ZFS changed the default size of the arc cache from 50% to 95% of system memory in 2.3, see https://github.com/openzfs/zfs/issues/17052

Proxmox Backup Server 4.0 released!

@Amodin ,
This does not result in performance issues for other processes.
ZFS takes 95% of unused RAM. If your system needs that RAM for anything else, the ARC cache will shrink so your system can do other things.
Thanks, it's good to know. Like I said, it's never done that with my bare metal server, and to see it now all of a sudden not be the 'norm' I believe was still worth mentioning. That's a significant change from 'what it was' to 'what it's supposed to do', when it should have been doing that the entire time.
Definitely worth mentioning.
While more ARC cache is always better, my understanding is that Proxmox's dev team policy is to track the ZFS defaults. The default upstream in the OpenZFS 2.3 release was changed to use 95% of available RAM for ARC, so it changed in PBS (and presumably PVE).
On new installs of PVE the ARC cache is still limited to 10% of RAM ( max eight GB ) according to the manual:
That part mentioning the default for new installs is missing in PBS manual ( see: https://pbs.proxmox.com/docs/sysadmin.html#limit-zfs-memory-usage ) which makes sense overall: For a virtualization host you need the memory for the VMs and cobtainers and want to avoid the OOM killer. A backup server is basically a kind of file/database server whose performance will profit from the ZFS ARC cache.
Please note that the PVE/PBS manual doesn't mention the new ZFS defaults, guess I will file a bug report

That was the old default for PVE 8/ZFS 2.2.
I'm not sure what PVE 9 does yet, but I observed PBS 3 taking and holding 50 percent of available RAM for ARC regularly.
I’ve seen this same discussion elsewhere for PVE also…if the ARC defaults changed it would be helpful to update the documentation.
I need a bit of help with the upgrade. I'm following the directions at https://pbs.proxmox.com/wiki/Upgrade_from_3_to_4 . Specifically, I got a bit turned around on changing the repos over at https://pbs.proxmox.com/wiki/Upgrade_from_3_to_4#Update_the_Configured_APT_Repositories .
I ran through the instructions, but I'm getting odd output from the GUI. It could just be that the GUI is complaining that since I've updated the repos, there's no valid way to update PBS 3 anymore, but I wanted to double-check that I've done this right.
I'm using the no-subscription repos.
Here's what I've already done, per the Wiki.
I changed over all the repos to Trixie with this command:
After that, I added the new enterprise repo, just so it would be there if I ever get a support subscription.
At this point, apt update failed out with an error because I was unauthorized to access the enterprise repos, not having a subscription, so I deactivated the enterprise repo in the GUI.
I then added the no-subscription repo:
So, now, I think I'm there. Here's what my 3 source files look like:
The apt policy looks correct:
And apt update wants to grab about 330+ new packages. So, I think I've configured everything, but that warning in the GUI is still a concern.
pve3to4 seems to be happy.
Thoughts? Am I good to go?
EDIT: That worked.

You peaked my interest so I created a test VM with two virtual disks (both 100GB), four vCPUs and 24 GB of RAM. I installed both PBS4 and PVE9 on a ZFS mirror out of both discs. The PBS install ended up with using 50% of available RAM for the ARC cache as described in the PBS documentation:
The PVE9 install however ended up in using 10% of the available memory for ARC cache like written in the doc:
The values in /etc/modprobe.d in both installs reflected the 10%/50% rule from the doc too. So in the end the change of ZFS default behaviour doesn't matter on new installs of PVE or PBS since their installers already limit the ARC caches limit to a smaller default than 95%. I still think that it would be a good idea to mention it in the documentation so people upgrading from older systems or installed PBS/PVE on a regular Debian system knows about this.
I will write a bug report now
Edit: Bug reports are done, for reference:

Not sure when or how that happened. It could have been before the upgrade from PBS 3.

Thanks, @Neobin ! It's a bit overwhelming keeping up with some of the little details. I probably should have waited another few days.Afaict, the patch is not applied yet.
I assume a simple apt remove is enough? No strange flags necessary?

Wanted to update this from my end of things, @Johannes S & @SteveITS .
I've (somehow) got no zfs.conf in my /etc/modprobe.d/ directory on my PBS 4 install (upgraded from PBS 3).
I'm not sure why, and don't necessarily think it's the upgrade's fault, but in any case, ZFS 2.3 defaults seem to be controlling.
After a backup that ran overnight, I'm seeing the expected ZFS 2.3 ARC behavior, with 95 percent of RAM in use. I never saw it using more than half my RAM in PBS 3, so this is a welcome change.
I'm still not used to looking at the in-GUI ZFS statistics, so here's htop's view of ZFS ARC.
Did a succesfull upgrade with 8GB free hdd space. Just to let you know.
Hi,
? Without this, it won't detect Trixie as allowed. You can check in
are you sure you had the latest version of the
proxmox-widget-toolkit installed before the upgrade and reloaded the UI:

proxmox-widget-toolkit (4.3.13) bookworm; urgency=medium

Hi,
thanks for the report, typos have been fixed!
You're most welcome.
The odd output I saw in the GUI fixed itself after I finished the upgrade per the instructions and rebooted the system. All is well now; no errors or warnings in the update GUI at all (aside from the usual warning about a lack of subscription).
I thought I had upgraded PBS 3 until I was on the latest point release. Odd.
The
pbs3to4 tool didn't warn me about anything before or during the install while I was switching the repos around.Everything's working great now, though.
I didn't read through all of this, but the oddity I had updating had to do with the enterprise repo kicking in for some reason and the disconnect from terminal, which stopped the update packages. I had to rem out the enterprise repos then update again and it worked. If I left the enterprise repos enabled, PBS wouldn't update, lol.I need a bit of help with the upgrade. I'm following the directions at https://pbs.proxmox.com/wiki/Upgrade_from_3_to_4 . Specifically, I got a bit turned around on changing the repos over at https://pbs.proxmox.com/wiki/Upgrade_from_3_to_4#Update_the_Configured_APT_Repositories .
I ran through the instructions, but I'm getting odd output from the GUI. It could just be that the GUI is complaining that since I've updated the repos, there's no valid way to update PBS 3 anymore, but I wanted to double-check that I've done this right.
View attachment 89209I'm using the no-subscription repos.
Here's what I've already done, per the Wiki.
I changed over all the repos to Trixie with this command:
sed -i 's/bookworm/trixie/g' /etc/apt/sources.list
After that, I added the new enterprise repo, just so it would be there if I ever get a support subscription.

At this point, apt update failed out with an error because I was unauthorized to access the enterprise repos, not having a subscription, so I deactivated the enterprise repo in the GUI.
I then added the no-subscription repo:

And apt update wants to grab about 330+ new packages. So, I think I've configured everything, but that warning in the GUI is still a concern.
pve3to4 seems to be happy.

Thoughts? Am I good to go?
EDIT: That worked.
I did actually mention the enterprise repos in my longwinded post there.
I disabled the enterprise repo in the GUI (on the repository page) before I started doing the update process, but didn't mention that explicitly. (You can see the "disabled" tag in my config files.)
I'd recommend doing that before starting the process if you don't have a subscription just to make things simpler.
I still converted the enterprise repo config over to the new deb822 format, just so it would be in the format PBS expects. The old format might break in the future.
