Disks from OpenFiler
Hello everyone,
I have an OpenFiler NAS box which I'm getting rid of and will replace with a TKL fileserver appliance.
The Openfiler box has 2 x 1.5 TB drives making up one drive using LVM where my TV shows sit.
Was wondering - what's the likelihood of plugging these straight in to the new TKL box and having them recognised?
The two physical disks make up a volume group with a single XFS volume on top which takes up the entire LVM disk space. The volume then has a few SMB shares in it.
Theres actually 3 volume groups like this on my openfiler box - one for movies, and one for a backup of my music collection, and they're all set up pretty much the same way.
Was hoping that I didn't have to do a) lose data in the transition or b) buy disks to set it all up and then have left over disks after i've migrated everything.
Cheers,
Smoe
Couldn't reply so I've Edited:
Yes you can plug them in and have them recognised*
I followed this http://tldp.org/HOWTO/LVM-HOWTO/recipemovevgtonewsys.html and it worked sweet. I didn't actually deactivate and export as I had some problems along the way - but i'll be blowing the old system away anyway. i'm not sure if there is any long term implications for the new system from me not deactivating and exporting properly.
*Unless you have a drive failure and lose your Movies Volume like I did.
My intention has been to get to the disks with a raw Ubuntu build and connect to the NAS drives via USB. XFS, as far as I have found, is only mountable by Linux (again, "as far as a I have found").. The upside to your post is that if my NAS was also LVM expanded it would mean the Raid was really just a "drive stack" which hopefully means they both have good data still.
The problem with what you are wanting to do is that I am not sure if TKL will mount a USB addressed drive. I know that VMWare won't. You would need to do a local install of TKL FileServer or TKL DomainController to find out. No harm, that I can see, in trying.
On my side I want to get to the Data then move it so it is an issue of "getting to it" then moving it. Fundamentally I think this is what you want to do also, but you should have the advantage of having access now. That said, take the advantage and move it if you have enough space now to do so. Once done you have a few Drives you can use as you wish (or sell as a NAS on Craigslist).
my 2 cents anyway.

but then I get to the end of your post and it is Solved! Good work.
How did you attach them to your system (USB or SATA direct)? What TKL build did you attach the drives to? Would seem a great solution. This NAS issue has been more than a frustration on my side (the drives are sitting in a ziplock beside me infact) but I will cross my fingers about a solution here.
