Particion vmware vcenter al 100% llena porque el fichero audit.log no ha sido rotado

 

/dev/sda3 - root partition 100% full due to Audit.log files not being rotated in vCenter Server Appliance (2149278)


Last Updated: 22/4/2020Categories: Troubleshooting 38 subscribe
 Symptoms
  • 100% capacity used for /dev/sda3.
  • Size of audit.log file is very large and /var/log/audit folder consumes majority of the space.
  • Saved logs from log rotate policy reference a date that is not in line with the policy.
  • Unable to connect to the vCenter Server as services are not started.
  • Running /etc/cron.daily/logrotate manually rotates logs as expected.
  • Accessing vSphere Web Client might fail with error: 503 service unavailable
 Purpose
This article provides steps to reduce the audit.log size.
 Resolution
To resolve this issue, truncate the audit.log file and verify the cron job is working correctly.
 

Truncate audit.log

  1. Log in to the vCenter Server Appliance through SSH.
  2. Run this command to enable access the Bash shell:

    shell.set --enabled true
     
  3. Type shell and press Enter.
  4. Navigate to the /var/log/audit folder with this command:

    cd /var/log/audit
     
  5. Run this command to verify the issue is with the audit.log file being too large (a few GBs):

    ls -lh

    For example:

    ls -lh

    total 3.5G
    -rw------- 1 root root 3.5G Feb 3 16:55 audit.log
    -rw------- 1 root root 445K Apr 8 2016 audit.log-20160408.bz2
    -rw------- 1 root root 447K Apr 9 2016 audit.log-20160409.bz2

     
  6. Truncate (clean the content without deleting the file) the audit.log file with this command:

truncate -s 0 audit.log
 

Verify that the cron job to rotate the audit.log is running

  1. Run this command to see when the cron job was last ran successfully:
ls -l /var/spool/cron/lastrun/

For example:

ls -l /var/spool/cron/lastrun/
total 0
-rw------- 1 root root 0 Apr 22 2016 cron.daily
-rw------- 1 root root 0 Apr 22 2016 cron.hourly
-rw------- 1 root root 0 Apr 21 2016 cron.weekly
 
  1. Determine if the cron job was last updated long time ago. Normally, this should be daily.
  2. Run this command to check for credential failures running the cron job:
 
grep "Authentication token is no longer valid; new one required" /var/log/messages.0.log | head
 
For example:

grep "Authentication token is no longer valid; new one required" /var/log/messages.0.log | head

2016-11-07T00:20:01.617180+00:00 vcenter /usr/sbin/cron[18972]: Authentication token is no longer valid; new one required
2016-11-07T00:20:01.617183+00:00 vcenter /usr/sbin/cron[18974]: Authentication token is no longer valid; new one required
 
  1. Run this command to check if the root password has expired:
 
chage -l root

For example:

chage -l root

Password change requested. Choose a new password.
Old Password:
New password:
 
  1. Change the root password as prompted.
  2. Verify the root account password has been changed:
chage -l root

For example:

chage -l root

Minimum: 0
Maximum: 365
Warning: 7
Inactive: -1
Last Change: Feb 03, 2017
Password Expires: Feb 03, 2018
Password Inactive: Never
Account Expires: Never
  1.  Restart all vCenter Server services.
service-control --stop --all
service-control --start --all

Note: Run the below command to change the root password to never expire:

#chage -m 0 -M 99999 -I -1 -E -1 root

ESXi Access to resource settings on the host is restricted to the server that is managing it

When you are trying to Login to the Vsphere you may receive a message “The host is currently being managed by the vCenter Server with IP Address xx.xx.xx.xx. Changes to this host during the session may not be reflected in the vSphere Client sessions currently viewing the vCenter Server.“Soon after you click “OK” when you get the above message and you proceed to deploy OVA, you may get an error “Access to resource settings on the host is restricted to the server that is managing it: xx.xx.xx“. This scenario is applicable when you are connected directly to an ESXi host managed in vCenter Server.

To resolve the issue, you have to follow the below method which is just a workaround:

Procedure to resolve:

  1. You need to stop communication between the vCenter Server and the host by stopping the below services. To do so, you need to either login to the console or SSH to the ESXi host. (To enable SSH on your ESXi host, follow the article share at the end of the resolution step)
    /etc/init.d/vpxa stop
    /etc/init.d/hostd restart
    When these commands are executed, the ESXi host will stop communicating with the vCenter Server.
  2. Deploy the OVA Template.
  3. Once your OVA Template is deployed,  start the VPXA service to add the ESXi host back to vCenter Server.]

/etc/init.d/vpxa start
That’s all !
