It's a pitty ZoL does not support trim, but it is not a "must"! Sure trim is good, and having trim is better than not having, but "garbage collection" on modern SSDs can live without it (albeit not so effectively). Sometimes you can find that additional "user-level" over-provisioning might help...

I'm using both solutions and all I can say is: both HW-raid and SW-raid (ZFS) has advantages and disadvantages. I do not dare to say what is definitely better...

Never do combination of hardware and software raid (3, 4). Either hw-raid (you'd better not use ZFS then), or software raid...

/dev/zvol is directory, device node is elsewhere. But may I suggest you try to create it manually, with "mknod"? FYI in my installation: /dev/zvol is drwxr-xr-x root:root /dev/zvol/rpool is drwxr-xr-x root:root and in /dev/zvol/rpool there is link: lrwxrwxrwx root:root swap -> ../../zd0...

Try to repeat all those installer-commands manually, in debug-console (everything that starts with "#" in your install.log). Or at least try that "zpool create -f ..." command. Maybe some error shows. You might also try to increase that udevadm-timeout...

I think it depends on linux-kernel, if it supports your hardware (and to what extent). Sometimes not all features of new chipsets are supported. But if Debian can see it (you can try live-dvd), Proxmox should see it too...

There was problem with using disks which have been previously used somehow (and even cleaning with dd did not help), but I thought this had been fixed in PVE 5 "final" already...

A few more observations: 1. It is not possible to disable service from web-interface, only stop it (or start/restart). It means, after reboot it is again running. Could it be possible to add to "system" tab also "disable" (in addition to "start", "stop", "restat" that are already there)? 2. I...

Yes, I can agree. It just seems in this case that those other parts of systems do it less frequently. And log-server can be configured not to write every message separatelly, instead filling first predefined buffer (accepting the risk of loosing some logs in case of sudden system failure)...

There is no problem with writing status (if it is necessary), but doing it every 3-4 seconds seems to me to be overkill. Especially if host is configured as standalone (I suppose that "ha" has something to do with high availability; can I disable pve-ha-lrm/pve-ha-crm on stand-alone host?)...

I noticed this: when I start PVE 5.0, the process "pmxcfs" keeps writing something to disk all the time. Every 3-4 seconds there is a spike in writeops. This is going on and on forewer. According to wiki, "The Proxmox Cluster file system (“pmxcfs”) is a database-driven file system for...

With 400GB RAM at ~50% usage I wonder why you do not remove swap?

I'm not sure what you mean, but I opened tools->developer->webconsole, and tried to conect to web-interface. Console showed nothing. I waited a few minutes, then browser showed timeout. When I tried loading web-interface for the 2nd time, everything worked (in console I see "starting pve...

I have one strange problem with PVE 5.0: whenever I try to access web-interface, it gets stuck somewhere (I see just that rotating sign on browser-tab forever, nothing else). If I hit "reload", web-interface is suddenly properly shown in browser. Tested with clean FF & IE, all the same. What...

Logical solution would be to disable swap at installation. I tried it and set swap size to zero, yet PVE 5.0 installer created 2GB swap. Why? I have plenty of RAM, so why Proxmox is forcing me to have swap anyway?

Yes, zfs can live with 1-2GB arc if your disks were small and your disk reads/writes negligible. But for effectively caching 2TB drives, you need at least 4-8GB only for arc (and some ssd for slog/l2arc). With that zfs could do much better job. Try it one day, and you'll be surprised... If all...

Either add more RAM, or forget about ZFS. With just 16GB RAM (and 2TB disks!) you do not have enough memory for ARC and VMs...

You do not understand, or do not want to understand?

This is really strange: Im trying to install PVE 5.0, right now I'm on "Location and Time Zone selection" page. I selected country, i.e. Austria (strange, there is no drop-down menu, I have to start typing and then list of countries is shown). Time is automatically pre-selected as...

More exactly, it is udev-thing. Even distros without systemd use these new "predictable network interface names"...
