Like.
I'd either let PVE manage the ZFS pool and give OMV storage from that (ext4 inside) or pass a whole controller through to it. I'm not personally a fan of giving a guest a whole part of my hardware as it goes against my idea of a hypervisor. -
I think the OP is talking about MailGateway (not sure since his post doesn't say much about what he actually wants to achieve) not PVE. The recommendation is the same though: https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#chapter_pmgupgrade

mailq edit: Oh, and the command which I execute habitually: dmesg -T | tail This many times let me unexpectedly spot unusual events which colleagues or a monitoring system haven't noticed.

UdoB replied to the thread Significant IOPS Drop in Proxmox 9.1.9 VMs Compared to Other Hypervisors.Yes, that's my understanding too. Only when the (additional!) filesystem layer has an additional read-cache or an additional write-cache (lying about "finished writing your datablock") in any way, it may actually look faster. Disclaimer: with...

I wonder about the discrepancy between block- and file-based storage. I remember several reports, that block-storage actually perform äs better since it avoids the overhead of a filesystem.

This is just one of the reasons you shouldn't use ZFS on raw device mapped disks: https://www.truenas.com/community/resources/absolutely-must-virtualize-truenas-a-guide-to-not-completely-losing-your-data.212/

UdoB reacted to daanw's post in the thread Advice needed for Datacenter Cluster ZFS storage with diferent zpools on nodes. with Like.
You can change the rpool and dataset names after the installation is complete. Roughly; - Chang the name rpool and rpool/data in all config files. (find /etc -type f -exec grep -H 'rpool' {} \;) - Run proxmox-boot-tool refresh to update the...

UdoB replied to the thread Advice needed for Datacenter Cluster ZFS storage with diferent zpools on nodes..You are not the first one to stumble upon this problem, e.g: https://bugzilla.proxmox.com/show_bug.cgi?id=6174 , https://bugzilla.proxmox.com/show_bug.cgi?id=7200 No, I have no solution... :-(

UdoB reacted to leesteken's post in the thread Mixed 1-CPU + 2-CPU subscription purchase for 3-node cluster with Like.
As I understand it, you need to purchase three 1-socket subscriptions as each host uses a different key. You cannot share a 2-socket subscription over two hosts. Contact the Proxmox shop with purchase questions to be sure.

You can always submit a feature request, the best place for this would be bugzilla : https://bugzilla.proxmox.com/

UdoB reacted to Johannes S's post in the thread [SOLVED] Gegenseitige Sync Jobs - Dubletten? with Like.
Warum willst du überhaupt pushen? Für Backups gegen s3 ist das natürlich nötig, bei PBS muss dagegen der pushende PBS auf den anderen schreiben können, was der pull-sync vermeidet. Wenn du also nicht gerade unverschlüsselt Backup hast, die vor...

UdoB reacted to Falk R.'s post in the thread [SOLVED] Gegenseitige Sync Jobs - Dubletten? with Like.
Da du ja für beide Standorte verschiedene Namespaces nutzt, synct er eh nur benötigte Chunks der jeweils lokalen backups und wie vor mir geschrieben wurde, werden bereits vorhandene Chunks nie noch einmal übertragen.
-
Hi, ja, ist genau wie du vermutest. PBS checkt vor dem Sync, welche Snapshots bereits auf dem Ziel vorhanden sind, und überspringt sie. Der Rücklauf B→A würde daher quasi leer durchlaufen.

UdoB reacted to daanw's post in the thread RAIDZ2 with 6x 480GB SSD only 1.35TB usable total with Like.
The way COW works, the 2:2 parity data is still on the zpool after you 'move it out', and still being used to calculate the total space of the pool. You need to actually replace that data with 2:4 parity data so it calculates with that. 1.35TB...

But RAID5/6 probably does not give good performance (in terms of IOPS, which you need for multiple VMs trying to use the drives at the same time). I though I mentioned that in my post.
