Subscribe

You can track all active APARs for this component.

 

APAR status

  • Closed as program error.

Error description

  • During backup operation cassandra container
creates backup files inside /tmp folder for temporary purposes.
After uploading to specific sftp/ftp/ebs location script does
not cleanup backup files which are temporarily stored /tmp
folder.

Local fix

  • Ø
Deleting cassandra pod will clear the files under /tmp and
allow the pod to start correctly

Problem summary

  • On every Cassandra backup operation ( can be trigerred by a cron
job or on demand operation), backup files are not cleaned in the
/tmp directory in each cassandra container. If backups are taken
too frequently, /tmp directly can fill up and cassandra startup
scripts which uses `sed` linux command will no longer work as
`sed` command needs space in /tmp directory.

This can result in downtime as cassandra servers do not start.

Problem conclusion

  • Fix targeted for release v2018.4.1.2

Temporary fix
