Like.
ZVOLs also use CoW (like everything else on ZFS, which also makes it relatively slow) and new metadata especially never overwrites old metadata. It's always written separately and only when it's actually on the drive (synchronously) then the old... -
UdoB reacted to leesteken's post in the thread Storage setup? Separate OS and data drive? ZFS + Slog? with Like.
Good to hear, thanks for explaining this. 16G is good enough for a Proxmox installation or an SLOG or swap (since Proxmox does not support memory over-commit). Although people are not overly enthusiastic about adding an SLOG for getting better...

UdoB reacted to leesteken's post in the thread Storage setup? Separate OS and data drive? ZFS + Slog? with Like.
The 16GB Optane might be useful as a SLOG or a special device (but the redundancy must at least match the data redundancy). I fear that the 58GB and especially the 375GB might be hybrid drives with 2 PCIe lanes connected to a small Optane and...

UdoB replied to the thread Storage setup? Separate OS and data drive? ZFS + Slog?.That's easy: get two "Enterprise class" NVMe with PLP. (But prepare for a heart attack while looking up prices.) Then run everything on this single mirrored vdev - on ZFS of course. You asked for "best performance" - and personally I do always...

UdoB replied to the thread Cannot login with 2FA enabled.Time based six digits? The "usual problem" is to have a different time on the host and on the device calculating the current TOTP. Please verify both clocks are only apart a few seconds. The safe range is a single digit difference, 30 seconds...

Why? The whole point of this thread is, that rclone isn't relieable for this and thus not supported. Running PBS in a docker container is also not supported, so you are introducing two points of potential errors (although docker propably doesn't...

UdoB reacted to Johannes S's post in the thread How granular is QEMU Guest Agent's ability to report on RAM usage inside a Guest VM? with Like.
Setup a real monitoring system like zabbix, prometheus, checkmk or icinga in a dedicated vm or lxc and put the agent of your chosen monitoring tool inside your guests. Proxmox dashboards will never have the same features set and reliability.

UdoB reacted to Alfonsok's post in the thread TrueNAS SCALE plugin on PVE 9.2 (NVMe/TCP): two findings worth knowing, and a fork with the fixes with Like.
We have been running the TrueNAS storage plugin for Proxmox VE (github.com/truenas/truenas-proxmox-plugin) in production for months: three nodes on PVE 9.2.4, NVMe/TCP against TrueNAS SCALE 25.10, plus iSCSI for testing. Two of the things we hit...

UdoB reacted to leesteken's post in the thread Couldn't find any package by glob error while installing Linux hearers with Like.
A common issue is that third-party driver are not compatible with newer kernel versions. Maybe look at /var/lib/dkms/synosnap/0.12.10/build/make.log as the message suggest? This will not tell you much but it might help the third-party driver...

UdoB reacted to Impact's post in the thread [PVE 9] Question re: Swap Setup on Small RAM VM -- Any Downsides to Setting Swappiness to 1 to avoid small MiB swap I/O? with Like.
I exclusively use ZRAM in my VMs so I don't need to manage a SWAP partition/file and backups don't contain the SWAP content. On my node(s) I use ZSWAP if possible. Since you already have a SWAP device (can't tell what kind without swapon) you...

UdoB reacted to Bu66as's post in the thread File-Restore: Mount eines 9-TB-NTFS-Volumes schlägt fehl (ntfs3, ENOENT ohne Kernel-Meldung) – kleineres NTFS derselben VM funktioniert with Like.
Saubere Vorarbeit, mehr Eingrenzung geht kaum. Bei deinen Zahlen: 18874331135 Sektoren bei 8 Sektoren/Cluster sind ~2,36 Mrd. Cluster, also knapp über 2^31. Mit 4k-Clustern liegt diese Grenze genau bei 8 TiB, und dein C: ist mit ~26 Mio. Clustern...

UdoB reacted to cwt's post in the thread Any built-in method to export to a CSV or excel Spreadsheet the Summary Listing for each HOST or a overall DATACENTER Sumary? with Like.
For a cluster you can get all node resources with: pvesh get /cluster/resources --type node --output-format json An example for a csv export (package jq needed): pvesh get /cluster/resources --type node --output-format json | \ jq -r '...

UdoB reacted to delltech1's post in the thread [TUTORIAL] Why LVM-Thin Cannot Be Shared Storage in Proxmox with Like.
Thank you for raising the fencing concern. A few points should be made clear: This is an experimental community project. It is explicitly presented as a release candidate for disposable lab infrastructure and disposable data. It is not...

UdoB reacted to Bu66as's post in the thread Ist eine "Rewind"-Funktion über ZFS-Snapshots in Proxmox praktikabel? with Like.
Bei Sanoid kommt noch dazu: Snapshots, die du außerhalb von PVE anlegst, kennt PVE nicht. Wenn dann pvesr oder normale VM-Snapshots im Spiel sind, kracht das zusammen, und ein zfs rollback wirft alles weg was nach dem Ziel-Snapshot kam, inklusive...

Ja Guacamole ist cool, aber irgendwie auch eine "Pain" zu managen ;-) Ich bin auf keiner Weise verbandelt mit Kasm, aber meiner Meinung nach wäre es für OPs Usecase wirklich einen Blick wert. Den am Ende des Tages bietet es genau das was er...

UdoB replied to the thread Configure a Fibre Channel LUN as a directory in a cluster..In my $dayjob I have FC storage, very similar like yours (including multipath), coming from off-site. ( 3-2-1 ) I use that one as a secondary independent backup destination, as a directory storage to put vzdump-based backups on it. Limiting...

Well I found a way! Since now formally arm is supported I tried again. And this time I got it to work. Cloud flare tunnels would probably work @yankluf. I have been working on a writeup blog article. Have a look if you are curious...
