<div dir="ltr"><p class="MsoNormal">Has anyone successfully expanded the virtual disk size of
CUCM VMs without rebuild/DRS?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have an install where CM 10.5 is using the 2500 user
template and we want to increase to 7500 users. The 2500 OVA is 1 vCPU,
4GB, 1x80GB. The 7500 OVA is 2vCPU, 6 GB,
1x110GB. In the past, the older 7500 user CM versions had two
virtual 80 GB disks, however since 9.1 the 7500 user is a single 110 GB
disk. It seems like with a single virtual disk it would be easier
to expand an existing VM without rebuild.</p>

<p class="MsoNormal">There are several bugs on the topic:</p>

<p class="MsoNormal"> </p>
<p class="MsoNormal">In older CM versions there was a COP file to assist with
allowing the VM to use more disk when the vdisk was increased. However,
now I believe that it is just built in to CM to use more disk on reboots if it
detects a vdisk change instead of needing to run the OVA.</p>

<p class="MsoNormal">There is still conflicting documentation on the topic, so I
will probably open a TAC case but curious if anyone has dealt with this before?</p><p class="MsoNormal"><br></p><p class="MsoNormal">Justin</p></div>
