Hi Donald,
I upgrade the Disk 3TB to 8x new 4TB. I rebuild the Disk step by step. I lose no Data!
How can this be true if...
If i want (open) the Logical Drive, the Mesage is: failed Mount disk8 fail: This disk does not have any mounted volume.
You have a RAID LUN and it's online.

If the volume won't mount, then there is some problem with the filesystem.
But this is concerning.

PD 1 was failed for PFA, (Predictive Failure Analysis) and you forced it online. If a disk with stale information is added to an array, it can cause unrepairable damage to the filesystem. This may be the reason the LUN can't be mounted. I would not recommend anyone use the force online command unless they understand how to use it safely.
PD1 has failed and it should be replaced. You should not reuse it or force it online.
