PVE 7.4 here. There's something wrong with my Windows guests. No matter the underlying hardware, I have very poor performance in I/O for write operations. Like, 1.3GB/s in read and about 100MB/s in write. I tested using both my Ceph storage and local SSDs.
I have latest VirtIO drivers...
This issue has been solved. This thread is for anybody having slow I/O performance and searching for keywords. The cause might be ZFS trimming the rpool. I’m running proxmox version 7.3-1 on a Supermicro A2SDi-8C+-HLN4F with HP SSD EX920 1TB for the rpool.
My proxmox node was unresponsive. VMs...
a while ago we set up a three node Proxmox cluster and as storage backend we use the built in ceph features.
After a while we noticed a strong decreasing of I/O Perfomance in the VMs when it comes to writes of small files.
Writing a single big file at once seems to perform quit...
I'm facing high a strangely high I/O delay.
I have 3 times A Dell Poweredge 720XD with (almost) the same configuration.
The main specs are that are the same over all three servers are:
- 26x 500gb SSDs in a ZFS pool (RaidZ3) ashift 12 with a block size of 256K
- 380GB of ram

I'm sure this question has been asked before, but I can't decide what would be best. More RAM, and additional L2ARC - and in that case which type?
Proxmox is currently running on a HP DL380 G9 with one PCI-E slot available, so I could get a card that supports NVMe and add around 250 GB fast...
I have installed proxmox 6.3 INTEL NUC10I7FNH (64GB RAM, 1 TB SSD) a week ago and added a Debian VM and it has been working fine. 3 days ago I added another Debian VM and then a Windows 10 VM. Ever since the guests have been halting and the host has been throwing Input/Output error to every...
I've got a HP DL380 G8 running with 2x300GB 15k SAS in RAID 1 and 4x300GB 15k SAS in RAID10. Controller has 1GB of cache, Write Cache is enabled, BBU is present. Controller status is ok.
I've just set it up (yes, raid resync is long done) and moved my VMs from my other server. LXC...
I have a Proxmox standalone installation and have high I/O when working in any instance running in raid ssd.

Wir haben einen neuen Proxmox Server da die anderen 4 im selben Cluster bald voll sind. Nun wollten wir einige wichtige Server die mehr Leistung brauchen migrieren.
Der erste Server war kein Problem. Die Migration verlief problemlos. Beim zweiten funktionierte ebenfalls alles...
i have some strange issue with my proxmox node server, the issue is that when i powerup a openvz container (small one 1gb memory 20gb hdd) the nodes just freaks out - means that loads goes 200+ i/o is 99% and this load/io is cused by kswapd* process.
