NAS hardware Why does my 1520 show almost full?

I have a 1520.
I get warnings that the unit is almost full. However, when I go in and look at my files, none of my files are that large. I have tried to delete files, but it doesn’t go down. In other words after I delete files it still shows it’s almost completely full.
Have also emptied my trash and going to the other processes that have been suggested for clearing things out.
Any ideas why my 1520 shows almost completely full?

Snapshots, multiple versions in synology drive, hardlinks, lotta things possible. What are you running on your nas other than hosting files?

I am just using it for hosting files.

Are you running synology drive or do you have backups running on it? You can quickly see shared folder size under control panel, expand the shared folder, this will hep you see which share is taking up the space. You can then investigate further by using file station to see the size of folders.

I think you'll need to do some digging.

Go to storage manager click on storage on the left, then the three dots on the right near the bottom in-line with your volume name and select 'usage details'. Does this help?

Most likely suspects are snapshots that still require those files.

I don’t think I am using snapshots. Where can I control that?

Maybe it's something else. What do the usage details say? You use 'Snapshot Replication' to manage snapshots.

My usage details show: shared folder = 2.1 TB, LUN 4.4 TB, Snology Drive 21.4 MB, Others 32.2 TB. What is "Others" and how can I check that? Also, I no longer use LUN. How can I delete that?

Run a storage report using Storage Reports.

Storage Manager has options to reclaim space. Some backup and other file operations create hidden leftovers that need to be cleaned up periodically.

Check recycle bins are empty and that they aren't enabled for folders that don't need them, especially backup and large file storage that are particularly active.

Yo vi algo similar en mi 918+, era debido a copia de seguridad de Synology Drive. Solo fui capaz de eliminarlo entrando por terminal SSH y navegar hasta las carpetas y borrarlas. DS File no era capaz de llegar hasta donde están esas copias!!!
