visible in OF but the 'create new volume' tab has an entry for  a file system type, 
I guess you format it at this point? Is it possible to create a volume without 
formatting if you already have a volume with data on it? Perhaps I'm talking 
nonsense here, don't forget I'm new to this (& linux).
Please see my earlier post regarding this. You need to edit volumes.xml to bring the volumes under Openfiler management.

As I mentioned earlier, I would have thought you should be able to create new disks 
& volumes with an exported volume plugged into the controller shouldn't you?  
That volume should be left exported while I create the rest of the volumes on my 
system. That's what appears to be causing the problem.o
Maybe, never tried it.

A minor point here, the volume storage is 1.7TB but in Volume Group 
Management/View member PVs it shows as double that size - 3538.06GB.
Cool, I'll look into it.

If the metadata for a volume is lost or overwritten,

I was referring to Openfiler-specific metadata not the LVM metadata.

 does that mean the data is irretrievably lost (I know the importance of 
backups) or can it be recovered by any linux utilities? I'm still learning 
about linux and wondered if I stupidly/accidentally overwrite the metadata is 
there any way to recover what's on there.


An easy way to determine whether your data is still there is to mount the volume.

So for example:

VG=storage
LV=data

then do:

vgchange -ay
mkdir X
mount /dev/storage/data X
ls X

There's now functionality in the GUI that allows for backing up your metadata.


OK, so what you really need is the ability to access and manage the VG

"storage" and any LVs associated with it.

What I worry about however, is that your lvdisplay did not show any
LVs associated with the "storage" VG.

Do this:

pvscan
vgscan
vgchange -ay
lvdisplay (and look for LVs associated with "storage" VG)


Go to /opt/openfiler/etc/

edit volumes.xml

Make it look something like this:

<volumes>
<volume id="test" name="test" mountpoint="/mnt/data/test/" vg="data" fstype="ext3" incominguser="" incomingpassword="" outgoinguser="" outgoingpassword="" />
</volumes>

The above should be pretty self explanatory.

You'll need to edit your fstab and enter the relevant data to mount
the volume(s)

Then do:

mount -a


It does indeed make it impossible to get at data.
