December 16, 20223 yr Hi guys, As the title says, my cache drive is nearly full but there is no where near 750GB of files on it. Any ideas why and how to rectify? Here are some screenshots from Krusader and the GUI

December 16, 20223 yr Community Expert Looks like you have raid1 pool cache, 3x250 = 375 as I already noted And another raid1 pool cache_vms, 2x500 = 500. raid1 is a mirror. Sounds like you are expecting to use the total capacity of all drives in cache, which would require raid0 (if all are the same size) or single mode if different sizes in the pool. No redundancy with either of those modes.

December 16, 20223 yr Community Expert Something must have happened when you tried to convert it to raid0. I'll have to let @JorgeB take a look.

Just prior to posting I clicked "perform full balance", but then cancelled after reading forums and realising that it wasn't going to help. I wasn't attempting to change the RAID level.
December 16, 20223 yr Community Expert raid1 is default. After you get cache fixed up, your system share has files on the array.
December 16, 20223 yr Community Expert Any vdisks or other image type files there can grow with time if not trimmed/unmapped, do you have those type of files there?

G'Day @JorgeB, All VM vdisks are on the other cache pool. The docker image, System folder, appdata and a few folders waiting for mover are all that is on this cache pool. All folders had been selected when I grabbed the total file size in Krusader.
December 16, 20223 yr Community Expert Just the docker image should not account for that, unless it's a large image, could be appdata, only way to know is to move elsewhere and then move back, docker image is easy to just recreate.
December 16, 20223 yr Community Expert Also note that not sure Krusader shows the correct stats for btrfs, go to shares and click on compute to see if it's the same.
December 20, 20223 yr Author I finally worked it out. It was the lancache container's cache. It reported as practically empty but was hundreds of gigs. I moved to the array for now and will have a look at how to manage it's size better, assuming that it knows its own cached website data size correctly. Thanks @JorgeB & @trurl for trying to give me a hand!

I do have the same problem here: Unraid GUI shows me 353GB of space used Dynamix File explorer shows me 315GB of space used, I already recreatet my Docker Image which is 200GB in size, but that didnt change anything. Only Folders on this Cache Drive are: -appdata -logs -system I dont know what to do now.
