I hadn't been very active with unraid for a while, pretty obvious from the version 4.2.1. A while back I think I was in a rush and tried to update to version 6 without reading the READ ME. I did make a backup of my flash drive. When it didn't boot I just shut it down and figured I'd diagnose the problem later, well know is later. I restored the backup of the flash drive back to the version 4.2.1 and tried to boot the server but I get a message "verifying data pool", and it just hangs there, and I have verified that the server is configured to boot from the flash drive.  What are my options so I don't loose my data. Any help is greatly appreciated.

 

By the way, I do know this is support for version 6, but I posted here because upgrading to version 6 might be an option.

You have a long road to traverse. 

 

First thing:  Do you know the serial numbers of the drives that were data drives, parity, and cache drive (if used or even available with 4.2.1).  Without knowing these you have to be very careful if you don't want to lose data.

 

Second thing:  Have you read this Wiki? 

http://lime-technology.com/wiki/index.php/Upgrading_to_UnRAID_v6

It contains a lot of information that you are going to need when you do the conversion. 

 

Third thing:  You are probably wondering why I am not providing you with any help in getting your earlier version working again.  I have been using unRAID for over five years now and I have never even run version 4.7!  I am not qualified to provide you with any help in this area.  I suspect that there are a lot of other folks in the same situation.  That is one of the penalties that you may have to pay when you adopt the idea "that if it ain't broke, don't fix it".  When it does break, there are very, very few folks who can help you fix it. 

 

We should be able to provide with assistance to get your data back and help you get version 6 running using the HD's from your current server but it will be a slow process.  The first thing will be for you to verify that your CPU and MB are both 64 bit compatible.  You will also need at least 1GB of RAM at an absolute minimum! 

 

Hi Frank, thanks for the quick response. Normally I always upgrade to keep thing up to date, but since I hadn't been using the server for a bit I got lazy, mistake #1, mistake #2 was trying to upgrade without doing my proper research. Luckily I did take a picture of the drive layout, so I do know the serial numbers and drive placement.

 

I'll tell you my server build and maybe you can tell me if I should upgrade anything and what I need to do first to safely switch to version 6. I believe both the motherboard and the processor are both 64 bit compatible. The processor is a Pentium D 840, the motherboard is a Gigabyte GA-EP35-DS3R and I have 4 gigs of ram. The power supply is a Seasonic 700w. 11 data drives and one parity, all SATA.

 

Best regards

Hello again Frank, 

Well, I'm up and running with version 6.3.3, all data intact and currently running a parity check. Everything went really smooth except I couldn't get the server to boot at first, I kept getting a failed to run syslinux.c32 error. I re-formatted the usb to FAT instead of FAT32 and that fixed it. Now its time to swap out some of my older/smaller drives.

 

Thanks again,

Gary T

Glad to hear that you got it running.  One thing that you will probably have to do is to run the 'New Permissions'  tool  (under 'Tools') to fix the file owners and permissions as root is not  longer permitted to access Shares.  It  is a one time thing...
