[zfs-discuss] cp: Operation not supported

Hi All,
We have set up a zpool on OpenSolaris 2008.11, but have difficulties copying
files with special chars in the name when the name is encoded in ISO8859-15.
When the name is in UTF8 we don''t have this problem. We get
"Operation not supported".
We want to copy the files with their name in ISO8859-15 encoding and do not want
to convert them to UTF8, because we think this will cause it problems further
down the road: The filesystem will be used as a network share (CIFS and NFS) for
windows and linux clients. The clients may not all properly support UTF8 at the
moment. So we''d like to avoid having to convert to UTF8 at this moment.

How can we copy files with an ISO8859-encoded name?

To demonstrate the problem:
# /usr/bin/cp ISO8859-K?ln.url /datapool/appl
cp: cannot create /datapool/appl/ISO8859-K?ln.url: Operation not supported
# /usr/bin/cp UTF8-K?ln.txt /datapool/appl/
#

What is the output from:

	zfs get utf8only datapool/appl

?

Hi Tim,
Thanks for having a look.
The ''utf8only'' setting is set to off.

Important bit of additional information:
We only seem to have this problem when copying to a zfs filesystem with the
casesensitivity=mixed property. We need this because the filesystem will
eventually be shared over NFS and CIFS.

I attached a file with the relevant zfs properties of the filesystem that has
the problem.
See zfs-prop.txt. Notice that utf8only is set to off.

My locale is set to en_US.ISO8859-15 when doing the copy, but that
doesn''t seem to change anything. I tried with en_US.UTF-8 as well with
the same result.

A truss on the failed can be found in truss-ENOTSUP.txt.
Notice the \xf6 in the filename of the stat64, which gives an
"ENOTSUP".

When we take an the UTF-8 name, the stat64 succeeds just fine. A truss of this
can be found in truss-OK.txt

Cheers,
Kristof/

Your detailed information was very helpful.  I have reproduced the 
problem on my own machine.  I will need to consult with our i18n folks 
on whether the problem is within zfs or one of their routines we are 
calling.

Hi Tim,
That''s splendid!

In case other people want to reproduce the issue themselves, here is how.
In attach is a tar which contains the 2 files (UTF8 and ISO8859) like the ones I
used in my first post to demonstrate the problem. Here are the instructions to
reproduce the issue:

Create a zfs filesystem with casesensitivity set to mixed and create one without
this setting.
Unpack the tar outside the pool and try to copy both the files from the tar on
to the zfs fileystem. One (UTF8) will work fine, the other will not.
# zfs create -o casesensitivity=mixed mypool/mixed
# zfs create mypool/normal
# cp UTF8-K?ln.txt /mypool/mixed/
# cp ISO8859-K?ln.txt /mypool/mixed/
cp: cannot stat `/mypool/mixed/ISO8859-K\366ln.txt'': Operation not
supported
# cp UTF8-K?ln.txt /mypool/normal/
# cp ISO8859-K?ln.txt /mypool/normal/
#

I filed

6783995 file creation sometimes failing within a zfs where 
casesensitivity=mixed

a short while ago.  I believe I already have a fix:

chinook:~/bugs/nonutf[1016] ls
ISO8859-K?ln.txt*  UTF8-K?ln.txt     koeln.tar
chinook:~/bugs/nonutf[1016] zfs get casesensitivity tp/timh/mix
NAME         PROPERTY         VALUE        SOURCE
tp/timh/mix  casesensitivity  mixed        -
chinook:~/bugs/nonutf[1017] cp UTF8-K\303\266ln.txt /tp/timh/mix
chinook:~/bugs/nonutf[1019] cp ISO8859-K\366ln.txt /tp/timh/mix
chinook:~/bugs/nonutf[1021] ls /tp/timh/mix
ISO8859-K?ln.txt*  UTF8-K?ln.txt

Still will need some folks to look at the change, though.
