Hello @RubenjifImportant things to know before starting any opeartion on your fs are:What kind of FS are you using (use `lvs` or `mount` command for example)What the target partition layout for your needs (use the workbook proposedhere)What kind of box is it? VM, Bare-Metal, Public Cloud instance?You can share answers to questions above and we’ll try our best to help.Note that the safestway to manage this would be to install a new server , configure manually the partitioning through the ISO menu, and migrate the data from one box to the other.You will have a lot of touchy and manual operation to get an optimized fs organization to work with Centreon, consider the aformentionned option.
