[SOLVED] Preclearing a drive without mounting it?

Featured Replies

Hi everyone,

 

Okay so maybe i'm taking this the wrong way around - i want to add an old Samsung 1TB HD104UJ to my array. I'm using Simple Features, so when i stop the array, i'm able to see the new drive in the Device Status Screen. When i select it to include it in my array, i get a blue "new disk, not in array" dot. So far, so good, i guess.

 

The text mentions "Start will record the new disk information and bring the expanded array on-line. All new disks which have not been factory-erased will be cleared first, etc etc", but when i check the "Yes, I want to do this" tickbox and click on start, nothing happens. The array remains stopped, the new disk isn't being cleared.

 

I've tried to preclear using a telnet session, but all i have is the following:

 

Sorry: /dev/hde does not exist as a block device

Clearing will NOT be performed

 

edit: If i remove the drive from the array in the GUI, i can start the array just fine.

 

Is there something wrong with the drive itself?

 

Thanks for your support!

I think the first piece of advice you get here is to attach your syslog for better analysis. I think you might want to also try running SMART tests on the drive. That's the best place to start.

Best of luck!

Okay, so here's my syslog. Does it looks like unRAID is trying to load specific drivers for the new drive but can't manage to do so?

 

edit: and here's the SMART test for the new drive.

smart.txt

syslog.txt

Sorry: /dev/hde does not exist as a block device

Clearing will NOT be performed

 

 

You might try running preclear on /dev/sde... instead of /hde

Okay, i think i got things mixed up when checking the preclear topic:

 

...To invoke this script you simply list the name of a disk you wish cleared as an argument to the command, as in this example:

cd /boot

preclear_disk.sh /dev/hdk

...

 

Anyway, preclearing has started now, thanks :)

Glad you figured it out. I added a line or two on that page you linked to to make it more clear for the next person.

Cheers, Joe! Preclearing is 59% complete now, hope this will help getting the drive operational in the array.
