Hi Michael!

/srv/fai/config x.x.x.x(async,rw,no_subtree_check)
/srv/fai/nfsroot x.x.x.x(async,ro,no_subtree_check,no_root_squash)

Hmm, no_root_squash is there... Does restarting nfs-kernel-server maybe help?


Problem found. I am not using nfs-kernel-server but nfs-user-server. That one does not seem to understand the option no_subtree_check which makes it stop parsing options there and thus obviously not parses the no_root_squash.

I wonder if this is a bug (in nfs-user-server) or a feature.

Nevertheless, changing to

/srv/fai/config x.x.x.x(async,rw)
/srv/fai/nfsroot x.x.x.x(async,ro,no_root_squash)

made the problem go away and I can not SSH into my install clients.

One problem less. Thank you very much for your help.

Regards,
Torsten
