Hello,
I installed a new (virtual) PVE 8 instance and created a firewall config with the WebGUI
alias
a_intern -- 10.10.68.0/24
ip_set
s_intern -- a_intern
security group
g_intern -- ACCESS tcp +s_intern 22,8006
and assigned this group to vmbr0 in a firewall rule:

Hello,
could you please look at this enhancement again - we would really, really need this functionality.
We just dumped our central Ceph storage (not proxmox Ceph) because of performance and stability issues and switched back to DAS (direct attached storage) - NVMe SSDs and ZFS. With NVMe SSDs...
Yes - very good hint - 128k volblocksize makes a big difference !
I additionally run some fio test inside the VM - the 128k volblocksize fixes the problems on sequential IO (like the tar test above) but does not slow down random read/write tests.
the VM stays responsive during the tests
the...
I've already created a zvol with 4K volblocksize (8K is the default) - same results.
Additionally I run the test on the proxmox host directly
created a 4K zvol
mkfs.xfs
mounted
Running the test generated 500-700 IOPs on one HDD and a load of >40 on the proxmox host - like inside the VM
The...

What makes me puzzled is not HW RAID vs ZFS zvol - it's ZFS raw image (ZFS dataset hosting a raw image file) vs ZFS zvol.
The difference between ZFS raw image and ZFS zvol is way too big - for the same test a zvol generates 20x to 30x the number of IOPs - this quickly fills up even a SATA SSD...
Hello,
inside the proxmox GUI I've created a 4 member RAID10 HDD ZFS pool (4T SAS HDDs).
I placed a VM disk inside this pool and wanted to copy a big repo from a physical machine to the VM (SCSI disk, discard=on,iothread=1,cache=none)
source (physical machine):
tar -cpf - repo | mbuffer -s...
Hello,
I've created a zfs pool (zssd960) with the proxmox GUI
After creating some VMs I see the disks of the VMs created as ZFS zvols direct under the ZFS pool
the rpool contains a subvol - data - where the zvols are placed
should I create a subvol on my pool (zssd960) also?
is there an...
