How to increase disk quotas
Increasing the storage capacity in Puhti and Mahti
The quotas of the scratch and projappl directories of Puhti and Mahti servers can be increased if needed.
You can use MyCSC to manage these quotas.
- Login to MyCSC and select the project you want to modify.
- In the Services list, click open the settings for Puhti or Mahti service as needed. This opens a page where the project manager can modify the quotas.
You can check the default limits of scratch and projappl areas from the table below.
|Directory||Default size||Maximum size||Default file number limit||Maximum file number limit|
|projappl||50 GiB||200 GiB||100 000||2 000 000|
|scratch||1 TiB||100 TiB||1 000 000||10 000 000|
Note that the extended quota consumes your CSC billing units regardless of how much data you actually have in the directory. See billing for details. Furthermore, even after the quota is increased, the automatic cleaning process will continue removing idle files from the scratch directory.
