Due to the unavailability of disk space, relocating logs to a different partition may be necessary. Unfortunately, the location of the log file cannot be changed. For more details, please refer to File Locations documentation. We do have an open feature request for it, but at this time, there's no ETA for its implementation. Alternatively, it is possible to mount /var as a separate partition/file system or use symbolic links to direct certain folders into a different partition/file system. The caveat is that it should be done before installing Redis on the node, as performing it when Redis is already running might introduce unexpected behavior.
