Replacing HDD in ZFS on FreeNAS 8.2.0-RELEASE

[danb35]

I appear to have a failing hard drive in my RAIDZ1 array. I've seen instructions for replacing a drive under prior versions; are they still valid for 8.2, or does the GUI "Replace" button work reliably (and if so, how do I use it)? The Wiki doesn't seem to have any documentation on this subject.

Just replace the bad drive, let it re-silver, than detach the old bad drive.

The FreeNAS manual provides thorough instructions for replacing failed drives(or upgrading for that matter). The instructions are exactly the same as far as I know. The buttons might have moved slightly or something like that, but the basic theory is still the same.

Hi danb35,

I think this:

http://doc.freenas.org/index.php/Volumes#Replacing_a_Failed_Drive

is what you are looking for.

Sure enough--not sure how I missed that when I was looking at the wiki. I'll buy a new drive and see how it works. Thanks!

Replaced the drive over the weekend, and it worked fine. Only oddity now is that 'zpool status zfs1' returns a very long string for the device name of the new drive, unlike ada1 and ada2 for the other drives in the pool. Definitely not a big deal, though. Thanks again!

That would be the gptid vs devname. To match the device names with the corresponding gptid the following should be sufficient:

Code:

glabel status

If not there is the much longer:

Code:

glabel list
