Ceph mixed disk size

[willybong]

Hello everyone,
I have a 3-node cluster with Ceph storage. Each node has 4 x 1TB SSD disks.
I would like to extend the Ceph storage by adding 4 x 4TB SSD disks to each node.

Will having different disk sizes cause any problems?

I'm considering creating a separate disk class, CRUSH rule, and pool to divide the data.
Any advice on this matter would be appreciated.
Thank you!

No, the different disk sizes are not an issue in the Ceph cluster.

That will a good idea.
