Investigation revealed that etcd's sync writes were extremely slow - around 250 kB/s with the default `virtio-blk` disk emulation. etcd requires fast sync writes (ideally under 10ms fsync latency) for stable operation. + +### The Problem + +The k3s logs showed etcd struggling with disk I/O: + +``` +{"level":"warn","msg":"apply request took too long","took":"4.996516657s","expected-duration":"100ms"} +{"level":"warn","msg":"slow fdatasync","took":"1.328469363s","expected-duration":"1s"} +``` + +A simple sync write benchmark confirmed the issue: + +```sh +[root@r0 ~]# dd if=/dev/zero of=/tmp/test bs=4k count=2000 oflag=dsync +8192000 bytes copied, 31.7058 s, 258 kB/s +``` + +### The Solution: Switch to NVMe Emulation + +Bhyve's NVMe emulation provides significantly better I/O performance than `virtio-blk`. + +### Step 1: Prepare the Guest OS + +Before changing the disk type, the guest needs NVMe drivers in the initramfs and LVM must be configured to scan all devices (not just those recorded during installation): + +```sh +[root@r0 ~]# cat > /etc/dracut.conf.d/nvme.conf << EOF +add_drivers+=" nvme nvme_core " +hostonly=no +EOF + +[root@r0 ~]# sed -i 's/# use_devicesfile = 1/use_devicesfile = 0/' /etc/lvm/lvm.conf +[root@r0 ~]# dracut -f +[root@r0 ~]# shutdown -h now +``` + +The `hostonly=no` setting ensures the initramfs includes drivers for hardware not currently present. The `use_devicesfile = 0` tells LVM to scan all block devices rather than only those recorded in `/etc/lvm/devices/system.devices` - this is important because the device path changes from `/dev/vda` to `/dev/nvme0n1`. + +### Step 2: Update the Bhyve Configuration + +On the FreeBSD host, update the VM configuration to use NVMe: + +```sh +paul@f0:~ % doas vm stop rocky +paul@f0:~ % doas vm configure rocky +``` + +Change `disk0_type` from `virtio-blk` to `nvme`: + +``` +disk0_type="nvme" +``` + +Then start the VM: + +```sh +paul@f0:~ % doas vm start rocky +``` + +### Benchmark Results + +After switching to NVMe emulation, the sync write performance improved dramatically: + +```sh +[root@r0 ~]# dd if=/dev/zero of=/tmp/test bs=4k count=2000 oflag=dsync +8192000 bytes copied, 0.330718 s, 24.8 MB/s +``` + +That's approximately **100x faster** than before (24.8 MB/s vs 258 kB/s). + +The etcd metrics also showed healthy fsync latencies: + +``` +etcd_disk_wal_fsync_duration_seconds_bucket{le="0.001"} 347 +etcd_disk_wal_fsync_duration_seconds_bucket{le="0.002"} 396 +etcd_disk_wal_fsync_duration_seconds_bucket{le="0.004"} 408 +``` + +Most fsyncs now complete in under 1ms, and there are no more "slow fdatasync" warnings in the logs. The k3s cluster is now stable without spurious leader elections. + +### Important Notes + +* Do NOT use `disk0_opts="nocache,direct"` with NVMe emulation - in my testing this actually made performance worse. +* The guest OS must have NVMe drivers in the initramfs before switching, otherwise it won't boot. +* LVM's devices file feature (enabled by default in RHEL 9 / Rocky Linux 9) must be disabled to allow booting from a different device path. + ## Conclusion Having Linux VMs running inside FreeBSD's Bhyve is a solid move for future f3s hosting in my home lab. Bhyve provides a reliable way to manage VMs without much hassle. With Linux VMs, I can tap into all the cool stuff (e.g., Kubernetes, eBPF, systemd) in the Linux world while keeping the steady reliability of FreeBSD. @@ -1,6 +1,6 @@ # Hello! -> This site was generated at 2025-12-26T01:27:25+02:00 by `Gemtexter` +> This site was generated at 2025-12-26T08:51:39+02:00 by `Gemtexter` Welcome to the foo.zone! diff --git a/uptime-stats.md b/uptime-stats.md index ed755a91..6ee7e128 100644 --- a/uptime-stats.md +++ b/uptime-stats.md @@ -1,6 +1,6 @@ # My machine uptime stats -> This site was last updated at 2025-12-26T01:27:25+02:00 +> This site was last updated at 2025-12-26T08:51:39+02:00 The following stats were collected via `uptimed` on all of my personal computers over many years and the output was generated by `guprecords`, the global uptime records stats analyser of mine. |
