mon ceph osd tree

[yangsm88888]

I am new to vitastor. How to add and delete Mon? Is there any similar display command for ceph osd tree? If the cluster has SSD and HDD disks, can I manually create two types of pools? Detailed configuration parameters of RDMA, thank you

Hi

How to add and delete Mon?

Just enable vitastor-mon unit on the required nodes and that's all.

Is there any similar display command for ceph osd tree?

Not yet, but coming soon :)

If the cluster has SSD and HDD disks, can I manually create two types of pools?

Yes, check osd tags in docs (README -> Pool Configuration)

Detailed configuration parameters of RDMA, thank you

Usually you only need 1 parameter: rdma_gid_index=3 for Mellanox RoCEv2 and everything works. 3 is taken from ibv_devinfo -v output. For other parameters check docs (README -> Features -> click on RDMA).
