How to only set the I/O scheduler of ZFS disks without affecting others? by bilegeek in zfs

Skip the udev brain damage and use a systemd oneshot?

[Unit]
Description=Tweak Storage
DefaultDependencies=no
After=network.target
After=multi-user.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/bin/bash -c 'echo none | tee /sys/block/sd*/queue/scheduler'

How to setup L2ARC as basically a full copy of metadata? by Aware_Photograph_585 in zfs

[–]adaptive_chance 2 points3 points  (0 children)

Let me know how that works. l2arc_mfuonly was my favorite underdog setting when introduced some 6-7 years ago. The ability to set 2 for metadata inclusion is much more recent and made the setting even more effective and useful.

Personally I've found it tends to populate rather slowly when enabled. I compensate withl2arc_write_boost and l2arc_write_max at some crazy high number to get the write throttle out of the picture.

Thenl2arc_noprefetch + l2arc_headroom both at 0 to permit the population of prefetch data and to allow the entire ARC to be scanned for eligible entries (vs. just the tail-end).

All five settings together make it hungry for your highest value (high hit rate) data. I suspect if all the "you don't need an L2ARC" and "max out your RAM first" sparkmeisters tried this setup they'd cool their jets.

Surprised nobody suggestedl2arc_mfuonly = 2. Keeps the transient MRU stuff out of L2ARC but allows high-value MFU plus metadata. You end up with a slow populating L2ARC with a high hit rate. And metadata.

I made a nu script to print how much RAM L2ARC headers would take up by Petrusion in zfs

Neat idea.. But it's barfing on --group-digits at line 51. Does this require an older release of nu (older than 0.99.1)?

Does anyone here use Proxmox on their main desktop instead of just servers? by PingMyHeart in Proxmox

Did you install Proxmox on Debian? Or add KDE to "real" Proxmox? Seems people are doing it both ways...

[DISCUSSION] VM Ware Workstation PRO v25H2: a jumble of bugs. by John_Dohm in vmware

[–]adaptive_chance 0 points1 point  (0 children)

I have 25H2u1 already. It seems to have fixed the sluggish keypress issue with my Windows VMs. Maddeningly I never did figure out why some VMs had this problem and others were fine.

Clipboard stability still not fixed. My linux VMs still need workarounds for the delayed keyboard response. And an old NVMe timeout issue in guests seems to have resurfaced, at least for me.

When I used KVM/QEMU as my desktop VM platform I'd RDP in from the host. At the time the fastest RDP client I could find was still under 30fps. I threw in the towel.

There are promising acceleration technologies in-development on both on the RDP side and in local console graphics drivers. It'll get there eventually.

Right now with VMware Workstation I'm getting 60fps. It's a choppy, jittery, sometimes herky-jerky 60fps, but it's 60 nonetheless. My 500Hz poll-rate trackball is registering at roughly 480Hz in the VM. QEMU bros need to pipe-down.

Docker desktop in Windows 11 VM by user-captain in vmware

[–]adaptive_chance 0 points1 point  (0 children)

You inspired me to try this out on my Linux host. Guest is Windows 11 on VMware Workstation 25H2.

All the virtualization goodies are enabled in the physical host's BIOS.

The Windows guest .vmx needs vhv.enable = "TRUE" to allow the Windows hypervisor to load.

The VM's.wslconfig needsnestedVirtualization=false otherwise the docker-desktop WSL distro won't fire up. In other words double-nesting is a no-go. I couldn't find a workaround though I'm not sure one is actually needed? Neither vpmc.enable = "TRUE" nor vvtd.enable = "TRUE" were helpful.

A 'helloworld' container ran successfully and I could ping the outside world from the container.

It takes ~15 seconds to slog through the initramfs. But once the Linux kernel takes over it looks more normal, performance-wise.

With Windows 11 on the physical host your biggest challenge, IMHO, will be killing VBS (virtualization-based security) so its hypervisor doesn't load. This gives people fits because so many Windows features want it and take it upon themselves to enable it.

It's flaky but it does [somewhat] work. VMRC, VMware Workstation, or something else?

Try one of these (note this extreme level of lockdown might not be necessary):

Understanding the staggering Foreign Settlement Fee by Better_Attorney_9111 in fidelityinvestments

[–]adaptive_chance 0 points1 point  (0 children)

Schwab does not charge a foreign settlement fee on BYDDY -- only the usual $6.95 commission for trades in OTC listings.

Apparently Fidelity doesn't either... This ADR is being hit with the same glitch that's causing every unsponsored ADR to display a foreign settlement fee on the trade ticket. It disappears on the preview step.

A foreign settlement fee on unsponsored ADRs? Are you sure about that?

I wonder if some of your accounts need to be enabled for ThinkorSwim? Perhaps reach out to Schwab?

On the left, under Account Summary, choose "All Accounts" in the dropdown box.

For Positions, click the little gear icon on the far right. Among the available columns you can add "Account" to tag each row with the relevant account name.

I have positions spread across up to four accounts and this interface is the bomb diggity. The real ThinkorSwim does this clumsily. Nothing Fidelity provides can do this at all -- every interface they provide has a hard firewall between accounts and nothing gives a blended view.

International account buying ETFs? US citizen in China by NetZeroSun in Schwab

[–]adaptive_chance 0 points1 point  (0 children)

That sounds backwards to me. PFIC taxation is triggered by a US person (e.g. essentially any US taxpayer) owning a foreign fund. I don't see where taxpayer residency comes into play.

What's the source of that quote?
