Hi, i'm using unraid 6.1.3. Recently i have a disk with a few read/write errors (but not redballed) and i'm trying to replace with another drive.

 

The old disk was a Seagate ST3000DM001-1CH166 (i'd mounted in a 'new' ad-hoc unraid server (5.0.6) and it says it's 2930265476 KB big), the new disk is a Toshiba DT01ACA300. My main unraid server says it's 2,930,265,476 KB. I cannot see any difference.

The new disk was precleared with 4k alignment without errors or any other issues.

 

When i tried to start my server to rebuild the new drive the server says: "Stopped. Replacement disk is too small" and next to the start button says "The replacement disk must be as big or bigger than the original."

 

I really don't understand what's happening.

Any help will be appreciated. I'm attaching my complete syslog (after a reboot) if it's needed.

 

Thanks in advance.

sorry for the many messages, i'm trying things i found in other posts.

 

hdparm -D for that drive says it has it enabled. the motherboard i'd use to preclear the drive was a gigabyte, i remember i'd disable it but who knows, maybe i'd reset cmos and i dont remember it.

 

There's a way to reformat it with hpa disabled without preclearing it again?  it took many hours (almost 30) and i dont want to leave the array unprotected that time.

 

thanks again

 

Preclear is not needed or used for a replacement disk, only for adding a new drive slot to an already protected array. It's still a good idea for a new drive because of the thorough testing though.

 

All you need to do is remove the HPA, and it should allow you to rebuild just fine, no need to preclear or format. The format will transfer from the drive you are replacing.

Thanks Jonathanm, i'd removed the HPA thingy with a hdparm -N command i'd found in the forum and now it's rebuilding fine.

 

 

edit:

 

It's my first disk replacement. it seems it's rebuilding it but also it says its unformatted. Do i need to format it or i just need to wait for the rebuild?
