For some reason, when i moved my hard drives to the new system (new mobo and controller) the way that the system is reading the serial numbers has changed slightly...

 

From: SHitachi_HDS723020BLA642MN1220F30WA3UD

To:    Hitachi_HDS723020BLA642_MN1220F30WA3UD

 

Is there a brute force method to change the super.dat for my new serial number format?  I think that is what i should change but i am not able to verify since the wiki is down

 

I am running unRaid 5.0 beta 13.

 

Thanks

short answer... yes

 

longer answer, in your version you must set a new disk configuration. 

Stop the arrray then use the

Utils->New Config

button.

 

Then, go back to the main page and assign the disks to their respective slots in the array. (if not already)

Do not start the array just yet, as a new parity calculation will occur if you do and since you know parity is good you can set it so it is not re-calculated, but just checked instead.

 

Type on the command line

/root/mdcmd set invalidslot 99

 

Then, back on the web-interface press the "Start" button.    (Do not "refresh the web-page until after the array has started or it will undo the set-invalidslot command.)

Sorry, just to double check, i will not lose any of the information on the array by doing it this way as long as i put all the disks back in the correct order... right?

correct.

As a precaution, you can make a copy of your config directory somewhere safe (on your PC perhaps) that way you can always revert back to the existing config.  You should be aware of how you originally partitioned the disks (MBR-unaligned, or 4k-aligned) just in case.  For each drive type

fdisk -lu /dev/sdX

to learn their partitioning, or, click on the "parity", "disk1", "disk2", etc... drive names on the main page to see how they are partitioned.

 

All the drive indicators should turn "blue" after using Utils-New Config and returning to the main page.

 

Whatever you do, (just in case) do not format any drives that show up as un-formatted.

worked great.  I am doing a parity check on the array anyway now since it has been about 6 months since the last check.

 

Thanks for the help
