How to enlarge single node cluster after having enlarged data disk?

Help Needed
1

We have a 2025.1.4 single node cluster on a Ubuntu 24.04 system. The installation of the cluster was accomplished with a 1TB logical volumne. Now we double the size of the logical volume and want also that the cluster is taking the new size into account. We suspect to use the command:

confd_client st_device_enlarge node: 11 devname: /exa/data/storage/dev.1 num_sectors: 0

but are not sure. The aim is to have the additional space to be used by temporary space which in our impression is only using the old size of 1TB as a space consuming job is failling when the sum of data volume and temporary volume is reaching the 1TB limit.

Kind regards

Dear Jörg

You are absolutely right, this is the correct command. You can find the documentation here: st_device_enlarge - ConfD | Exasol DB Documentation

You should get all needed information about your disk with the command confd_client st_node_list.

Search for the “name” tag e.g. name: /dev/sdb and use this to get the detailed info about your data disk with the following command, e.g.: confd_client st_device_info node_id: 11 devname: /dev/sdb

After that enlarge your volume with the command confd_client st_device_enlarge node: 11 devname: /dev/sdb num_sectors: 0

I hope that helps.

Best regards
