Can you "temporarily" increasing the ClickHouse instance resource and try setting the TTL?
Updating TTL is a resource intensive operation.
t
Which resource? Disk space? There was enough disk space when I tried, but it failed and now I have run out of it.
Why? Isn’t it just deleting data older than the TTL?
Can I manually clear the clickhouse data while keeping all settings/configured dashboards?
p
are you using SigNoz in Docker Standalone or Kubernetes?
t
Docker standalone

Run the following to clear data of clickhouse and zookeeper:
Copy code
make clear-standalone-ch
make sure to bring down the signoz cluster first, followed by clean up, then back up.
t
Thanks I will try that. This will not delete users and other settings, right? 🙂
Related question: when transferring a Docker standalone instance to a new server, how do I backup/restore settings in an ideal way? Or simply move everything including volumes?

This will not delete users and other settings, right?
it will not. They are stored in SQLite DB file.
We do not have official guidelines on the backup/restore yet. For Docker Standalone, copying 
data
folder from 
deploy/docker/clickhouse-setup/data
should work fine.
