    ZFS ARC vs VM page cache

    it's an interesting question... KSM only works with anonymous page cache which isn't the same as ARC which operates on file basis - see here https://www.kernel.org/doc/html/latest/admin-guide/mm/ksm.html to be honest I don't use ZFS with proxmox but I use it with freenas and used it with...

    [SOLVED] template creation with Packer: boot options menu appears on some cluster and not other

    hmm...so just to be clear: packer creates the vm on pve node starts the vm but at the boot screen you see the boot selection menu and not the debian installer ?

    NFS behaviors

    it depends if you use async for NFS then you might get an filesystem/io error for the vm's and need to repair it with fsck at the next boot if it is recoverable - depending when dirty flush happens. with sync param you might (flush) also get io errors but filesystem will be fine at next boot...

    [SOLVED] nfs mounts using wrong source ip/interface

    a small update and the solution: a few weeks ago we upgraded freenas but it was still mounting with the wrong ip/interface. today we updated proxmox to 6.4-13 with 5.4.151-1 kernel and that solved the problem without any further adjustment. so I guess at the end in what was a kernel bug but...

    Very weird VLAN issue (not 100% sure where to pinpoint the issue...)

    ok I'm asking 'cause I also had problems with lxc, though not with this pve version, which also had somehow the same symptoms you're describing and the problem was the tcp window became full after some seconds even with a simple apt update and then traffic stalled.

    Very weird VLAN issue (not 100% sure where to pinpoint the issue...)

    how does it look on netapp or switch side ? would it be possible to share the tcpdump from both sides ? is it happening when you transfer files to the nfs share or also in an idle state ?

    Very weird VLAN issue (not 100% sure where to pinpoint the issue...)

    anything in the logs ? traffic disrupted from the vm to the mounted nfs share or inside the vm itself or both ?

    Slow NFS Performance

    can you show output of mount | grep sto0 did you try any iperf test ? is it only slow from inside the VM or also from the pve host ? anything noteworthy in dmesg, syslog,etc... on pve host and sto01 ?
