    After seeing this, I've just switched all my servers out to use awscli rather than s3cmd :)

    yeah seems it helps to now that AWS S3 has a Canada region (ca-central-1) so if you setup S3 bucket there, you should have faster transfers too from AWS S3 Canada to OVH BHS servers or if you have OVH France, then setup AWS S3 in Europe locale

    All the ones I'm backing up are in either GRA or RBX, and pushing them to eu-west-1

    My dedicated backup server is from SYS, so bandwidth is limited anyway, but nice I can use 100% of that limit.

    Nice to see this for the enterprise servers:
    I thought I read somewhere that they made everything 500 Mbps.

    Sucks that my first install failed. Not getting off to a good start. :(

    oh.. I see ! using centos original kernel ? ask OVH tech support if centos original kernel works with NVMe devices it could be like their Intel Xeon D where their drivers are only supported in OVH custom kernel out of the box and not supported under centos original kernel.

    I believe OVH uses Intel DC P3520 NVMe Intel® SSD DC P3520 Series: NVMe* SSD Performance

    Download Intel® SSD Data Center Family for NVMe Drivers and newer Download Intel® SSD Data Center Family for NVMe Drivers

    Yea, it appears I have to use the OVH kernel. Is there a post somewhere about how to install centos with the drivers you linked to and the org kernel?

    Can I use centmin mod with the OVH kernel?

    I've decided to get another server with SSD drives. They're going to credit the old server on my new server. Was really hoping for the NVMe drives. Oh well. SSDs are plenty fast.

    So is it specifically the drives that are the issue, or another part of the hardware missing drivers?

    Looks like it's the missing Intel NVMe P3520 drivers in the CentOS distro kernel. Don't have any experience with NVMe devices myself.

    I'm assuming that the NVMe drives were the issue. I know as much as what was in the support email I got.

    I sure hope I didn't purchase another server and throw away money. I hope the NVMe drives were the only issue. I just wrote the tech and asked. Should've done that first. But I think @eva2000 is probably right.

    Maybe useful

    https://www.ovh.co.uk/dedicated_servers/netboot.xml

    this is what i see on OVH MC-32 server a 4.9.13 Kernel vanilla i assume is non-GRSec based

    ovh-netboot-kernels-01.png
    i am using mdraid on /dev/md1

    ovh-netboot-kernels-02.png

    ovh-netboot-kernels-03.png

    confirm and reboot server

    Code (Text):
    uname -r
    4.9.13-xxxx-std-ipv6-64
    

    CentOS 7.3 default 3.10 kernel and 4.10.8 elrep mainline kernel both seem to have nvme support i think?
    Code (Text):
    locate nvme.ko

    but seems OVH custom 4.9.13 kernel doesn't
    Code (Text):
    modinfo nvme 
    modinfo: ERROR: Module alias nvme not found.
    

    try the 4.9.13 GRSec kernel
    Code (Text):
    uname -r
    4.9.13-xxxx-grs-ipv6-64
    
    lsmod
    libkmod: kmod_module_new_from_loaded: could not open /proc/modules: No such file or directory
    Error: could not get list of modules: No such file or directory
    

    OVH provided kernels aren't able to load modules ?

    Looks like it was the NVMe. Purchased a SSD version and installed org kernel.
    @eva2000 booting netboot with the experimental kernel doesn't work. Tried it and it faulted my NVMe box.

    Also got what is below. Is there an image I could use with the NVMe drivers? Could I use RHEL7 with centmin mod?

    that sounds like normal CentOS 7 or RHEL 7 iso original installs have NVMe support just OVH CentOS 7 installed via OVH manager images don't support NVMe then ??

    I am curious if I can setup custom kernel with NVMe added support via CentOS Kickstart file based install.

    Testing out CentOS 7 with VNC setup for gui access https://community.centminmod.com/th...ll-on-virtualbox-guest-server.730/#post-47746 so can use gui based system-config-kickstart to generate kickstart file on OVH as OVH doesn't have the default kickstart file that is created normally on CentOS installs at /root/anaconda-ks.cfg

    testing on local virtualbox before trying on OVH

    But why I got NVMe SSD working fine for a month now using orig kernel CentOS7?
