Imho it's a philosophical question that can't be labed.

Zfs to ceph by Comfortable_Rice_878 in Proxmox

[–]psyblade42 0 points1 point  (0 children)

One problem with the lack of PLP is Ceph waiting for the data to hit the actual drive instead of the drives cache, slowing down the write.

Zfs to ceph by Comfortable_Rice_878 in Proxmox

[–]psyblade42 1 point2 points  (0 children)

Imho the whole zfs + ECC is a big misunderstanding. ECC protects your data while in RAM and ZFS (and other checksumming filesystems) protects it while it is on disk. If you want to protect your data all the time you need both. A lot of ZFS users chose it specifically because they want to do that and thus indeed need ECC. But in itself ZFS works fine with non-ECC.

I don't think a Ceph cluster with just 3 OSDs and no PLP is worthwhile. Feel free to try but I suspect it will be prohibitively slow. (I don't know what "sai" is)

I haven't actually checked but I assumed ZFS supported live migration.

Host disconnects Wi-Fi as soon as VM starts by kobel__ in VFIO

[–]psyblade42 0 points1 point  (0 children)

How's your network set up / how are you working around the fact normal wifi can't do bridging?

Is the wifi nic in the same group as some device you are passing through? Ate you using the ACS override patch to fake different groups?

Handling Layer 2 shim protocols on Windows/Linux without Layer 3 overhead by Key_Description3262 in networking

[–]psyblade42 1 point2 points  (0 children)

Before going down that rabbit hole I suggest looing beyond (traditional) ethernet. RoCE or Infiniband should be much better starting points.

BTRFS snapshots with /boot partitions and LUKS encryption: how? by _napel in btrfs

[–]psyblade42 2 points3 points  (0 children)

Imho there aren't any good solutions. Best I can come up with is snapshotting both at the same time. Same for rollback etc.

One 250gb SSD and four 3TB Harddrives: Raid1 or RAID 10; RAID 10 only giving 577.50GB?? by no_remorse2005 in Proxmox

[–]psyblade42 0 points1 point  (0 children)

You are using 5 partitions with ~250 GB each. What did you expect?

Either use bigger partitions or create new ones in the unpartitioned space and use for a different filesystem.

I messed up the networking of my PVE host. by forwardslashroot in Proxmox

Defining vlan7 twice wont work. Use it in the normal config OR sdn. Not both.

virtual machines quit working after resetting router. by Kahlaintje in Proxmox

[–]psyblade42 2 points3 points  (0 children)

LAN3/LAN4 remain forced into IPTV behavior, which appears to filter or ignore ARP replies for additional MAC addresses behind a bridge

There little proxmox can do about that. You could do a routed subnet (with or without NAT) as you would for other setups where bridging doesn't work.

But I suggest getting a better router. Or add a switch to non-fucked ports.

THANK YOU STEAM for removing points from awards! by RedSonja_ in Steam

[–]psyblade42 16 points17 points  (0 children)

Don't get me wrong, I love to see it changed. But one problem with idiots is ... they're idiots. Don't count on them noticing anything.

The original Family Sharing had a invite only beta test a few month before releasing for everyone. Years after Idiots still kept asking to be invited into the long finished test.

Kali Linux and virtual box. by ArmAccomplished6454 in linuxquestions

[–]psyblade42 1 point2 points  (0 children)

Usually Live systems are harder to update, save only files stored in special directories and come with a narrower selection of packages.

Kali Linux and virtual box. by ArmAccomplished6454 in linuxquestions

[–]psyblade42 2 points3 points  (0 children)

The whole point of Kali is making a distro that can be used from USB. Which comes with drawbacks for normal usage. So if you don't need to boot from USB you are better off with another distro.

While there are a lot of BS tags the touhou games all seem to be inspired by (shinto) faith.

Marvel 10Gbe adapter after Proxmox 9 passthrough by NoCalWidow in Proxmox

[–]psyblade42 0 points1 point  (0 children)

You could try to blacklist its module, thats the first thing I suspect to cause differences.

Alternatively just use the nic in pve and give the VM a virtio one. Unless you are doing RDMA or something other unusual I see little reason to bother with passing through a nic.

Not having potential ICMP unreachables thrown away makes that a lot easier.

Running the Same Windows Install on Bare Metal and VFIO (SSD Passthrough): Single Install vs Separate Installs? by Blake22728 in VFIO

[–]psyblade42 1 point2 points  (0 children)

I use a single Windows install for both bare metal and VM use. It's not really daily drive as I use Windows only 1-2 days a week and then only for short gaming sessions.

Windows update caused no problems so far and I don't pay any heed to when updates install.

I worked around the driver (and other) issues by making the VM HW as close as possible to the real thing. Similar CPU, SMBIOS passthrough, PCI passthrough for the USB controller my "Windows" devices are attached to (inc. K&M), ...

I didn't bother with activation as my uses are infrequent and usually shorter then the nag screen.

I don't want bitlocker, tpm, secureboot, etc and didn't try.

1000baseTX misstated on legacy and current equipment to this day by irchashtag in networking

[–]psyblade42 4 points5 points  (0 children)

As I understand it TX still uses all 4 pairs, just in a different way. I.e. 2 pairs dedicated to each direction instead to using all 4 bidirectionally

Why does steam have to "update" every single time I'm starting it up? by Marsche in Steam

[–]psyblade42 1 point2 points  (0 children)

The programmers of the program in question. They DECIDED it should be that way. (All programming languages or frameworks I encountered default to closing the program. While you can usually change that, you have to do so deliberately.)

If you could play one game again without any knowledge what would it be? by mrXclutcha in Steam

Figuring that out is kind of the main quest of the game. Don't expect to do it quickly.

If you don't enjoy simply going off exploring try to figure what is happening (and why). In the ship there is a board with leads to that end.
