ScyllaDB is a high-performance, distributed NoSQL database designed for real-time big data applications. It is compatible with Apache Cassandra and offers low-latency and high-throughput capabilities. ScyllaDB is used for applications that require high availability and scalability.
One common issue encountered in ScyllaDB is the 'DiskFull' error. This issue arises when the disk space allocated for ScyllaDB is exhausted. Users may notice write operations failing, and there is a risk of potential data loss if the issue is not addressed promptly.
When the disk is full, you may encounter error messages in the logs indicating that write operations cannot be completed. Monitoring tools may also alert you to low disk space conditions.
The 'DiskFull' issue occurs when the storage capacity of the disk used by ScyllaDB is completely utilized. This prevents any further write operations, which can lead to application downtime and data inconsistency.
The primary cause of this issue is insufficient disk space to accommodate the data being written to the database. This can result from unexpected data growth, inadequate initial disk provisioning, or lack of regular maintenance to clear unnecessary data.
To resolve the 'DiskFull' issue, you can take several actions to free up space or increase storage capacity.
nodetool cleanup command to remove obsolete data from nodes after a topology change.nodetool compact to reclaim space by merging SSTables.Addressing the 'DiskFull' issue in ScyllaDB is crucial to maintaining database performance and preventing data loss. By regularly monitoring disk usage and implementing the steps outlined above, you can ensure that your ScyllaDB cluster remains healthy and efficient.
