Downloading logs from Ops Manger UI or BOSH CLI failed with "gzip: stdout: No space left on device"

Issue/Introduction

When trying to download logs from the Ops Manager web UI, it fails with the error message "gzip: stdout: No space left on device". You receive the same error when executing the bosh logs command.

If you run df -h on the BOSH director VM, it shows that the device for /var/vcap/data was only configured to a size of 16GB, which is quite small.

It can then be observed that the BOSH Director VM was set to vm_type of xlarge (cpu:4, ram:16GB, disk:32GB). Since the same amount of memory capacity and disk space will be allocated by default for other purposes, the BOSH Director VM has only 16GB left for /var/vcap/data.

Environment

Product Version: 2.5

Resolution

The BOSH Director VM vm_type set to xlarge must be changed to xlarge.disk to keep the same CPU or memory capacity and allow for larger disk capacity.
