    Proxmox loosing connectivity when VM starts network activity

    when you say virtual switch it means vmware isn't it ? does that mean you're running proxmox on a vmware host ?

    Proxmox loosing connectivity when VM starts network activity

    maybe duplicate ip or mac addr? what is syslog on pve node and switch telling when it happens? can you post your interface config from the switch?

    Ansible 'Operation not permitted' copying ssl keys directly

    first copy them to /tmp folder and then copy it from there to /etc/pve/nodes/. not very elegant but working, at least for me. ansible 2.7 and pve 6.2.

    High I/O wait with SSDs

    thanks I must say the iostats from the zpool are abysmal. just that you've something to compare: I've a 3x sandisk ultra 3d ssd (also consumer) in a mirrored zpool and this is what I get from fio. Run status group 0 (all jobs): WRITE: bw=672MiB/s (704MB/s), 83.0MiB/s-197MiB/s...

    High I/O wait with SSDs

    looks like it pl show the output of arcstat 1 and zpool iostat rpool 1 when you run the fio command.

    High I/O wait with SSDs

    that's certainly strange....is it possible for you to remove the rpool and use ext4 for testing ? to rule out the layers below...

    High I/O wait with SSDs

    also check your bios version. according to gigabyte version F4 has a fix "Improve SSD Performance" - whatever that means :)

    High I/O wait with SSDs

    ok I thought on zfs on linux (I'm on freebsd) you would see the vol/recordsize of the zpool but I looks like not. as the others already suggested check your vol/recordsize and the default 128kb should be fine. I'm in general rather reluctant to zfs benchmarks 'cause of the magic...

    for random IO you shouldn't use raidz1 or worse raidz2. use mirrored vdev. there're already multiple answers to this in the forum - just search it. if you want to improve sequential IO throughput you could use raidz1 but this of course depends on your IOPS workload. I would start without L2ARC...

    nfs mounts using wrong source ip/interface

    so I made an upgrade to 6.2 (5.4.60-1-pve) yesterday and the outcome is the same. also made an strace and a tcpdump. see tar. interesting is that initial nfs session is going via the correct interface and then beginning with SECINFO_NO_NAME (acording to rfc this handles the sec between client...

    High IO Delay

    lvm would be enough just to see if the io problem is zfs specific.

    High IO Delay

    Did you try it with something else except zfs?

    High IO Delay

    so the with the other server you've the same hardware and same zfs setup and "only" the ssd is different ?

    High IO Delay

    was the problem always there or when did it start to appear ? did you change something before that ? is it your first rodeo with zfs ? but the IO delay could also come from the NFS part isn't it ? can you give us an example with actual numbers pl
