=== High Memory Usage === | |||
Openfiler will cache all throughput, so as the NAS is used it will fill available memory. This is normal, and to be expected. Physical memory will be freed as required by other processes. If you suspect a problem, login to the console and run the <code>top</code> command. As long as the amount of swap memory in use is low there is no problem. | |||
See https://forums.openfiler.com/viewtopic.php?id=1017 for (a little) more info. | |||
If running OpenFiler on a VM, you may want to minimise the amount of physical memory assigned to the NAS. In which case keep an eye on the swap usage as you decrease the assigned physical memory, once it begins to rise you've gone a little too far. | |||
