Symptoms

The size of / on any vRealize Operations node is less than 20GB

Note: Hard drive 1 (/dev/sda) needs to be at least 20gb. The root filesystem (typically /dev/sda4) within, needs to be at least 16gb

The vRealize Operations Admin UI is inaccessible.

Logging into the vRealize Operations Primary node Console as root shows the error:

ERROR install.sh: Re-create partition table on /dev/sda

Cause

vRealize Operations 6.0.x nodes have a /dev/sda3 file system, mounted as the / partition, with a size of 12GB while PhotonOS requires at least 20GB for the / partition.
This difference in size will cause the upgrade to vRealize Operations 8.x to hang, as Photon OS requires more space.

Note: Hard drive 1 (/dev/sda) needs to be at least 20gb. the root (typically /dev/sda4) filesystem within, needs to be at least 16gb

Environments that started with nodes on vRealize Operations 6.0.x will encounter this issue.
