Inherited OpenFiler 2.3

Good day, Experts!

I have recently inherited an OpenFiler system running v 2.3 (appears to be current) and wanted to tackle documenting the system from the top-down as best as possible.  Are there any tools or best practices freely available to breaking down the configuration to determine which volumes & targets are in use, utilization, etc?  It would appear that there are a vast number of volumes that are not "in use" and only two connected iSCSI connections established.  I want to be able to generate a picture of what the OpenFiler is actively servicing and ultimately put a plan together to better utilize the storage available to the unit.  I will be purchasing the Admin documentation this week to become intimately familiar with the service(s) but was hoping there was a quick and dirty how-to verify what it is currently configured, what is currently utilized and what connections/volumes are not in use that can be freed up and applied elsewhere.  I know this sounds a little vague but I have a lot of homework to do in order to be able to support this device and the servers that depend on it so any help/tips would be greatly appreciated.  Thanks!

Unfortunately there is no "one stop shop" for documenting it...
But the UI is fairly intuitive and fairly condensed...

If you choose the "Services" tab, you can see what services they have enabled.
Outside the iSCSI stuff, everything is shared from the "Shares" tab.

The LDAP service may be enabled if they are not connected to an Active Directory server or other LDAP server.  The onboard LDAP server is for local authentication of services like Samba (CIFS/SMB), NFS, FTP, etc.

I use OpenFiler quite a bit in production... so feel free to ask.
The OpenFiler Community Forums are also very good.  http://forums.openfiler.com/index.php

Thanks!

Thanks I kind of figured that would be the case.  If I can get these couple of questions answered I think that should be enough to get started with diving into the manual.  Funny that the admin guide needs to be purchased ;)

Distro Release: OpenFiler NSA 2.3
GUI Version: r1634-1-1

This box has been up 680 days and no one knows anything about it other than the credentials I was given to login and the hardware that it lives on.

I have two "Volume Groups" (P800 & P400) on the "Volumes" tab of the webui:

P800 lists 5 Volume Names with iSCSI FS types.  Of these 5 volumes only the first one is marked "In Use" and the other 4 have links to delete them in the UI.  P400 lists 2 Volume Names both iSCSI FS types.  Both of these are marked "In Use".

Q1:  Would my assumption be right that the ones that are not explicitly "in use" are truly are not used anywhere?  I should find a way to mount these somewhere if they are not in use to verify what is on them but I won't get that far ahead on this.

Q2:  These all appear to be used as logical drives to other servers; neither have LUNs mapped.  I see 6 iSCSI targets (iqn.xxxxxxxxx addresses) setup and 3 block devices.  Is there any easy way that I can find out where these iSCSI targets are mounted either by dns name or IP address from the webgui or shell?  I want to avoid logging into every server (there are a bunch in this datacenter) and fumbling through he iSCSI initiator on each one?  It looks like there is only one NIC with two IPs bound to it (eth0 and eth0:1) but oddly enough the box has four NICs.

I am familiar with iSCSI SANs and some of the terminology but it has really been a long time since I've played and I've not ever worked with OpenFiler before.  The only documentation that is available is pretty much limited to "Here is the IP address to the web interface and the credentials. Congrats you own it!".

Thanks for pointing me in the right direction.  I found the two iscsi targets are logical drives attached to two servers and going to try and figure out where these other 4 LUNs are pointed to.  I think they are storage for the vmware servers but I don't see them mounted.  Will dig some more with the manual but I may be back in a few days with more questions ;)
No trouble.

Best of luck...  and let me know if there is anything else I can do.

-Cheers, Peter.
