Unfortunately I didn't have success with the P410i. I tried several drivers and hacks that I found online, some of which even worked, but VERY unstable, totally unsuitable for a production environment. I ended up choosing to buy an LSI SAS 9201-16i PCI Express 2.0, which worked perfectly. By...

Hello everybody, I know the post is old, but I recently used it to enable HBA mode on DL360G7 and DL380G7 controllers. Everything perfect, just for one detail. One of my DL380G7 servers has 16 disk bays, so it has an expansion card, as the internal P410i only has two SAS connectors. This...

TKS!!! Thank you for your help! I hadn't noticed the "subtlety" of the difference.

Good point! Tks. So... the sequence of commands would be: root@hostname:~# zpool create -o ashift=12 mypool mirror /dev/sda /dev/sdb root@hostname:~# zpool create -o ashift=12 mypool mirror /dev/sdc /dev/sdd

OK. So just in case you opt for a RAID 10-like structure. Would I have to create two VDEVs with two disks each and a mirror between those two VDEVs? Stripe + mirror.

Do. Or do not. There is no try.

Dear colleagues, I'm setting up my first server with Proxmox in a test environment to later go to production. I've already used Proxmox at home in a simpler environment (only one XFS disk for the system and for storing the VMs). But this new scenario is very different and I want to try ZFS. The...

Hi jsterr, Yes. The 6 servers are on the same rack in the same room. Based on your answers and researching more on the subject, I concluded that scenario A will be better for my case, since if I opted for scenario B and a server from the Ceph cluster OR a server from the VM cluster...

I would like to ask a question that I am having. I have the following scenario, 6 HP Proliant DL360/380 G7 servers that I am wanting to create a Proxmox + Ceph cluster. All these servers have the same configurations: 2x Xeon E5630 Quad Core CPU, 48GB RAM, 4x 480GB SSD (connected using LSI SAS...

Ok.... and what is your suggestion? Note I Can’t install a HBA controller. Live long and prosper, Marcelo Magalhães Rio de Janeiro - BR

Hi Dragon19, note that the controller I mention does NOT have HBA mode. It is not an LSI, but an HPE P410i. Live long and prosper, Marcelo Magalhães Rio de Janeiro - BR

Hi Alwin, I know the requirements to not to use RAID between CEPH FS and hard disk. But server RAID controllers do not allow HBA mode, and the servers no longer have a PCI slot to add an extra controller. So ... what's less worse ... a RAID 0 for each disk on each server or a RAID 0 with all...

Dear friends, I have a question on assembling a Proxmox + CEPH (I am a newbie in Proxmox... but a have experience in use VMWare) cluster with 7 servers. My servers are a bit old, HPE DL360 and DL380 both generation 7 with P410i RAID controller (SAS 6Gb/s) that does not allow passthrough mode, ie...
