I have a 2TB cache drive in one of my servers that only has about 300GB free for some reason. How can I find out what is taking up all the space? 

Main Tab, Cache Devices, click on the little folder icon way to the right.

 

Or alternatively, binhex's Krusader app and navigate to the cache drive

 

Or another alternative, under the shares tab, click calculate on each share and it will show you where the files in the share are stored.

Thanks Squid, I've been using Krusader, and I deleted a lot of old stuff, but the cache drive is still showing same used and available space so I am still having a lot of trouble figuring out why it's so full.

Then you haven't deleted anything off of the cache drive, only out of the array.

So what is the easiest way to to determine what folders I am looking at in Krusader are actually on the cache drive?

Another way to see with what is full your cache drive is to open a Terminal from your Web GUI and run the following command:

Quote

root@Node804:~# du -sh /mnt/cache/*
4.3G    /mnt/cache/appdata
33G     /mnt/cache/domains
3.4G    /mnt/cache/share4all
21G     /mnt/cache/system
 

In my case the cache is used by appdata, domains, system and share4all - one of the shares which should be moved automatically to Array at a specific disk usage threshold.

So when I run that, this is what I get.

When I run fix common problems, I get these warnings, which I am not clear on how to resolve and I am unsure if they are part of the problem.

Please do a df -h /mnt/*

In my case this is what i get:

You can see the disk usage of cache drive as well as the disks from Array.

The Fix Common Problems warnings are telling you everithing you need to know:

appdata, Applications, downloads - should be (according to your configuration) on the cache drive, but somehow you move them to the array. 

Docker folder should not use the cache at all, the a folder Docker exist (empty or with content) on you cache drive.

You can use the tools mentioned in warnings to move your files where it should be. Always copy a file from a disk to a disk and from a share to a share!!! Do not mix disks with shares - there is a bug which will dostroy your data, if you do not respect that rule. See the following post for more details:
