charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hello, we are moving to Proxmox now and I would need some help from you. In the past, I have always used NFSv3, because in our KVM environment, we h= ad issues with NFSv4.1 and head fail-overs -> VMs got paused I think also VMware had such issues. Problem I think is that NFSv4.1 is sta= teful and on a head fail-over, this state got lost. I'm on 9.14.1. As NFSv3 is quite old and Proxmox is using a newer kernel, I wanted to ask,= if someone of you have experience with Proxmox and NFS volumes from NetApp= . Do you use special mount options? Is NFSv4.2 working fine with head fail-overs -> VMs are not pausing or don'= t even notice it? We have 25 Gbit network interfaces as a bond to our NetApp, are here any sp= ecial options to configure? Are you using on VM disks "cache=3Dnone" or something different? Unfortunately, Proxmox has not much experience with NetApp either, so that = I hope someone from you can help me here to create a good, fast and stable = setup. This is how a mount point looks like with default options from Proxmox and = NFSv3: nfs-root-01:/pve_DC_nfs_root_01 /mnt/pve/nfs-v3-root-01 nfs rw,relatime,ver= s=3D3,rsize=3D65536,wsize=3D65536,namlen=3D255,hard,proto=3Dtcp,timeo=3D600= ,retrans=3D2,sec=3Dsys,mountaddr=3D172.16.4.3,mountvers=3D3,mountport=3D635= ,mountproto=3Dudp,local_lock=3Dnone,addr=3D172.16.4.3 0 0 This is from our old virtualization oVirt: nfs-root-01:/oVirt_DC_nfs_root_01 /rhev/data-center/mnt/nfs-root-01:_oVirt_= _DC__nfs__root__01 nfs rw,relatime,vers=3D3,rsize=3D65536,wsize=3D65536,nam= len=3D255,soft,nolock,nosharecache,proto=3Dtcp,timeo=3D600,retrans=3D6,sec= =3Dsys,mountaddr=3D172.16.4.3,mountvers=3D3,mountport=3D635,mountproto=3Dud= p,local_lock=3Dall,addr=3D172.16.4.3 0 0 * oVirt was using soft, but this I think, I shouldn't use on Proxmox and inst= ead use hard. oVirt had a special watchdog for this.
