    ZFS SSD High IO Wait

    I would try again with "Enterprise Class SSDs" with PLP / "Power-Loss-Protection". ...and with mirrors, not a RaidZ2 - as this gives you only the IOPS of a single device. Of course SATA is massively slower than PCIe --> if possibly switch technology... Disclaimer: just random thoughts...

    [SOLVED] no ping during initramfs and so no dropbear-ssh

    Unfortunately I am not aware of built-in dropbear support in PVE. How did you install that? May be it helps to re-read that documentation...? (I mean it - you are outside of the usual PVE context and we just cannot know what you did!)

    Wrong size reported by CEPH

    At the top right, in your user menu, check "My Settings - Webinterface Settings - Dashboard Storages". Possibly the same storage is summed up more than once. Just guessing..., I am not using Ceph currently.

    CEPH rbd-mirroring

    I would ask that question (with as many details as in a compact way possible) via https://shop.proxmox.com/submitticket.php

    adding new devices to RAIDZ (new feature)

    I believe this is not implemented in the Gui (yet?). On commandline it works as intended. man zpool-attach tells you the syntax. This is a manipulation on the lowest level and failures may be fatal. Personally I do set a global checkpoint to have a way back to the previous state. See man...

    Help moving ZFS storage.

    Buy some USB-to-SATA adapters to use them temporarily for this task. They are cheap, five to ten Dollars/Euros each... Edit: that is probably not going to work for 3.5 inch harddisks, because of the required power...

    Replicate whole data center to another physical server

    PDM enters beta - it may possibly help migrating between non-clustered systems. (I did not test PDM yet...) https://pve.proxmox.com/wiki/Category:Proxmox_Datacenter_Manager Announcement 30 minutes ago: https://forum.proxmox.com/threads/proxmox-datacenter-manager-0-9-beta-released.171742/

    [TUTORIAL] Adding encrypted ZFS pool to Proxmox for VM storage + auto-unlock on boot

    That's of course the problem here. When I steal that computer I get the key for free. What attacking vector is it you are securing with this approach? The only situation I see is if the devices die so hard, that the build-in "erase"-function can not get triggered anymore and you want to send...

    Problem with WEB GUI

    Check and restart -if it is not "active (running)"- pveproxy: ~# systemctl status pveproxy.service ~# systemctl restart pveproxy.service ~# systemctl status pveproxy.service

    Is clustering production-ready on Proxmox VE 8.2.2?

    Yes, you are (or course) correct. Note that I do admit that although I am using ZFS exclusively - the few clusters I have are small. With that number of nodes ZFS-replication (over all nodes) would be a bad choice. And partial replication -let's say in two groups of four nodes- introduces...

    [SOLVED] Disable ZFS autosnapshot for a pool

    Each tool has it own benefits. But yes, I am using cv4pve for exactly that reason. While I am absolutely able to handle Desaster recovery with naked replicated snapshots the integration in the PVE logic and in the GUI is really convenient! The other important aspect is that it works...

    PBS integrity check: is the hash computed on PVE or on PBS?

    It is (first) calculated on PVE. Then this checksum is transmitted to PBS - only the checksum, no data. If a chunk with that checksum already exists on PBS then some references are updated to reflect this new backup. Only if that checksum is not already present on PBS then the data is...

    Guidance for Repositories - Enterprise -vs- No-Subscription

    Things like this can simply be tested: when I disable the debian sources and query the policy of a random (but known to be installed) package I get: ~# apt policy bash bash: Installed: 5.2.37-2+b5 Candidate: 5.2.37-2+b5 Version table: *** 5.2.37-2+b5 100 100 /var/lib/dpkg/status...

    swtpm at /usr/bin/swtpm does not support TPM 2

    I am not @fabian ;-) but I can show you this: My system is using non-subscription, everything updated. ~# pveversion pve-manager/9.0.6/49c767b70aeb6648 (running kernel: 6.14.11-1-pve) The swtpm binary comes from the corresponding package: ~# dpkg -S /usr/bin/swtpm swtpm: /usr/bin/swtpm...

    What's the expected content of "/etc/initramfs/post-update.d/systemd-boot"?

    Yeah, that the one instance I have with PVE + PBS installed in parallel. I will try to not take that node as an example-generator anymore, as I could not exclude extraordinary behavior. Glad you spotted it. That's why I usually copy-n-paste the actual command and the output :-) For the...

    What's the expected content of "/etc/initramfs/post-update.d/systemd-boot"?

    Just for completeness (it does not matter, "exit 0" is the relevant command), the "no-subscription" version is different: ~# dpkg -S /etc/initramfs/post-update.d/systemd-boot systemd-boot: /etc/initramfs/post-update.d/systemd-boot ~# apt policy systemd-boot systemd-boot: Installed...

    CIFS error 22

    No! "samba" is a meta package - it also includes the server part. Try to install the package "cifs-utils", it should deliver the command "mount.cifs"...

    FYI: ZFS pool SUSPENDED not recognized / handled - even with HA VMs starving

    Thanks for the hint; no I am in Germany. I looked at my large clock at the wall, it shows the right date. I read it wrong, for an unknown reason... And -of course- if you type wrong things willingly you can look at them as often as you want - it stays correct.

    FYI: ZFS pool SUSPENDED not recognized / handled - even with HA VMs starving

    Verbatim copy of https://bugzilla.proxmox.com/show_bug.cgi?id=6773 Short: a SUSPENDED ZFS pool is not recognized although all VMs stall and services are practically down. Long: after upgrade to Trixie 13.1 (pve-manager/9.0.6/49c767b70aeb6648 (running kernel: 6.14.11-1-pve)) on 08 Sept. 2025...

    node failure after 8 to 9 upgrade

    Try to follow https://pve.proxmox.com/wiki/Upgrade_from_8_to_9 carefully. As long as your specific system is not heavily modified it should lead to success. In your sources.list I can see at least one bookworm (should be trixie) and the fundamental "main" Debian source is... missing?
