Does Linstor have the ability to sum up the volume of multiple nodes?

Hi~

For example, there are 3 satellites in linstor, each with a 10GB volume. Replication is not used in this environment.

In this case, is it possible to create a mkfs.ext file system on a satellite node with a combined size of about 30 GB?

In other words, is it possible to build a file system distributed across multiple nodes
using Linstor?

No. LINSTOR manages replicated volumes. The largest volume you would be able to create in your example cluster would be 10GiB.
