Hi Sergey,
So, does this really make sense? If you put the new 2 disks in node7 in
a pool, that data won't be able to survive node7 failure.
If you're trying to benchmark the disks, that wouldn't be a good test,
because in a real deployment disk IO for only one VM would be worse (due
to replication and network latencies).
What IOPS are you getting in your 4K tests? You won't get near direct
disk IOPS...
Did you try with multiple parallel VMs? Aggregate 4K results should be
much better :)
Cheers

I have 7 node's PVE Cluster + Ceph storage
In 7 node I add new 2 disks and want to make specific new osd pool
on Ceph.
Is possible with new disk create specific pool ?
You are adding 2 additional disk in each node, right?
No, I add the new disk on node 7, not on each node of cluster.
You can assign them to a new pool, creating custom crush rules.
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

Why do you want to use those disks for a different pool? What disks
do you have now, and what disk are the new? (for example, are all HDD
or 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
Cheers
