Hello,

I have an NLS that is slowly running out of space. Currently there are about 300 GB free.

I have already added a 2nd server, which has significantly more disk space available, as a 2nd cluster node.

I have noticed that no virtual IP is created.

Now I have 2 questions.

What is the cluster functionality for if no virtual IP is created for the cluster?
All devices that I have configured, send their log data now continue only to the first node.

How can I replace the first server that runs out of disk space with a newer one with more disk space without loosing any data?

Thanks a lot

Hi

It sounds like there is a configuration problem. The two nodes should be using approximately the same
storage space. The functionality is such that all the data is captured in 5 pieces, aka shards. And in a
cluster shards 1,3,5 live on the master, and shards 2 and 4 live on the secondary. In addition to that,
shards 1,3,5 should be replicated to the secondary while shards 2 and 4 should be replicated to the master.

On the master node please run: and on the secondary node please run: then please send the resulting files to me:
/tmp/logstshmstr.tar.gz
/tmp/logstshsec.tar.gz

Thanks

Hi,
According to the "Total Elasticsearch Disk Usage" display, the master consumes 2.397 GiB of disk space and the slave consumes 585 GiB

The master generally has less disk space physically available than the new slave node

I send you the data.

Thanks

Hi,

1. Do you have a repository setup?
2. If so do both nodes have access to it?
3. On each node go to Admin, Snapshots & Maintenance, and please take a screenshot of the
Maintenance and Repository Settings tab.

Thank you

Hi,

i've added the screenshots.

They have a snapshot repos, but it's not a shared one.
Every node has it's own local repos configured.

Thanks

Hi,

It seems like your two nodes aren't really clustered. There is not supposed to be a virtual IP created, the master node
will delegate compute and storage to a slave node when things are configured properly.
