Strange behaviour creating container on NFS share

[rocknrollnerd]

Hello,

I'm trying to set up test cluster installation. For this purpose I've got two Proxmox VMs and a FreeNAS VM which are in my hardware Proxmox. There's an NFS share in FreeNAS. Looks like share's permissions are OK - I can mount it to my Ubuntu with write privilege. I've set 777 in ZFS dataset permissions and mapped all users to root (just for testing purpose). Hovewer, here's the Proxmox log:

Nov 27 10:12:17 proxmox2 pvedaemon[3292]: <root@pam> starting task  UPID:proxmox2:00005455:005EBAA5:50B459C1:vzcreate:100:root@pam:

First of all, creating a container with 500Mb volume takes about 10 min, is it supposed to be that slow? Second, the warning in bold confuses me: when I try to run this df command by ssh it shows correct output and gets no warning and no timeout.
Thanks.

Similarly. Backs up 20 GB of 80 and writes to the log such messages:
pvestatd[1643]: WARNING: command 'df -P -B 1 /mnt/pve/files-backup' failed: got timeout
