    IsThisThingOn reacted to chrcoluk's post in the thread One zfs pool slows down all other zfs pools with Like Like.
    What is the outcome of 'zpool status' please, there is detail lacking here. Do all the pools have their own independent disks?

    IsThisThingOn replied to the thread PROXMOX Backup - By VPN.
    I simply base that on the number of lines of code. At least openvpn is more insecure, simply because it is a bloated beast. But since we are hopefully working with 2FA, API tokens and we only allow connections from the static /56 or /48 prefix...

    IsThisThingOn reacted to Johannes S's post in the thread PROXMOX Backup - By VPN with Like Like.
    PBS doesn't work with ssh though but with https (via Port 8007), ssh is only needed for administration on the command line. And imho it's a wide stretch to assume that wireguard or openvpn are more insecure than ssh, imho the security of...

    Just a heads up, not sure if this applies to you too. Today I setup a remote PBS and forgot to open up the new IPv6 WAN rule on the remote firewall. Instead of a "could not connect to remote" or something like that error, I got a "permission...

    IsThisThingOn reacted to sterzy's post in the thread [SOLVED] Does PBS make use of atime? with Like Like.
    Proxmox Backup Server needs at least relatime for the garbage collection to work correctly (see [1]). So yes, the atime property is needed, but for performance reasons only relatime is used (not standard atime). From man 7 zfsprops: [1]...

    IsThisThingOn posted the thread Why is 128k used for added ZFS storage? in Proxmox Backup: Installation and configuration.
    I could be very wrong, but this is how I understand file size / record size / compression in PBS: - Backups on the host are done in 4MB chunks. - With compression enabled by default, ZSTD might compress them a little bit. - With compression...

    IsThisThingOn posted the thread [SOLVED] Does PBS make use of atime? in Proxmox Backup: Installation and configuration.
    Does PBS actually make use of atime? Or is it just inherited because of ZFS upstream? TrueNAS disables atime by default for performance reasons.

    IsThisThingOn replied to the thread QCOW2 on ZFS, but over NFS?.
    That makes it even worse by introducing another abstraction layer. No. Why should that be the case? So you want to move of the storage from PVE to a ZFS box and access it over NFS? So then the no copy on write happens on your PVE host but you...

    Nutzt du kein LVM? Ansonsten funktioniert vielleicht eine offline Methode: https://pve.proxmox.com/wiki/Resize_disks#Online_for_Linux_Guests

    IsThisThingOn replied to the thread Sizing calculator.
    Based on your questions asked, and not even describing a clear performance goal, I would also recommend you a partner. Or you get a system that is on the save side, meaning having at least the RAM amount you have know, CPU performance you have...

    IsThisThingOn replied to the thread Sizing calculator.
    That is a long outdated and not very good to begin with rule. Just as the old and not very good rule "don't fill your pool over 80%". My problem with both rules is that they are way too general and ignoring the actual use case. For some use...

    thanks for the feedback! always nice to hear that users/customers are happy :) just fyi: if you have a subscription, you can enter it in your forum account under 'account details' and then you get a 'subscriber' badge here, so we (and others)...

    Thanks for your great support! Awesome how good proxmox support is even for the community subscription. I thought I knew how ARC works and that your new default is way, way too small. Turns out once again that you pro guys know what you are...

    IsThisThingOn reacted to dcsapak's post in the thread VM was shutdown for unknown reasons with Like Like.
    sadly SMART data is not really standardized and some vendors use offsets or different units or formats for the temperature. Better monitoring for the temperature can be done by loading the 'drivetemp' module with `modprobe drivetemp` and using...

    Haha, oh my gosh sorry, you are right. I just looked at the 16th and just assumed September, this has nothing to do with this shutdown :D Logs from where? Maybe I am not educated enough, but I did not see anything worthwhile in the event viewer.

    IsThisThingOn replied to the thread VM was shutdown for unknown reasons.
    Do I understand you correctly, that you also don't think it came form the GUI,API because it isn't in the PVE task list? Regarding Windows event viewer, it gets a little bit strange and I am a little bit confused what happened here. Looking...

    IsThisThingOn posted the thread VM was shutdown for unknown reasons in Proxmox VE: Installation and configuration.
    Normally I would not think much about a VM shutting down, but that VM has a GPO policy so there is no shutdown button. This made me curious to find out what caused the shutdown. Proxmox webGUI: Here I see nothing of interest in the task list...

    This isnt really a pve question. Also, I would strongly advise taking this opportunity to migrate your mail server to a currently supportable environment- mail is one of the most obvious places for external attack after all. Luckily for you...

    IsThisThingOn replied to the thread Write amplification for OS only drives, zfs vs btrfs.
    You are right, performance might also be a thing in a homelab. And this PDF proofs my point even further. While the Samsung SM863 is a "server grade SSD", it is almost 10 years old and gets outperformed in many metrics by basically all existing...
