Ensuring adequate free disk space is available on VMware vRealize Operations Manager 6.x nodes (2135651)

  • 5 Ratings

Purpose

This article provides information to ensure that adequate free disk space is available on VMware vRealize Operations Manager 6.x nodes.

If the disk space is insufficient:
  • You cannot upgrade vRealize Operations Manager
  • vRealize Operations manager may become inaccessible

Resolution

In VMware vRealize Operations Manager, all data and configuration information needed for normal operations is collected in the /storage/db file system.

To ensure that adequate free disk space is available on VMware vRealize Operations Manager 6.x nodes:

  • If the /storage/db file system is full, delete java heap dump files (.hprof). For more information on deleting java heap dump files, see vRealize Operations Manager 6.x is inaccessible, status of all nodes is Waiting for Analytics to Start

    If there is no adequate disk space available even after deleting java heap dump files, increase the disk space allocated to the /storage/db file system. For more information on adding additional storage, see Adding additional storage to the VMware vRealize Operations Manager 5.x Analytics or UI virtual machine.

  • If the /storage/log file system is full, archive the older log files to an alternate location by running these commands as the root user:

    mkdir /storage/db/archived_logs.$(date +%F)
    for file in $(find /storage/log -name \*.log.*); do mv $file /storage/db/archived_logs.$(date +%F)/; done
    tar -zcvf /storage/db/archived_logs.$(date +%F).tgz /storage/db/archived_logs.$(date +%F)
    rm -rf /storage/db/archived_logs.$(date +%F)/

    If there is no adequate disk space available even after archiving the older log files to an alternate location, increase the disk space allocated to the /storage/log file system.

  • If the /storage/core file system is used to store generated support bundles is full, delete older support bundles or move to a temporary location under /storage/db.

    If there is no adequate disk space available even after deleting/moving  older support bundles, increase the disk space allocated to the /storage/core file system.

  • If the / file system used is full, run this command to find files larger than 100MB and then delete them: 

    Note: The / file is primarily used for Linux operating system related files and requires less maintenance or interaction.

    find / -fstype local -size +100M

    The 100M parameter can be replaced as required.

    Caution: Ensure that files critical for the Linux operating system to function are not deleted from the / file system.

    If there is no adequate disk space available even after deleting files from / file, increase the disk space allocated to the / file system. For more information, see Increasing the size of the root partition on the VMware vRealize Operations Manager UI or Analytics virtual machine.
