November 28, 2025Nov 28 Hello all,Today I installed three new SSDs and tried to create a new pool.However, after creating the pool, Unraid asks me to format all the disks. When I do this, it says that formatting is in progress, but after a while an error appears saying that the disks are unmountable.If I create a new pool using only the HDDs, everything works fine.Does anyone know what the problem could be? tower-diagnostics-20251128-2123.zip

November 30, 2025Nov 30 Author Solution Hello all,The issue has been resolved. There was still a folder with the same name in /mnt/.After deleting this folder, Unraid was able to build the ZFS pool successfully.
