zfs discuss - Nov 2010 - vidoe files residing on zfs used from cifs fail to work

I find that at least some kinds of video files when accessed on zfs
server from windows machines will not work.  In particular that seems
to hold for quicktime files.

When *.mov file reside on a windows host, and assuming your browser
has the right plugins, you can open them with either quicktime player
or firefox (which also uses the quicktime player).

But I find if the files are on a zfs server the same files fail to
play.

Is it a local phenomena or a common problem/

I''ve also had similar problems with *.avi contained files (not sure of
compressor).

I haven''t heard loud laments about this so hoping it might be something
on my end since it would really be a shame if I cannot do my video
work on a zfs share and so take advantage of snapshots while work is
underway.  Something like a versioning system can be gotten out of the
snapshots if need be.

Not for me, I''ve been sharing all forms of media via CIFS to windows 
clients for a couple of years or more.

We don''t have that problem, and we have roughly 25TB of QuickTime files
on
an OpenSolaris box shared over CIFS to mostly Mac clients.

Good news again.   Good to know it can work just as I hoped it would.

You say `mostly Mac'' so I guess some windows clients are involved as
well.  And no problems with them either?

Just to be sure of something here.

Are either or both of you sharing these files in the sense of storing
them on zfs and moving to whatever OS for usage or do you mean that
files are used in place... that is, the zfs fs is not just storing
files but the files are being used by other OSs in place? 

It sounds like maybe both situation would apply to either of you.

If that is true then any ideas where to start digging as to why I see
the problem.

I realize that will be OT here but maybe a suggestion of URL or a
pointer to a newsgroup where the topic would be more friendly?

In my case, all files are accessed (read and written) directly to and 
from the CIFS share.

What are the property settings on your dataset?
