 That might be the best solution.

Unless they heavily modified how the filesystem works, you should be looking 
for a way to schedule a command on the next boot, before OS mounts the disks. 
I'm with Roland, sometimes paying extra saves money. This of course, 
depending on the importance of the data you lost, whether it's recreatable at 
all and how many man hours that would take.

Problem with today's modular software: they start with the modules
and never get to the software part.

It seems that SnapOS uses a modified UFS. See 
http://www.dtidata.com/resourcecenter/category/file-systems-explained/snap-server-file-systems/

I quote: 

SNAP Appliance used a proprietary Unix File System (UFS) handler in
 order to run there Network Attached Storage (NAS) product. This
 particular OS ran a Berkley Software Distribution (BSD) flavor of
 UFS. Although there are many similarities to the original file system,
 there are also enough changes to make file recovery extremely
 difficult.

So you could try putting it in a FreeBSD box, use dd to make an image of
the whole disk, and experiment on that image. But maybe you should
contact dtidata. They seem to know a lot about this appliance.

Alternatively, does the web interface provide a means to run a fsck?
That might be the best solution.

Hah, you're asking the right one, man. :-)

There are many good tools available from the ports, some of them can
even be used for diagnostics and recovery on UFS file systems. The
most famous one is The Sleuth Kit, another useful tool is magicrescue.

Try and see if they are helpful to you. Good luck!

file harvest

2008-11-10 Thread Jean-Paul Natola
Hi all,


I have a SNAP 4100 appliance that lost  2 directories, no backup ,  I sent it
out to a DR service and they have told me that all they can do is file
harvest, where I would get a list of files  such as file0001.xls file0002.xls
etc...

With no guarantee of what will come out, now we are a non-profit so 3k with
no guarantees is kind of hard to swallow-

Question is how can I, if it all possible, do a harvest of my own?

I believe the snap uses UFS 

TIA

Have you contacted http://www.overlandstorage.com? They list this
product as 'discontinued', complete with the 'SnapOS' that it runs. But
they might be able to help you.

 I believe the snap uses UFS 

A lot of UNIX systems use UFS, not just FreeBSD!

Log into the server with telnet of ssh. Check that it runs FreeBSD by
executing the command 'uname -a'. If so, run 'man fsck_ufs' and read the
manual page! (If the manual pages were not installed, you can read them
on the FreeBSD site instead). Otherwise read the 'fsck' manual page for
the OS in question. Run fsck_ufs on the filesystem in question.
Orphaned files and directories will be placed in a directory named
'lost+found'.

And start making backups!

Roland
