I want to set up a new PVE environment and I´m not sure about the correct caching configuration.
I´m using the Adaptec ASR-71605 hardware RAID controller (RAID 1 and 2x SSD) with an integrated BBU and 1 GB of Cache. What is the best configuration in my case?
If I understand...
This is our installation:
- 3 Supermicro servers (https://www.supermicro.com/en/products/chassis/2U/825/SC825TQ-R720LPB)
- Each server has two 4TB Western Digital Red HDD disks.
- We use Ceph for which we have a 10G fiber optic network with a cisco switch.
We are new with proxmox/ceph...
Hello, I have a server with 5 sata disks, one SSD (128GB) and four HDD (2x2TB and 2x4TB).
I've installed proxmox 7.1 in the SSD.
I want to create two zfs pools (mirrored) one with two hard disks of 2TB and another with two disks of 4TB.
In the installation SSD disk I've created two partitions...
Hi there all,
I've tried to research on that subject although came empty net.
How would VMs that are running on NFS storage behaves in case of "momentary" storage loss?
I'm trying to figure indeed if Proxmox would buffer IOPS for some times before dead'ing paths.
I bet the safest would be to...
So I recently bought a dell power edge r720 server with 6, 4tb hard drives, 2 500 gb ssds, a hba raid card, 192 gb of ram and I added two pci e name 500gb nvme drives. I set up the 6 4tb drives in raid 10 and installed Proxmox on them and now want to set up the two ssd's as caching, but also set...
It would be great if the storage api/module allows to create special, log and cache devices for ZFS pools.
It is all fine doing that by hand but since HDDs will be with us for quiet a while it would be useful to have that available to avoid human error.
Also the storage API should allow to...
I'm a little confused with the documentation. The BTRFS page says
BTRFS will honor the O_DIRECT flag when opening files, meaning VMs should not use cache mode none, otherwise there will be checksum errors. which I understand to mean set the disk cache to anything other than none.
I just installed my Proxmox server.
I have a strange phenomenon. The installation is brand new, I have no VMs started and I have constant ram usage at 18Go.
Would this be normal behavior with ZFS using available ram to cache?
If so, is it quite disturbing because we do not know how to...
I am always continuing my tests and still need some advice.
My configuration is as follows:
1 128GB SDD (for Boot)
4 x 1TB HDD (for RAIDZ2)
1 x 500GB HDD (for internal backup)
1 port SATA free for a second 128GB SDD or a second 500GB HDD
The memory is 16GB and the users who will use it are 3...
I will set up a Proxmox backup server to backup our Proxmox clusters. There are total 9 nodes (6 in one and 3 nodes in one). There are approximately 40 VM and they are using 10TB disk space.
I will set up maybe 6 SAS 18TB spinning disks for this and now my question:
How big should the...
We've upgraded our PVE cluster of ndoes from 5.4 to 6.2 few weeks ago, we also upgraded our ZFS pool to the version 0.8.4. We also added an iSCSI storage (FreeNAS) which hosts now most of the storage.
I'm now seeing that the ZFS cache is like eating a little bit too much of RAM (this is...
ich habe das Problem das meine KVM VMs im RAM voll laufen.
Ich allokiere z.B. 4GB RAM und setze 2GB RAM als Ballooning ein.
Nach kurzer Zeit sagen wir mal X Stunden ist der RAM bei 3,6GB (laut Proxmox) gefüllt. Auf der Console kann ich gut erkennen das vom wirklichen RAM nur...
Since there are many members here that have quite some experience and knowledge with ZFS, not the only that I`m trying to find the best/optimal setup for my ZFS setup; but also want to have some tests and information in 1 place rather than scattered around in different threads, posts and...
ich bin ein Proxmox Neuling und plane derzeit das Aufsetzen meines Heimservers! Bislang hab ich hier einen Server laufen, auf dem Openmediavault läuft.
Folgende Dienste soll der Server bereitstellen:
- NAS-Funktionalität (SMB und NFS Freigaben)
- iOBroker für...
With colleagues, we have been using Proxmox VE for a long time. We want to implement Hyper-Converged Infrastructure (HCI).
I read about caching modes in the official documentation
I would like to hear an authoritative opinion. What caching mode...
I have added 1000 OVSIntPort to my proxmox node.
After rebooting i get the following message: linux route cache is full consider increasing sysctl net.ipv[4|6].route.max_size
Since then I also have a problems connecting via ssh to my VMs from public IP (dnat set up in...
