Do I have to migrate the data out of unraid disks first?  Or do I just plug it onto the new motherboard?

 

I am prepared to reinstall unraid, if needed.

Just plug it in.  No need to migrate data from disk to disk.

 

If you are on a recent 5.0beta version, the drives will all be recognized by their serial numbers.  If on an older beta, or on the 4.7 version or prior you will need to use the disk assignment page to assign the disks to their respective logical slots in the array (the older versions matched drives by their disk controller port, and those ports will probably have changed on the new MB)

 

Therefore, as the very first step in the migration, make note of the drive serial numbers and their slots in the array.    Then stop the array, shut down, and swap in the new MB.  Worst case, you'll need to re-assign the drives to their respective slots in the array.

 

Note: if any drives shows up as unformatted, DO NOT FORMAT IT.  Seek assistance.

I have done this myself with unRAID 4.7, I just pulled the old motherboard, put in the new one, reconnected all the drives and (as Joe pointed out) remapped the drive locations and then all was fine.

Hello Joe L., vca,

 

Thanks for the reply.  Is what you mentioned true even if the new motherboard is totally of different chipset?  Do I need to reinstall unraid on the flash drive?

yes, it is true, regardless of chipset.

You do not need to re-install anything on the flash drive.

 

You do need to set the BIOS on the new motherboard to have the flash drive as the boot device.  That's it.

Thank you for the confirmation Joe L.

I hope this will work for me.  Sounds like it will.  I want to replace my mother board, memory, CPU, and use a SAS controller.  Only problem is I cannot first view the unRAID setup page because my server has crashed and will no longer boot.  I do however have an old syslog and some of the unRAID status OK emails from the add-ins.  Could I figure out the assignments using that info?

 

I have an unRaid 4.7 system that stopped working in June.  I couldn't spend any time on it because of work and now my son and daughter are asking for the server back.  Also, I need to get some of our valuable pictures off of the server some how.

 

The system had been working flawlessly for years.  All of a sudden it crashed and won't boot.  There was some kind of a popup about a database corruption and then the system shutdown and I cannot reboot.  Unfortunately, I don't have the syslog because it crashed and there was no opportunity to save it.  I do have earlier syslogs and I have the hourly status emails from the add-in so I think I can figure out which hard drive is assigned to which unRaid drive by serial number if I had to.  I believe the data is fine on the drives so I'm hoping for suggestions on how to bring the server back up?

 

It is an older server I built in 2008 with 15 disks plus a cache drive and a swap drive.  It's using an Abit AB9-Pro motherboard with two Rosewill RC-211 2 port SATA II PCI Express Host Controller Cards and an Adaptec 4 port SATA controller card. 

 

Thanks for any help -- I miss my unRaid server.

 

You may want to solve the original error before swapping all of that hardware. Database corruption error sounds like it might be an addin that has gone awry and not unRAID. I'd make a complete backup of the USB stick, remove all plugins, and then try to boot it.

 

If you're really paranoid remove the drives that have your most sensitive data, mount them in Linux R/O, and copy off the data. UnRAID uses a standard Linux file system format (ResierFS) and the data should be readable...

Thank you.  I will do as you suggest.  I will backup my USB stick.  Copy my go script to a new file name.  Replace it with the following go script.

And try to boot.  I’ll let you know how it turns out.  I really think it is a hardware issue but your suggestion makes a lot of sense. 

Thanks very much.

Thank you for your suggestion BLKMGK!  I never got to try your suggestion because it occurred to me that I wasn’t even getting into the boot screens for unRAID.  It would freeze on the IRQ screen and not proceed.  I had a port 80 code of 94 which means that the POST process was not completing all the way.  I searched some more and found this - the solution to my server’s problem — http://lime-technology.com/forum/index.php?topic=4772.msg45030#msg45030 .  My CMOS battery from 2008 finally died and my BIOS couldn’t recognize my hardware any longer.  I simply replaced the battery on my motherboard, cleared the CMOS using the motherboard jumper, and re-configured the BIOS to have AHCI protocol on SATA and Boot from USB.  Now my server is back up and doing a parity check.  So far, so good.  Thanks again.  Love unRAID!
