Try Kernel 6.5.15

Yes it will work but Ceph hates Raid cards and likes the disks exposed directly. not sure if your card is going to pass these disks as native disks like in IT Mode. I would keep all of them in IT Mode (convert the card to IT mode and not in RAID Mode, enough articles available google for it -...

I got a reply in another thread, its due to RBD Plugin not supporting offline export as TPM is handled by a different service and this will be handled in a future upcoming release. Till such time we export the VM using backup and restore in new proxmox cluster. NON TPM VM are getting migrated...

Hi We have an EPYC 9554 based Cluster with 3x WD SN650 - NVME PCI-Gen4 15.36TB in each server. all backed by 100G Ethernet on Mellanox 2700 CX4 cards. output of lspci --- lspci | grep Ethernet 03:00.0 Ethernet controller: Broadcom Inc. and subsidiaries BCM57416 NetXtreme-E Dual-Media 10G RDMA...

I don't know, but I hate the RAID Cards on HP Servers, they are bad in my view

Hi Thomas, Looks like your disk is ok, is inter vm copy on the same host ok ? make a vm and try to copy within the vm's - it should be consistant at 100MBps approx as you have a 1Gbps card (without drops)

give the screenshot of - crystaldiskmark output in the vm and hdparm -Tt /dev/sda if you dont have hdparm do apt install hdparm -y

move the vm to a different disk - like the HDD and try to do the same there too and update us regarding the speed there

There is no problem. its confussion of Bits and Bytes Data transfer during copy is messured in Bytes - Big B. Speed is messured in bits - small B divide 960Mb/s by 8 to get the Bytes value = 120MB/s and you are getting 110 MB/s so its ok. speed drop is a different problem and needs to be...

Hi Team, Proxmox to Proxmox migration on old Proxmox RBD to new Proxmox RBD is supported now as I managed to do it. it works flawlessly. Moving VM from one cluster to another is so seamless that users will not even realize that they were moved from one cluster to another. Both clusters have...

I think RBD to RBD is supported now as I managed to do it just now for 1 VM. both the clusters have CEPH running and the VM on RBD successfully migrated to a new proxmox cluster on CEPH again. wonderful but another VM with TPM state did not work - any ideas for this

Hi Falk, I agree that Mellanox 4 is a PCI-E Gen3 card and even though I have a PCIe Gen5 board it will run at Gen3 speeds but at 16x its 15.7GByte/s which is more than 100Gbit/s so not sure if thats the bottleneck its somewhere else.

We had received them as IB and had changed them to Ethernet, and thanks for letting me know that we can only get upto 64 Gbit per port so its 6400MByte/s approx and its 4 channels (25G * 4 = 100G) intenrally so each channel should be limited to 1800MB/s * 4 channels but we are still nowhere near...

Will do that in the night today. VLAN1000 is so that we have the storage network segmented and nobody unauthorized has no access to it

Network Config of one of the host. We have 2 more hosts with different IP. We will have 5-6 nodes with 5-6 NVME SSD per node eventually and more as the workload increases.

Wow thats amazing
