Reduced Datalake cluster free space

marcocharlie — Tue, 21 Apr 2026 07:52:39 GMT

Hi folks,

I have a problem on my CDP Datalake causing failure on master node.
Apparently some services fail due to lack of free memory space.

Everything seems to work correctly but I don't know what can happen if the free space reduces further.

I have tried these solutions, however, with no effect if not momentary:
- lowering some alarm thresholds (from 10% to 7% of free space)
- removing some log files from the machine in /var/log and /tmp folders

@shehbazk Can you give me some advice?
And I would also like to understand if it is possible and how to increase the capacity higher than the current 236 GB.

Hi @marcocharlie

Greetings,

Yes, it is possible to increase the size, but I request please raise a support request because we need to share some internal doc's with you after reviewing the cluster.

Please do let us know once you created the support case.

Thanks,

Shehbaz.

Hi @shehbazk,

thank you for answering.

Unfortunately it seems that I do not have permissions to create or update cases.
