Mounting / dumping .etfs file   
Hi there,

I have a .etfs file that I'm trying to get at the contents of, but none of the utilities I've found seem able to do this
.  Am I missing the magic flag to etfsctl or fs-etfs-ram that will allow me to (ideally) mount the filesystem under QNX 
or Linux, or just dump out the files it contains?  I've tried dumpifs (it fails), and dumpefs just locks up at 100% CPU 
usage - is there another tool I should try?

Alternatively, if I could get at the ETFS source code I could figure it out for myself, but I keep getting access denied
 no matter which repository I try to checkout.  So far I've tried 
http://community.qnx.com/svn/repos/filesystems/trunk
http://community.qnx.com/svn/repos/coreos_pub/trunk
http://community.qnx.com/svn/repos/core_networking/trunk
all using the same credentials I'm logged in with here, but I can't get access.  

How can I dump out the contents of an .etfs file, or how do I get at the relevant source to write my own utility?

Thanks!

AW: Mounting / dumping .etfs file   
if you manage to get access you'll find dumpefs within the filesystems project
http://community.qnx.com/integration/viewvc/viewvc.cgi/trunk/utils/d/dumpefs/?root=filesystems&system=exsy1001

have you already confirmed the new access policies?

Re: AW: Mounting / dumping .etfs file   
Not sure what you mean by "confirmed the new access policies" - clearly I have a working account on foundry27 but the 
link you mentioned didn't work, it just redirected me to the homepage with an error at the top of the page:

Warning: array_key_exists(): The first argument should be either a string or an integer in /www/web_app/htdocs/monitor/
ping.php on line 134

My understanding was that with an account here I should be able to checkout most of the source code, including that for 
ETFS?


So dumpefs should be able to extract from a .etfs file?  I did try that and it locked at 100% CPU (tried from the SDP 
LiveCD, from QNX installed in VirtualBox, and natively on Ubuntu 10.04 x64).  Is there some other way to wield dumpefs 
that's not documented, or does it normally take an hour or more to dump an 85Mb filesystem?

Thanks!

RE: AW: Mounting / dumping .etfs file   
Dumpefs is for EFS files (FFFSv3, aka devf).  There is no equivalent for
ETFS.  The only way to extract data from an ETFS filesystem image, is to
burn the image to your target, mount it with fs-etfs, and copy out the
files.   Alternatively, if you have enough RAM, you can try fs-etfs-ram
to mount your image.
