IDE Parity Disc Not Functioning?

Featured Replies

I just added the last drive to my unRAID setup, a 1tb IDE drive. I've assigned it as the parity disc, but it refuses to change from the blue dot to the green dot, signifying that it is not being used. What can I do? Are IDE drives not supported? I'm a little bit nervous as much of the data on the machine is not backed up, and would like to get the parity drive working ASAP.

 

Thanks in advance!

IDE drives are supported.  (Better be, because my array is mostly IDE)

 

First, where did you ever find a 1TB IDE drive?  I did not know they existed.

 

If it is a "blue" dot, did you "Start" the array? (by pressing "Start")

 

Post a syslog.  Odds are it is something simple.  Once you start the array the parity drive turns "orange"  (I think) while parity is calculated on the entire array.  This will take many hours (from 4 to over 16, depending on the disks involved)

Today we had a power failure in the area. After I rebooted the machine, I now have the two options "start" and "restore." They state:

 

"Start will bring the array on-line and start Parity-Sync.

Restore will initialize the stored array configuration; all drives will appear as New, but data disk contents are not affected."

 

What should I do? I have data that's not backed up on the array.

Do you have any disks with a "red" indicator?  If you do, don't even think about pressing "restore"

 

Never use the button labeled as "restore" as it immediately invalidates your parity disk and sets a new disk configuration based on the existing assigned and working drives.  It is actually a "Set Initial Disk Configuration" button.

 

Always use the "Start" button unless you are removing a drive from the array and do not intend to immediately replace it and do not want the data on it.    There's an exception to this rule, but it is used only when all your disks are good, or when you want to force a specific disk to be invalidated and rebuilt.  It involves a command line command issued between pressing "restore" and "start"

Thing is, I don't think the parity disc was doing anything before the reboot. If there's nothing in the reboot, will starting it this way delete the data on the other discs to match the empty parity?

 

And none of the discs have red indicators. The parity disc has a blue indicator, and the two data discs both have green indicators.

I think that in your particular case pressing the 'restore' button won't hurt anything, since you don't have any parity to be thrown away in the first place.  Still, there is no reason to press that button.

 

Press 'start'.  As Joe L. said, always press 'start'.  Never press 'restore' unless one of the hero members on these forums specifically tells you to do so, since it is only useful in a few rare scenarios.

And Rajahal is a hero member if you haven't noticed.  ;D

 

 

:o  News to me!  Guess that must have just happened when I passed 500 posts.
