### Search before asking - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar. ### Fluss version 0.9.0 (latest release) ### Please describe the bug 🐞 When `TabletServers` are close to full disk usage, a `TabletServer` shutdown can trigger leader migration. For log tables, leader migration usually does not need to download much new data, so the existing data disk write protection limits the impact. For primary-key tables, however, making a replica leader may initialize KV state by downloading remote KV snapshots. If this happens while the target `TabletServers` is already above the data disk write-limit ratio, the snapshot download can fill the disk and make the cluster harder to recover. This can turn a single `TabletServer` shutdown under high disk usage into broader disk pressure across the cluster, because newly elected primary-key table leaders may consume additional local disk space during recovery. ### Solution _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
