    cetrafs — Open-source shared-disk filesystem for Proxmox VE

    it's more something in qemu blockdev side, so it need patch on qemu-server. I'll try to see if it's improve performance when allocating blocks with for meshxfs && cetrafs. I don't known if somebody already done fio benchmark ? I had pretty poor results with ocfs2 && gfs2 in the past.

    cetrafs — Open-source shared-disk filesystem for Proxmox VE

    Hi great work ! I'll try to test it soon, compare with meshxfs. btw,they are a nice feature that we could add an qemu side: prealloc filter https://lists.nongnu.org/archive/html/qemu-devel/2020-08/msg02977.html It's for thin provisioning files, to prealloc dynamically the file by range...

    VM - Windows server 2025 - Memory used Max

    windows os is filling memory with zero at boot, so the memory is reserved on proxmox side. only way to trick it is to force ballon/unballon manually after boot to freeup memory.

    VXLAN with low bitrate transfer even with 10G SFP+.

    Thanks for the info ! Personnally, I'm using mellanox connect-x since multiple year with vxlan && bgp-evpn, and I never had problem with vxlan offloading I don't trust intel && broadcom anymore, too much bugs in their drivers

    [VirtIO NICs] Help understanding when to use multiqueue in VMs?

    It's mainly when you have a lot of (small) packets per second incoming. (If I remember, qemu is around 2millions pps with 1 core) try an iperf3 with 64bytes packets (to simulate a syn flood for example)

    Proxmox VE Ceph Compatibility with Dell PERC H965i on PowerEdge R670

    your pg number seem quite low, it could impact write performance with pg_lock. try to set pg target ratio to 1.0 in your ceph pool Also, verify in your bios that your server is set to max performance profile. (you want cpu always at their max frequency to lower latency)
