Update to 0.5: Unable to determine retention policy

[LeitLei]

Hi,

I followed your update guide to update from 0.4 to 0.5.
After sudo ./deploy.sh upgrade and entering the passwords, I've get the error:

[X] Setting the kibana system password, note the username will now be 'kibana_system' rather than 'kibana' {}
[X] Setting logstash writer role {"role":{"created":false}}
[X] Setting dashboard update role {"role":{"created":false}}
[X] Setting Elastic pipelines {"acknowledged":true}
[X] We think your main disk is 68G on /dev/mapper/ubuntu--v g-ubuntu--lv
[!] Unable to determine retention policy - exiting

Can I ignore this?

Best Regards
Patrick

Hi @LeitLei, Is your disk actually 68 GB?
With elastic default Watermarking set to 80% that would only give you 54.5GB of useable log storage.

The error above should be more verbose and point out that we are expecting a disk which has 100G+ of usable space for elastic, (so ~113 GB disk to account for OS install etc).

In relation to your specific case, your upgrade will not have completed sucessfully.

Thanks. After set the disk to 120GB, all works fine.

Best Regards
