[PVE-User] New Disk on one node of Cluster.

[Сергей Цаболов]

Hi Eneko,

I make some test and found if one node remove from Cluster and restore 
the VM on it the VM disk performance is very well!

I have some ideas to test other methods about performance.

My question is: If I add to all nodes 2 or 1 ssd disks and move the 
*Ceph journal to SSD* disks my performance of VM and Ceph it will be 
better for virtual machines and?

With ceph journal on ssd ceph working better and fast?

Have someone such an experience move the Ceph journal to ssd?

And what ssd disk with GB is enough for journal?


Thank you.
