No, I add the new disk on node 7, not on each node of cluster.

Yes this I know how is make new rules
In one node I for test added 2 ssd disk and make the new rules|

|ceph osd crush rule create-replicated replicated_ssd default host ssd
and with this rule I make new pool vm.ssd

I want make new pool with HDD - SAS for specific storage of some Windows
Server VM.
In existing pools :
vm.pool base pool for VM disks
cephfs_data some disks and ISO and other datas
vm.ssd new pool I make from 2 ssd disk
I try to test the Windows Server disk speed for Read/Write and RND4K
Q32T1 with CrystalDiskMark 8.0.4x64
If I configure the VM disk to Sata and SSD emulation,Cache: Write back
and Discard, Speed write/read is very good something like :
SEQ1M Q8T1 1797.43/1713.07
SEQ1M Q1T1 1790.77/1350.55
but the RND4K Q32T1 and RND4K Q1T1 is not good, very small.
After the test I think if I add 2 new disks, configure is for specific
pool maybe my speed for RND4K Q32T1 and RND4K Q1T1 maybe they will get
better
Thank you
