If you are trying to resolve a disk full issue, it is recommended to review this article first. If you directly delete files, it could slow down the resolution of the issue.

First of all, deleting anything that is not explicitly documented as "can be safely deleted" below can lead to down time and definitive data loss. 

Important: Discovery has 2 different folders named ~ "log". One of them must not be modified.

• This folder CAN be modified: /usr/tideway/log/* (discovery logs)
• This folder must NOT be modified: /usr/tideway/var/tideway.db/logs/* (datastore transactions logs)

The files in the folders below can be safely deleted:

• /usr/tideway/cores/*. It is recommended to check this article first
• /usr/tideway/log/*. When the appliance is correctly sized, Discovery does not need manual actions to cleanup logs. If a manual cleanup is needed, disable the debug logs (if enabled) first. It is recommended to only delete what you need, starting from the oldest/biggest files. 
• /usr/tideway/var/record/**. It is recommended to disable the record mode (if enabled). See "recording mode" in this page.
• /usr/tideway/var/pool/**. It is recommended to disable the record mode (if enabled). See "recording mode" in this page.
• /usr/tideway/var/gather/*. This folder contains the files generated from Administration > Appliance Support.
• /usr/tideway/var/backup/**. This folder contains the local backup only. It has no link with the ones sent to ssh and SMB endpoints.
• /tmp/**. This folder is cleaned up after each reboots.

"*" means "all the files" in the folders above. There should be no subfolders to delete. For example: "rm -f /usr/tideway/cores/*"

"**" means "all the files and subfolders". For example: "rm -rf /usr/tideway/var/backup/*"

Note: If you have used scanner files in the appliance then be careful about deleting the file from pool folder, The pool data is always used for each subsequent discovery and returns identical results until the scanner file is updated or the pool data is deleted.
