IIsThisThingOn replied to the thread HPE ProLiant DL380 server. Proxmox installer crashes after 30 seconds.I would try another USB stick.

IIsThisThingOn replied to the thread Do you need to shutdown VMs to backup them with stop mode?.Ahh, so it is only there to know what it needs to backup, to get a backup from the shutdown state, without the changes that happened to the disk during the backup. So maybe on ZFS it would theoretically also be possible to create a snapshot and...

IIsThisThingOn replied to the thread Do you need to shutdown VMs to backup them with stop mode?.but apparently also in stop mode. As seen by my output logs from stop mode. Sure it might not get used or used in a differently way, but it seams like it at least gets created?

Like.
Please actually check your write amount before needlessly implementing things like that. -
IIsThisThingOn replied to the thread How to Reduce SSD Wearout in Proxmox?.Watch out when doing PBS backups with that setting. If I remember correctly, PBS makes use of that. To get back to your initial question "How to reduce wear out" the correct answer IMHO would be: Don't worry! Others here recommended PLP drives...

IIsThisThingOn replied to the thread Do you need to shutdown VMs to backup them with stop mode?.That is what I thought, but I am not sure if this is entirely correct. In the logs you can see this, no matter if the VM was running or not, when using stop mode: INFO: scsi0: dirty-bitmap status: created new So there is some dirty-bitmap that...

IIsThisThingOn reacted to vc45100116's post in the thread how to enable concurrent pbs backups? with Like.
That's all I needed to know, PBS doesn't do concurrent backups and that's fair and acceptable.
-
IIsThisThingOn replied to the thread how to enable concurrent pbs backups?.Someone else has to chime in. I simply assume it is not possible, since there is no option in the gui or cli or anything written in the docs about concurrent backups AFAIK. IO workers is, well about IO workers (webGUI shows me default of 16 for...

IIsThisThingOn posted the thread Do you need to shutdown VMs to backup them with stop mode? in Proxmox Backup: Installation and configuration.Do you need to shutdown VMs to backup them with stop mode? Or is it needlessly loosing uptime by doing so? Here is how I used to think it works: I thought it does not matter if the VM is running or not. In both cases the VM will be shutdown, a...
-
IIsThisThingOn replied to the thread how to enable concurrent pbs backups?.AFAIK that is not possible. That is about IO workers, not about how many VMs are backed up simultaneously. Why would you want to do multiple backups at the same time anyway? If you have a performance bottleneck, running multiple backups at the...

IIsThisThingOn replied to the thread Langsame 4k Performance in Windows 11 VM.Ist das immer noch RAIDZ1? Was bekommst du denn auf PVE direkt raus, wenn du PVE benchmarkst? Sowas in die Richtung: fio --ioengine=libaio --direct=1 --sync=1 --rw=write --bs=4K --numjobs=1 --iodepth=1 --runtime=60 --time_based --name seq_read...

IIsThisThingOn reacted to Khensu's post in the thread Langsame 4k Performance in Windows 11 VM with Like.
Ich würde dir vom umstellen auf vollblocksize=4k abraten. Bei RAIDZ1 mit ashift 12 (Default), würdest du nur 50% der Kapazität verwenden können. RAIDZ ist tricky und etwas komplizierter zu verstehen. Da kommt Padding mit ins Spiel. Bei 16K...

Hallo @Joe77, die CrystalDiskMark-Werte bestätigen das Problem — die sequentiellen Werte sind hervorragend, aber 4K Q1T1 mit ~35/28 MB/s ist für drei PM983 NVMe im Verbund deutlich zu wenig. Die Ursache ist, wie @cwt schon angedeutet hat, das...

IIsThisThingOn replied to the thread Whole disk backup every time on stopped VM.Like others already said, by default it reads everything. The money quote line is this one: 107: 2026-02-28 21:00:07 INFO: scsi0: dirty-bitmap status: created new Since the VM is not running and/or you have the stop backup mode, it can't make...

IIsThisThingOn replied to the thread Proxmox für 500-1000 VMs.Ohh, danke, das war mir nicht bewusst. Das auslesen und hashen der kompletten Disk. Habe ich eine 1TB disk und möchte ein inkrementelles Backup machen mit Windows Server Sicherung, TimeMachine oder ZFS send geschieht dies sehr schnell und ohne...

IWenn ich sowas lese stelle ich mir die Frage ist das WLAN „wlp0s20f3“? Wie hast du die Hardware im LAN mit Ethernet, WLAN oder GLAS? Bitte die Ausgabe von deinem Proxmox ip a und die Ausgabe also codeblock hier posten

IIsThisThingOn replied to the thread Proxmox für 500-1000 VMs.Inkrementell würde ich PBS nicht bezeichnen. Jedenfalls nicht was die Leute traditionell verstehen unter inkrementell (VSS oder ZFS send). Ja, den hash mit einer lokalen hashtable zu vergleichen spart einiges an Übertragung, aber wenn die VM...

IAlso ich würde in der Größe nicht mehr mit 25G beginnen sondern direkt auf 100G.

IIsThisThingOn reacted to Johannes S's post in the thread Storage for small clusters, any good solutions? with Like.
The point is that it's also often possible to do HA on the application level and might be even more relieable. For example for webhosting having multiple webserver vms (on different nodes) and before them a loadbalancer/reverse proxy like nginx...
