Paritity drive not the largest capacity

Featured Replies

I've been playing around with the unRAID free version before I take the final plunge, but noticed this when configuring 3 disks.

 

I have hard disks as follows.

 

Disk1  WD15EARS 1,500,290 MB

Disk2  WD15EARS 1,500,301 MB

Disk3  WD640EADS       640,000 MB

 

I assumed both disk1 and disk2 were identical when setting up the parity drive, but unRAID quite correctly reports that disk1 is not the largest, and on looking I realize disk2 is, so started over.

 

I know the obvious answer is 'yes, this is the expected behaviour' ...but is it?

 

 

Do you have a Gigabyte motherboard? If so, you may be experiencing the HPA issue.

No, it one of these.

I've had some fun and games with the WD EARS drives, so it might have something to do with that, I'm know RMA the disks.

You do not need to RMA the disk, but instead just remove the HPA which apparently exists.  So far, every manufacturer of disks has had exactly the same size, therefore your disk probably should be too.

 

hdparm -N /dev/sdX

will typically tell the story. Or, attach a syslog.

I really don't think that the alignment issue changes the size of the disks.  But maybe I'm wrong.

 

I would guess HPA also.  Have you ever used the drives with a Gigabyte motherboard at any point in the past?  Doesn't matter if it was with unRAID or not.

Rajahal - very good point, and one I over looked, yes they were used in Gigabyte motherboard when I first got them and then subsequently ran WDAlign, and then my woes began! :(

 

I've just shipped the drives back, I'm done with them...when I get the replacements they will be going straight into unRAID...and jumpered!
