Husker_N7242C Posted December 16, 2022 Share Posted December 16, 2022 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 Quote Link to comment

trurl Posted December 16, 2022 Share Posted December 16, 2022 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. Quote Link to comment

trurl Posted December 16, 2022 Share Posted December 16, 2022 Something must have happened when you tried to convert it to raid0. I'll have to let @JorgeB take a look. Quote Link to comment

I thought it was RAID0 from the start. 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. Quote Link to comment
trurl Posted December 16, 2022 Share Posted December 16, 2022 raid1 is default. After you get cache fixed up, your system share has files on the array. Quote Link to comment
JorgeB Posted December 16, 2022 Share Posted December 16, 2022 Any vdisks or other image type files there can grow with time if not trimmed/unmapped, do you have those type of files there? Quote Link to comment

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. Quote Link to comment
JorgeB Posted December 16, 2022 Share Posted December 16, 2022 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. Quote Link to comment
JorgeB Posted December 16, 2022 Share Posted December 16, 2022 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. Quote Link to comment
Husker_N7242C Posted December 20, 2022 Author Share Posted December 20, 2022 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! 1 Quote Link to comment
