dnsmasq.log - root partition is full VCSA 6.5

In the Morning got alerts regarding the VCSA Health ,I logged to VCSA Management Interface 

https://vcentercerver:5480

I can see some Helth warning on VCSA, SSH to VCSA using putty and immediately Noticed that  /root partition is full..



Then I dig deeper to find which files causing the issue and find the culprit bunch of dnsmasq.log files were created in the /var/log directory.  



Found KB related the issue that I'm having .. seems like it is safe to remove larger log files as a quick solution, it cleared most of the space and now I have free space.. 




Still I need a permanent solution for this .. Time to follow the KB and add parameters to Log rotate..   

First edit Log rotate for dnsmasq

vi /etc/logrotate.d/dnsmasq
Update the file to contain these lines and save the file:
/var/log/vmware/dnsmasq.log {
nodateext
daily
missingok
notifempty
compress
maxsize 5M
rotate 5
sharedscripts
postrotate
[ ! -f /var/run/dnsmasq.pid ] || kill -USR2 `cat /var/run/dnsmasq.pid`
endscript
create 0640 dnsmasq dnsmasq
}


Then update the dnsmasq.conf

vi /etc/dnsmasq.conf

Update the file to contain these lines and save the file:

listen-address=127.0.0.1
bind-interfaces
user=dnsmasq
group=dnsmasq

no-negcache
no-hosts
log-queries
log-facility=/var/log/vmware/dnsmasq.log
domain-needed
dns-forward-max=150
cache-size=8192
neg-ttl=3600 

finally restart dnsmasq service

service dnsmasq restart 

new log files are much smaller and they are zipped.

 

VMware KB shows that this issue resolved in below version.

Disk size expansion issue - Vmware 6.0 Issue - adding/Expanding Disks size ) >= 2TB not allowed

Disk size expansion issue -  Vmware 6.0 Issue  -  adding/Expanding Disks size ) >= 2TB not allowed  



Error - 


Hot-extend was invoked with size (8178892800 sectors) >= 2TB. Hot-extend beyond or equal to 2TB is not supported.











Solution -
Once shutdown we were able to completed the Disk Expansion. Is seems like an issue with VMware 6.0 , once Host upgrade to Esxi 6.5 and HW version to 13 we can do the Disk expansion on the fly.
