Hello, Simply the model of disk not is detected by controller disk. I tested in other nodes and this model not detected. So I need change the position of SATA disk and have free slot to ssd. Not is problem of passthrough or config. Thanks!

So one of the controllers does not detect SSD disks, but the other does? This might be a config problem, you may need to mark disk as passthrough in controller BIOS/CLI utility. Some controllers can't do this; if that's the case you may have to create a RAID0 on that SSD disk. What controller(s) model(s)?

If you try, I suggest shutting the system down all the way, exchanging just two drives, then powering back on — and see if all is well before doing all. > > On which Ceph release were these OSDs deployed?
