Thank you for your answers so far! Without getting too much into a SATA vs NVMe topic, would SATA SSD's also do well in Ceph? Here I am thinking S4510 480GB SSD's, about 4 of them in each node.

Ok how would I achieve this? Would I simply bridge the 2 interfaces together on each node? EDIT: nevermind my question, I found the answer on the proxmox Wiki. :) But anyways, you believe this would be a good setup?

You are right, let me elaborate. They are not stacked the traditional way, but use the MLAG-technology (Arista switches). To avoid the traffic traversing the stack, would it perhaps be better to create 2 separate ceph networks with a port each, which connects to a different switch, thereby not...

Wait what, is that really true? Would it be wiser to use 10G SFP's with optic fiber? This I am aware of but what I believe you are saying is that it's better to stay with one CPU as long as possible? :) EDIT: I decided to google a little bit and Arista has a testing document that says that...

Hi wolfgang I am splitting the ports up in pairs. 2x10gb for vm traffic and 2x10 for ceph on each node. They all connect to a stacked 10gbe switch with DAC. It’s a dual socket system, however at the moment I only had the need to install one CPU.

PLEASE DO NOT USE THE GUIDE AT THAT LINK!!!! You will BRICK your H310 - if it’s the Mini Mono edition that connects to the special societ on the board!!!! I recently did this with my own R720xd and the thing is, you have both the Pcie version (which most people use), but there is also the Mini...

Hi Wolfgang, About 10 VDI machines currently, mysql clusters, web servee clusters, pfsense firewalls, VPS for some friends who rent for a community and some other stuff.. totally about 40 at the moment but it may grow of course.

Hi all, I am currently considering to do a 3-node ceph concept containing 3 of the following hosts: - Xeon E5-2690v3 - 128gb 2133mhz DDR4 ecc memory - 1.6TB P3600 NVMe (ceph storage) - 4x10GbE networking - optionally 6x 2.5” SSD’s (1 for bootdrive) I can expand the memory to 256gb and add...

Thank you, I had edited the /etc/corosync/corosync.conf file! Now that i changed the one in pve, it looks like it worked! just out of curiosity, was this really important to change back? I mean, the cluster looks to have worked nevertheless, I just noticed that it had the wrong address randomly.

Hi all, I have a proxmox cluster consisting of 2 hosts (pmx01, pmx02). Cluster name is cluster01 and consisted of 2 other hosts which are now gone (pve01, pve02). Now, so far most things seems to be working right (except for some qlge driver port flapping) but I have noticed some recent...

Hi all, I have recently setup a PVE 5.2-1 cluster of 2 hosts. I use a central NFS share to host the VM files. I wanted to install a new Server 2016 Essentials VM to replace our aging 2012 VM. I am using the 1705 version ISO of 2016 to install essentials. For storage controller I have selected...

Ah I see, that makes sense then. :) I have a different question though, I also have 8x WD Red (not the pro) and was wondering if these would perform okay as well? I would then get 4 more to fill up the chassis, the reason behind this is that the drives are 6tb so I would get a bit more space in...

I see, I just read that with bluestore, I wouldn't actually need any journaling device? Is this true?

Thank you for your help, I will give it a go! When you say used as block.db, do you mean as a journaling device?

Thank you for your response! I do also have some 1600Mhz memory but not enough to fully populate all the servers. I have heard various people saying that a 3-node cluster is not a good idea performance-wise. Is that so? I have a 4th node I could include too but would then have to get an extra...

Hi all, I am looking to setup 3 proxmox hosts and start hosting cloud services. I have a Dell C6220 box with 3 nodes of: 2x Xeon E5-2680 256gb quad rank 800mhz memory Dual port 10gbe nic In each node Inhave space for 4x 3,5” Drives and a single PCIe 3.0 low profile slot. Now which drives...
