LokiWALDisk SpaceOut of Disk SpaceDisk Full

Description

Loki is experiencing an out of disk space error due to the WAL (Write-Ahead Logging) filling up the disk. This can happen when the WAL is not properly configured or when the disk is full.\n

Mitigation

- Check the disk space usage of the WAL directory\n- If the disk is full, consider increasing the disk space or configuring a different disk for the WAL\n- If the WAL is not properly configured, consider setting the `-target` flag to a different directory\n
