Hi everybody, I want to install Proxmox 5.1 on HP DL380 Gen9 with UEFI Mode. I managed to switch the HP Smart array P440ar controller to HBA mode. The problem is that once Proxmox 5.1 is installed and the server is restarted... the server does not start on the "Proxmox" installation because it...

Thanks @fireon and @Belokan for your reply ! So I found this link that helped me. Here's what I did: I create new disk with "scsi" bus/device and the same size to current disk (who use virtio bus/device) I shutdown the VM and use "dd" command to copy current virtual disk data to new virtual...

Hi everybody ! I've VM's with virtio block bus/device and i noticed that I had better performances with a scsi bus/device. How 'i can move that for an existing VM disk ? Can someone give me a procedure to follow ? Thanks !

OK...I'm going to test this this afternoon on a server. Thank you very much for all your valuable advice. I'll keep you posted on my installation. Thank you again !

Thanks for this recommend ! ;)

thanks @guletz ! It's ok now ! I don't understand why i' can't do that to GUI ? For Blocksize option, What value do you recommend ? 16k or 32k ? I want use ZFS storage for VM and CT only. Thanks !

You mean that from the setup... you can choose to use the 2 disks I have assigned to the "/" in ZFS storage and continue installing Proxmox on them ?

Hi everybody ! Thanks @Alwin for your reply. [reply] I didn't realize that this HBA mode was the "IT mode" ! Thank you so much for explaining it to me. So if I understood the manipulation correctly, it would be necessary: Remove my server on my cluster Remove all RAIDs from the HP Smart...

Hi everybody, Thanks @guletz for your reply. Before posting, I had tried to create the storage via GUI but I couldn't realize this. See below: I don't see my ZFS storage coming from my node ! That's why I went through the creation of a directory... I didn't know it was not advisable ! Here's...

Thanks @guletz for your reply. Yeah... I'd already checked that out before I posted. See below my "/etc/pve/storage.cfg" ... dir: zfs-storage path /myzfspool content rootdir,images maxfiles 1 shared 1 Thanks.

Thanks @Andrew Hart for your link ! I increase the value for my pgs ;) Thanks @Alwin ! But...for my HP Smart array P440ar controller, i didn't found how disable RAID mode and use disk directly on Proxmox for ZFS storage. When set the controller in IT mode there is just a option where we can...

Thanks @Alwin but...how i can increase PG's on an existing pool ? I haven't figured out how to do it from GUI and I don't know the command line to use :( Can you give me the procedure to follow ? Thank you

Re, Also i try to restore a CT into my local ZFS storage and I've a error: Formatting '/myzfspool/images/101/vm-101-disk-2.raw', fmt=raw size=26843545600 mke2fs 1.43.4 (31-Jan-2017) Discarding device blocks: 4096/6553600 done Creating filesystem with 6553600 4k blocks and 1638400 inodes...

Hi everybody, I want to test ZFS local storage on 3 nodes. You can see below my config: Proxmox version: 5.1-35 Node-1: HP Proliant ML350 G6 32 Go RAM CPU X 16 (2 thread/core; 4 core/socket ; 2 sockets) Disk used for ZFS storage: 2 x 500 Go hdd SAS 15K ZFS journal into a 5Go partition on...

Re, I try to test hdds config into my HP Proliant DL 380 G9. This server have 8 bays and use a Smart array P440ar controller. The problem is that i can't bypass this controller when plug SAS hdd or SSD. When i run Proxmox server without create additional array via Smart array P440ar, we can't...

Re, Thanks @Alwin for your reply. I use http://ceph.com/pgcalc/ and suggest me 128 PGs (you can see the value for pool name "tkpool"). Does this seem fair to you because right now, with 64PGs (default value)... the cluster doesn't indicate that PGs are missing. Can we increase the number of PGS...

Hi everybody, Thank you very much @tom and @Alwin for your reply. I'll reconfigure my servers and keep you informed. Still a few more questions please: For some reason, if I want to temporarily run all my virtual machines on a single server, is it enough to have put (for 3 nodes cluster) 3/1...

Hello everybody, I'm newbie to Proxmox. I only have 2 servers to mount my Proxmox platform (i do not need the HA). I installed the Proxmox distribution (Virtual Environment 4.4-5 / c43015a5) on these 2 servers and I use DRBD as storage space. I managed to create some VMs (LXC, KVM) and run them...
