zfs discuss - Jul 2007 - Share and Remote mounting ZFS for anonyous ftp

Experts,

Sorry if this is a FAQ but I''m not on this alias.
Please reply directly to me.

I''m working on a project setting up a web portal that
will use 2 hosts for load balancing ftp''s. I wanted to
use ZFS to showcase it to our customer.

What I''ve been trying to setup is anonymous ftp to a host that
is sharing a ZFS file system. Anonymous ftp is configured and
does work on the 2 hosts I''m working with. But when I try to
create a common ftp mount point between the 2 hosts (load balancing)
I get permission errors or fchmown errors.

I was wondering if there is a setup/configuration issue or won''t ZFS
work with remote mounting and ftp.

Configuration:
SystemA sharing /export/ftp/incoming (zfs)
SystemB mounting SystemA:/export/ftp/incoming

Both hosts have the same permissions on the directories.
I''ve setup anonymous ftp on both systems with the ftpconfig.
Went through the steps of setting up a shared zfs file system:
zfs sharenfs=on portal/ftp-incoming
zfs set sharenfs=rw=SystemB.domain,root=SystemB.domain portal/ftp-incoming

Mounted the shared file system on SystemB:
mount SystemA:/export/ftp/incoming /export/ftp/incoming

I''ve setup /etc/ftpd/ftpaccess for upload to /export/ftp/incoming and
to change owner and permissions to a local user:
upload   /export/ftp   /incoming   yes   webadmin   www   0440   nodirs

Problem is that I will get errors when I try to upload a file. Errors are
either permission denied or a fchown error. I''ve changed ownership on
the
/export/ftp/incoming from root to webadmnin to ftp without success.

Need suggestions fast for this project is suppose to go live soon.

Thank you for your help,

Dale

All,

As a follow up on this issue. This was not a ZFS issue after all it was a
configuration issue which I''m still curious about.

I had changed ownership from root:sys on a directory that was going to 
collect
the anonymous downloads to a user that had the same UID and GID on both 
hosts
and permissions 777. I had also changed it to ftp and a known GID, which 
still
didn''t work.

To get the ZFS file system to upload from the remote host the UID:GID 
had to be
set to root:sys on both hosts.

root:sys /export
root:sys /export/ftp
root:sys /export/ftp/incoming  <--- this is my anonymous login 
repository for both hosts

I would like to thank all who had responded.

Dale
