RolandK replied to the thread Proxmox Backup Server 4.1 released!.not sure if this is a result of the upgrade and how it looked before - but is this normal/intentional that size and encryption staatus for client.log.blob is not shown and that both blob files are not downloadable ? when unencrypted, they can be...

We're pleased to announce the release of Proxmox Backup Server 4.1. This version is based on Debian 13.2 (“Trixie”), uses Linux kernel 6.17.2-1 as the new stable default, and comes with ZFS 2.3.4 for reliable, enterprise-grade storage and...

No, we do not belittle this at all, and we do not delay this for time reason, the current system with having an ESP on every mirror device in addition of being able to recreate it is simply safe and redundant enough for the practical cases that...
-
RolandK replied to the thread MDRAID & O_DIRECT.yes, raid won't make backup obsolete. but from my admin perspective, it would be logical consequence to regularly check/scrub 100% of your system disks and not only 99% (i.e. 100% minus boot-part minus efi-part) , even if it would be possible to...
-
In general, it would be also good to note that the ESP itself is not really stateful and can be rebuilt from scratch relatively easily, e.g. using a PVE ISO's debug shell to do so. After all there are mainly the kernel and initrd's located on...

RolandK replied to the thread MDRAID & O_DIRECT.>afaik, i/o errors typically happen on read, not on write. addon note for this: https://www.enterprisestorageforum.com/hardware/drive-reliability-studies/ "The authors found that final read errors (read errors after multiple retries) are about...
-
RolandK replied to the thread MDRAID & O_DIRECT.yes, you are right, chances ar low, but i'm not not sure if we should really call it "over engineered" to check boot env for disk issues and to have "zfs|btrfs scrub" equivalent for bootenv. for all those who worry, here are some ideas how check...
-
RolandK replied to the thread MDRAID & O_DIRECT.yes, but while zfs is getting regular scrub, silent bitrot could indeed happen on partition1+2 on system which is rarely getting touched/updated. such issue will hit you when you don't expect it. chances are low indeed, but the sectors of...
-
We explicitly mirror the UEFI partitions outside of ZFS though. And not noticing with many months of uptime means one did not apply any updates for the same period of time, as else IO errors on setting up a new kernel there would get noticed, and...

RolandK replied to the thread MDRAID & O_DIRECT.good and valid point. would you like to open a bugticket for this @emunt6 ?

RolandK replied to the thread MDRAID & O_DIRECT.this is also affected. https://bugzilla.kernel.org/show_bug.cgi?id=99171#c24

RolandK replied to the thread New Windows VM Startup Recovery.it seems newly created qcow2 on lvm do not initialize the storage with zero but assume the storage is all zero. so you provide the same data to the qcow2 on re-adding which was there before. try deleting the windows vm and before recreating...

RolandK replied to the thread proxmox 7.0 (failed to prepare EFI).clearing nvram via setting jumper on mainboard also solved this problem for me on dell r620

RolandK replied to the thread [TUTORIAL] Understanding QCOW2 Risks with QEMU cache=none in Proxmox.ouch. Wow, what a great writeup !!! thanks for making/sharing it ! will re-read tomorrow in depth.
-
RolandK replied to the thread QCOW2 on ZFS, but over NFS?.>So with a local ZFS, and VM RAW disks, you can make use of the native ZFS snapshot feature. Which is (unlike QCOW I believe) instant. yes, but without fs-freeze from the guest agent and thus most likely having worse consistency

RolandK replied to the thread Fehler mit Docker Container nach Linux update.>Ob nun eine VM besser ist oder nicht muss/darf/kann jeder für sich selbst entscheiden. entscheiden können sie es schon. aber bewerten können sie es nicht, weil die meisten leider nur irgendein tutorial abarbeiten, in dem von den...
