You can see 4 levels in the storage manager, that is the compress_zstd we are using.

Hi, I have the F4 423 with 4 HDD and 1 SSD as Hyper Cache.

I deleted the hyper cache (the OS is on the HDD), then it didn't show up anymore. I refreshed and the hyper cache also didn't show up. I turned off the device, removed the SSD and deleted the volume to use the SSD on other device.

When I turn on the NAS....... The NAS is not accessible anymore!!! What happened?!

How did you delete the Volume?

How did you delete the Volume?

- I went to the disk Management (or something like that) where it shows which drive is being used as hyper cache. I selected it and you can delete it. It showed some message and started deleting it for some time and when it finished, it disappeared. I then refreshed to see if that hyper cache drive disappeared. It did.
- then I turned off the device and removed the SSD.
- I installed SSD in an external box and deleted the volume to use that drive for something else
- the NAS turns on, makes the first "bip" but then it doesn't boot (at least completely) as it is not accessible nor makes the second "bip" from being totally loaded. The OS was on the HDD.
- when I connect the NAS to a monitor and keyboard, it only shows the BIOS logo, it doesn't go to the BIOS (I tried del, esc and F8)

My question is towards why did I delete the hyper cache and I refreshed to be sure that that was deleted and without the drive it won't work... Can someone help me?!

Update: thanks to Terramaster's support and EriChan

It worked. What happened then?
- it all happened when I properly deleted Hypercache, shutdown the NAS F4-423 and removed the SSD. When I turned on the NAS, it didn't do nothing but three first "bio" and all lights were on
- I plugged in a USB keyboard and HDMI to my TV. It showed that the NAS got stuck on the BIOS logo and it even didn't allow to enter the BIOS

What worked?
- turned off the NAS and took the energy cable out
- took the HDDs (mind the order!) out. In fact I did NOT take them really out, just unplugged the HDDs pulling the tray around 2 cm out but stayed in the slot.
- put the cable and turned on, then I pressed ESC or DEL on the keyboard several times
- now it went to the BIOS
- I changed the boot drive order to USB / HDDs / SSD (before it was, I think, SSD/HDD/USB
- saved and exit

It booted normally
