Hi Mary Ellen,
We were looking at this problem and are unsure what the problem is...
To rule out NFS as the root cause, could you create and share a test ZFS
file system without any ACLs to see if you can access the data from the
Linux client?
Let us know the result of your test.
Thanks,
Cindy

New to Solairs/ZFS and having a difficult time getting ZFS, NFS and ACLs
all working together, properly. Trying access/use zfs shared
filesystems on a linux client. When I access the dir/files on the linux
client, my permissions do not carry over, nor do the newly created
files, and I can not create new files/dirs. The permissions/owner on
the zfs share are set so the owner (mfitzpat) is allowed to do
everything, but permissions are not carrying over via NFS to the linux
client. I have googled/read and can not get it right. I think this
has something to do with NSF4, but I can not figure it out.
Any help appreciated

Running Solaris10 5/09 (u7) on a SunFire x4540 (hecate) with ZFS and zfs
shares automounted to Centos5 client (nona-man).
Running NIS on nona-man(Centos5) and hecate (zfs) is a client. All
works well.
I have created the following zfs filesystems to share and have sharenfs=on
hecate:/zp-ext/spartans/umass> zfs get sharenfs
zp-ext/spartans/umass sharenfs on inherited from
zp-ext/spartans
zp-ext/spartans/umass/mfitzpat sharenfs on inherited from
zp-ext/spartans
set up inheritance:
hecate:/zp-ext/spartans/umass> zfs set aclinherit=passthrough
zp-ext/spartans/umass
hecate:/zp-ext/spartans/umass> zfs set aclinherit=passthrough
zp-ext/spartans/umass/mfitzpat
hecate:/zp-ext/spartans/umass> zfs set aclmode=passthrough
zp-ext/spartans/umass
hecate:/zp-ext/spartans/umass> zfs set aclmode=passthrough
zp-ext/spartans/umass/mfitzpat
Set owner:group:

I can access, create/delete files/dirs on the zfs system and permissions
hold.

When I try to access the dir/files on the linux client, my permissions
do no carry over, nor do the newly created files, and I can not create
new files/dirs.
