the DBservers (the single instance in your case).

Once the deployment is up and running, you can remove those options again.

ArangoDB Version: 3.7.5
Storage Engine: RocksDB
Deployment Mode: Cluster
Deployment Strategy: Linux

How do we deal with this in the latest release with “ArangoDB Starter”。

Hi,
Please don't use old closed issues; messages may easily be overlooked there. Instead open a new issue, and reference the issue you feel is related to your issue.
You can add the referenced options to the starter via the pass through mechanism; for this case only the db-servers need this option - so use --dbservers.... .
