Gal,

I haven't done this before. But you can be sure that if you need to use ext2/3 or XFS on top of it, then it is local.
In Linux it is actually the filesystem (not the storage device) that defines whether a file can be mmaped and provides the POSIX semantics.

If you really want to find someone that 'did it', why not try the DB mailing list? SVN is just another DB user, as far as I can tell. And it has a much larger user base.

Good luck.
Jan Evert

PS: be sure to let us know in the end what you found out and whether you succeeded! Always useful for others.

        Hi Jan,
  
Thanks for your reply. Interesting point about ext2/3, and yes
the server will probably be running say redhat 9 in that case it's
usually ext3 I believe.
  
Admitadly, I don't know much about iSCSI and I was hoping for someone
to tell me "yes I've done it and it works".
  
On the surface, it makes sense that iSCSI will work, since
it probably looks like a local device, but I was kinda hoping for
someone to give me that extra level of comfidence, since this is
going to host the future rnd devel. tree of the company ..
  
The documentation says that the restriction on filesystem comes from
the DB and the filesystem should implement
  
     - "Berkeley DB requires that the undelying filesystem implements strict POSIX
     locking semantics and more importantly, the ability to map files directoy into
     process memory"
  
So if iSCSI does the above I guess I'm OK, but I don't know that yet.
  
thanks - Gal.

        Gal,

        Isn't iSCSI simply a storage device (like a disk connected as SCSI)? In that case I'd say it counts as a local harddisk.

        If the server would be running Linux it would probably have ext2 or -3 or XFS as filesystem. Those are filesystems that always count as local.

Subject: Will subversion repository work over iSCSI

        Hi All,

        I'm trying to push subversion in my company and I'd realy
appreciate any help ..

        We're trying to evaluate subversion here but the IT manager is abit
worried that subversion works only over local disks since these are
usually not a part of the company backup scheme.

        He wants the repos. to sit on our NAS, which supports
iSCSI as well as NFS (I'm aware that the latter is not acceptable).

        So will subversion work over iSCSI ?

        We will probably take a low-cost linux x86 machine for the server (I plan
to allow access to repos. only via subversion server, no local access).

        Any help would be greatly appreciated !

        Thanks - Gal.
