RE: [Samba] sam-fs and samba (copy while staging / timeout)

2007-08-06 Thread Flanders, Dean
 
Hello,  

Thanks, that certainly seems to be a step in the right direction.  I see
that if the tape is already mounted, and not doing something else, it
seems to work reproducibly.  If the tape is not mounted (and this is a
VTL) or it is busy, then samba does not seem to occasionally pickup the
stream when it starts to stage the file.

Any further guidance or help would greatly appreciated!

Thanks,

Dean

You might want to try 'aio read size = 1', given that you have compiled
Samba with aio support.

[Samba] sam-fs and samba (copy while staging / timeout)

2007-08-05 Thread Flanders, Dean

Hello all,
 
I know about the patch from Tobias Oetiker to samba that helps with the
handling of offline files by putting a little clock on them, etc.  I
also know about samnet, which we are testing.  However, I have noticed
another issue with samba and sam-fs integration, that is the file does
not start copying from samba to the client until the file is completely
staged (increasing the copy time).  This is a problem if a person is
copying large file, this can take awhile and then timeout on the Windows
client.
 
Ironically if I copy the file with cp on the Solaris box to the standard
file system, I see the file copying as it is being staged.  I can even
NFS mount another Solaris box, and I see the file getting larger as I
copy to the NFS share.
 
I spoke with someone from Sun Germany, and they stated that some
functionality is being added into samba 3.0.26 to better integrate with
sam-fs, but I am not sure if that is relevant.
 
So my questions are:
- Can I prevent this timeout error (without modifying users registry
settings)?
- Can I get samba to start copying the file while it is being staged?
 
Any help is appreciated as we just implemented the system and this issue
could be a show stopper.
 
Thanks!
 
Dean
