autofs NFSv4 problem with SCALE..?

[kim.bjoern]

Very excited with the SCALE release - looks very promising.

Currently testing as VM with a few basic NFS shares, I can't connect macOS autofs clients to share:

Code:

macOS Monterey client w. nfs.client.mount.options = vers=4,resvport

xch@10client0 ~ % showmount -e 172.16.100.14
showmount: Cannot retrieve info from host: 172.16.100.14: RPC failed:: RPC: Program/version mismatch; low version = 3, high version = 3

xch@10client0 ~ % ls -la /net/172.16.100.14 
ls: /net/172.16.100.14: Input/output error

Linux client works fine:

Code:

Debian 11 VM


xfl@r320-esxi-deb-22:~$ /usr/sbin/showmount -e 172.16.100.14
Export list for 172.16.100.14:
/mnt/SSD-148GB *
xfl@r320-esxi-deb-22:~$ ls -la /net/172.16.100.14
total 0
drwxr-xr-x 3 root root 0 Feb 25 11:43 .
drwxr-xr-x 3 root root 0 Feb 25 11:43 ..
drwxr-xr-x 3 root root 0 Feb 25 11:43 mnt
xfl@r320-esxi-deb-22:~$

MacOS works fine with a TrueNAS CORE server:

Code:

xch@10client0 ~ % showmount -e 172.16.100.221
Exports list on 172.16.100.221:
/mnt/vd-24G                         Everyone
xch@10client0 ~ % ls -la /net/172.16.100.221
total 6
dr-xr-xr-x  2 root  wheel  1 Feb 25 11:47 .
dr-xr-xr-x  3 root  wheel  2 Feb 25 08:25 ..
dr-xr-xr-x  2 root  wheel  1 Feb 25 11:47 mnt
xch@10client0 ~ %

Any ideas to fix - or debug..?

Could it be that the NFS service hasn't had NFSv4 enabled?

Seems your mapping is asking for it and the error seems to be saying max version is 3.

The default for the service is 4 not enabled.

Thanks @sretalla - but no.

NFSv4 is on, and the unix client connects to v4.x:

Code:

xfl@r320-esxi-deb-22:~$ /usr/sbin/showmount -e 172.16.100.14
Export list for 172.16.100.14:
/mnt/SSD-148GB *

drwxr-xr-x 3 root root 0 Feb 25 13:07 ..
drwxr-xr-x 4 root root 4 Feb 25 12:08 SSD-148GB
xfl@r320-esxi-deb-22:~$ /usr/sbin/nfsstat -m
/net/172.16.100.14/mnt/SSD-148GB from 172.16.100.14:/mnt/SSD-148GB

...and the MacOS client can connect to NFSv4 services (on a Debian 11):
