I've already noticed that LVM has good performance compared to other solutions (like VMFS), but I tried to use ZFS exactly for scheduled replication :(
At this point ... I think that I've to migrate my tests to Ceph, discarding ZFS.
(anyway thank you for having shared your experience)
second round :|
Unfortunately "4k Block Size option" seems to work only with ZFS pools added on other disks beyond the first one (rpool/data).
I tried also to destroy and recreate "/rpool/data" (with 4k option), without success ... the VM located on it, keeps freezing during a heavy I/O.
Searching into the GUI, I found where to set this value (Datacenter > Storage > Add ZFS).
Now, after recreating the VM, Windows 10 seems to be more responsive during heavy load I/O.
I will continue my tests
Thanks for your support
Yes I installed ZFS over the installer on the GUI without changing anything (I'm a new user and I'm evaluating Proxmox for my virtualization needs).
I already seen the link above, but I don't understand how to set block size to 4k.
I have 16GB of RAM and VM has only 2GB, so I think...
This is my configuration:
SSD 250GB (ZFS with default parameters)
VM: Windows 10
When I do a copy inside the VM (for e.g. 5 Gigabyte from a NAS), it becomes almost unusable until the process is finished.
If I use LVM or Ceph on the same hardware, everything...
