Does anyone know if the default NFS for Proxmox using an NFS server is synchronous or asynchronous?
Since default does not set ac or noac the mount is asynchronous.
That's great news! Vmware sets to synchronous, and using ZFS backed NFS, even with a fast ZIL performance is awful. I did some testing with Proxmox and performance was amazing and I was thinking maybe I was looking at the numbers wrong
Well, setting async for VM storage isn't good way...
That depends. In general I agree, but one might have no real choice. Depending on the setup, it might be perfectly safe...
As far as i know iscsi does asynchronous writes as well. So that makes me think doing asynchronous with NFS is just as sketchy as using vanilla iscsi.
