Especially if you are planning to remove the old pool after you migrate, you shouldn't have any problems with this plan. If you were going to leave both running indefinitely, then I'd recommend calculating out how many PGs you should add based on how many OSDs you have. Based on your numbers, you might have too few PGs in your cluster, but adding 1024 temporarily should not be an issue.

I have a simple question I hope._______________________________________________I am moving our VM infrastructure from Xenserver to Proxmox. I only have one pool that has several RBD images that are mounted in Xen, that pool has 1024 PG's (30OSD's/3x replication).Question: I would like to create a new pool for Proxmox so I can have a clean slate going forward... Would it be bad to create a new pool with the same PG/Replication if I am going to remove the old pool after I have migrated the VM's over? Right now I am only using about 2TB out of 109TB.Cheers,
