Re: [zfs-discuss] libzfs API: sharenfs, sharesmb, shareiscsi, $custom ?

2009-08-17 Thread Ross
Hi Jorgen,

Does that software work to stream media to an xbox 360?  If so could I have a 
play with it?  It sounds ideal for my home server.

cheers,

Ross

It is llink, which was initially just HTTP streamer for 
Syabas/NetworkMediaTank, but I did just add UPnP, based on whtsup360 dumps.


http://lundman.net/wiki/index.php/Llink

You are welcome to try the latest development sources and test, but I 
believe the current state is that it shows up on 360, but does not browse.


However, llink just shares content, no transcoding. At least not yet.


Regarding the original question;
It seems that it is easy to add own attributes, I will peruse the  API 
documentation detailing how I would iterate file-systems looking for my 
attribute, since I would rather not system(zfs) hack it.

I cheated and simply use system() for the time being, but I will say 
that was rather nice and easy. Thank you Sun and OpenSolaris people.



llink.conf:
# If you use ZFS, you can auto-export any filesystem with a certain 
attribute set.

# For example: zfs set net.lundman:sharellink=on zpool1/media
ROOT|ZFS=net.lundman:sharellink|PATH=/usr/sbin/zfs


@root.c
debugf(  : looking for ZFS filesystems\n);
snprintf(buffer, sizeof(buffer), %s list -H -o mountpoint,%s,
 path, zfs);
spawn = lion_system(buffer, 0, LION_FLAG_FULFILL, zfs);
if (spawn) lion_set_handler(spawn, root_zfs_handler);



# zfs set net.lundman:sharellink=on zpool1/media

[zfs-discuss] libzfs API: sharenfs, sharesmb, shareiscsi, $custom ?

2009-08-16 Thread Jorgen Lundman


Hello list,

As the developer of software that exports data/shares like that of NFS 
and Samba. (HTTP/UPnP export, written in C) I am curious if the libzfs 
API is flexible enough for me to create my own file-system attributes, 
similar to that of sharenfs and obtain this information in my software.


Perhaps something in the lines of:

 zfs -o shareupnp=on zpool1/media

And I will modify my streamer software to do the necessary calls to 
obtain the file-systems set to export.


Or are there other suggestions to achieve similar results? I could 
mirror sharenfs but I was under the impression that the API is 
flexible. The ultimate goal is to move away from static paths listed in 
the config file.


Lund

Jorgen,

  zfs -o shareupnp=on zpool1/media

ZFS allows user-defined attributes to be set on datasets. So how about
something like that:

zfs set net.lundman:shareupnp=on rpool/export/ext

 And I will modify my streamer software to do the necessary calls to obtain
 the file-systems set to export.

 Or are there other suggestions to achieve similar results? I could mirror
 sharenfs but I was under the impression that the API is flexible. The
 ultimate goal is to move away from static paths listed in the config file.

That's a perfect use case for user-defined attributes
