Drive Replacement

[TKMTech]

I am trying to replace a dead drive, however when I try to do this I keep getting "member disk required" even though I have selected the new disk. I am able to create a new pool with the disk I entered so the disk is visible to the system.

Do a Wipe on the new drive first.

da6 is the replacement disk, and truenas is running baremetal. The disk is attached via dell per710 SAS controller.

Try this in the CLI:

dd if=/dev/zero of=/dev/da6 bs=1m count=1
dd if=/dev/zero of=/dev/da6 bs=1m oseek=`diskinfo da6| awk '{print int($3 / (1024*1024)) - 4;}'`

I can add this drive possibly as a hot spare and let the system then add it to the pool? However this is a work around and not a solution to the problem.

IT mode or Raid ?

 

[Alecmascot]

da6 is the replacement disk,

No, what model exactly is it. The serial number is missing.

No, what model exactly is it. The serial number is missing.

It is a seagate EXOS 10TB. The rest of the drives are white label EXOS 10TB drives.

no RAID. I disabled this to allow TrueNas to manage the RAID

So it is NOT flashed to IT mode? This is pretty bad. Please refer to the article

What's all the noise about HBAs, and why can't I use a RAID controller?

1) An HBA is a Host Bus Adapter. This is a controller that allows SAS and SATA devices to be attached to, and communicate directly with, a server. RAID controllers typically aggregate several disks into a Virtual Disk abstraction of some sort...

which specifically applies to your H710 unless it has been crossflashed to IT mode.

So if I do this, will truenas lose it's raid configuration on the drives?

yes. You will need to restore from your backup.
