Hi All, I am having problems with a kickstart install of CentOS 8 When I try to do a completely automated install using PXE/UEFI it get to the point where it reads the kickstart config file. Then I see the following message "kickstart install Started cancel waiting for multipath siblings for nvme0n1" This is what I have in the kickstart file # Clear the Master Boot Record zerombr #

I have CentOS 8 install solely on one nvme drive and it works fine and relatively quickly. /dev/nvme0n1p4????????? 218G?? 50G? 168G? 23% / /dev/nvme0n1p2????????? 2.0G? 235M? 1.6G? 13% /boot /dev/nvme0n1p1????????? 200M? 6.8M? 194M?? 4% /boot/efi You might want to partition the device (p3 is swap) Alan On 13/10/2019 10:38, Jerry Geis wrote: > Hi All - I use qemu on my centOS 7.7 box that

Hi All - I use qemu on my centOS 7.7 box that has software raid of 2- SSD disks. I installed an nVME drive in the computer also. I tried to insall CentOS8 on it (the physical /dev/nvme0n1 with the -hda /dev/nvme0n1 as the disk. The process started installing but is really "slow" - I was expecting with the nvme device it would be much quicker. Is there something I am missing how to

From: Mihai Rusu <dizzy at google.com> This implements the device side for an NVMe vendor extension that reduces the number of MMIO writes which can result in a very large performance benefit in virtualized environments. See the following link for a description of the mechanism and the kernel NVMe driver changes to support this vendor extension:

Hi list, I'm running Centos 7.6 on an Corsair Force MP500 120 GB. Root fs is ext4 and this drive is ~1 year old. System works very well except on boot. During boot process I got always a file system check on nvme drive. Running smartctl on this drive I got this: === START OF SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED SMART/Health

Hi Rob & Mihai, I wrote vhost-nvme patches on top of Christoph's NVMe target. vhost-nvme still uses mmio. So the guest OS can run unmodified NVMe driver. But the tests I have done didn't show competitive performance compared to virtio-blk/virtio-scsi. The bottleneck is in mmio. Your nvme vendor extension patches reduces greatly the number of MMIO writes. So I'd like to push it

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags? Several things go wrong, and it's probably because of messy code, but I have a difficult time finding out what is the cause. Thanks very much, JeeBee. require(tcltk) || stop("Package tcltk is not available.") # Add path to

Hi, I've noticed huge write amplification problem with thinly provisioned logical volumes and I wondered if anyone can explain why it happens and if and how can be fixed. The behavior is the same on Centos 6.8 and Centos 7.2. I have a NVME card (Intel DC P3600 -2 TB) on which I create a thinly provisioned logical volume: pvcreate /dev/nvme0n1 vgcreate vgg /dev/nvme0n1 lvcreate

Hello all, and hope all is well Has anyone installed / on an nvme ssd for Cent 7? Would anyone know if that is supported? I have installed using Arch Linux, but at the time, mid last year, had to patch grub to recognize nvme. Arch is obviously running a much more recent kernel. Not afraid todo some empirical leg work. Just asking if anyone had tried already thanks all for any/all help regards

I have been following the patches on nvme support on the list and was wondering: If I wanted to build a vm host to be on the bleeding edge for nvme and spdk fun in libvirt, which linux distro -- fedora/ubuntu/centos/etc -- should I pick?
