I would like prepare before upgrade from vRLI 4.5 to 4.7.
We are using 3 nodes configuration and on every node i have similar situation after command df -h:
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 7.8G 3.6G 3.8G 49% /
udev 2.0G 128K 2.0G 1% /dev
tmpfs 2.0G 648K 2.0G 1% /dev/shm
/dev/sda1 128M 39M 83M 32% /boot
/dev/mapper/data-var 20G 8.0G 11G 43% /storage/var
/dev/mapper/data-core 158G 145G 5.2G 97% /storage/core
What should be safe capacity for vRLI...
a) for normal work
b) during upgrade
Can you give some your experience ?
Thanks

There is no specific doc which talks about exact space required for upgrade.
But it is told that enough space should be available. Depending upon type of deployment, whether it is small or, medium or large you can check on space that it need.
Cluster Deployment
Use a medium configuration, or larger, for the master and worker nodes in a vRealize Log Insight cluster. The number of events per second increases linearly with the number of nodes. For example, in a cluster of 3-12 nodes (2 nodes are not supported), the net in a 12 node cluster is 180,000 events per second (EPS) or 2.7 TB of events per day.
By default, the vRealize Log Insight virtual appliance uses the preset values for small configurations, which have 4 vCPUs, 8GB of virtual memory, and 510GB of disk space provisioned. vRealize Log Insight uses 100GB of the disk space to store raw data, index, metadata, and other information.
Please consider marking this answer as correct and helpful if this helps you.

/storage/core is where the log buckets are stored, and that is normal to see high utilization (it's expected). The update package does not get stored there and doesn't depend on that space being available, so you should be ok. Keep in mind you have to go through 4.6(.1) before you can go to 4.7. There is no direct 4.5 => 4.7 upgrade. Also, don't forget to snapshot prior to it.
Thanks.
This article has a good explanation too.
