NOT install to SSD NVMe

[drobicek]

Hello,
I can not install Proxmox 4.1 ISO to Intel SSD 750 Series NVMe PCIe SSD / Solid State Drive 800 gigabytes, there is a solution?
Mainboard is supermicro X10SDV-4C-TLN4F.
Thank you

Yes, the graphics menu loads the first drive /dev/nvme0n1 745GB, select the EXT4 filesystem and installation error - unable to get device for partition 1 on device /dev/nvme0n1. In text mode - proxinstall:2038 - dconf CRITICAL - read only file system, GPT data strukture destroyed,unable to get device for partition 1 on device /dev/nvme0n1......and more text.

You need to wait for the 4.2 install ISO (this is the first ISO with nvme support).

 

[drobicek]

and when will 4.2 ISO?
Thank you and very best PROXMOX,but do not war please.

Installation 4.2 ISO is now so successful, but when you start from the SSD writing error: volume group PVE not found and unable to fing LVM volume pve / root and other error listings, the system will not boot.
please help

Did a quick test and I have the same result. Before 4.2 I got a installation error now the installation works fine and after te reboot I have the same problem.

Hi,

I’m trying to do a new install of Proxmox 4.2 on a NVME boot drive (Samsung 950 pro), I'm trying to install with a Raid0 ZFS filesystem.

It fails when creating the partition.
In the GUI a popup shows ‘unable to create zfs root pool’ and in the install log:

GPT data structures destroyed! You may now partition the disk using disk or other utilities.
Creating new GPT entries.
Setting name!
partNum is 1
REALLY setting name!
The operation has completed successfully.
cannot create ‘rpool’: no such pool or dataset
unable to create zfs root pool
umount: /rpool/ROOT/pve-1/var/lib/vz: mount point not found
umount: /rpool/ROOT/pve-1/tmp: mount point not found
umount: /rpool/ROOT/pve-1/proc: mount point not found
umount: /rpool/ROOT/pve-1/sys: mount point not found

Did someone manage to install Proxmox on a nvme drive and zfs ?

RAID0

You must like data loss.

Add an delay to grub:

cat /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on rootdelay=5"

 

[drobicek]

I not have in /etc/default file GRUB, I got only ZFS

This is an default file, you must have it. I have only zfs too.

I tried adding "GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on rootdelay=5"" to etc/default/grub but still no joy booting into proxmox from my Intel 750. Any other steps required?

For clarity - it boots from the 750 but fails to find the LVM volume pve/root

 

[fabian]

try a bigger rootdelay (like 10 or 20) - this worked for us

 

[kn2mUc]

sorted, thank you Fabian. 10 did the trick....

Do I try to add these lines before starting the installer in debug mode? That file does not exist at that time for me... Should I create it?

the rootdelay is for after installation, not for during the installation. please describe your problem and hardware.
