Hello Community
I have truneas core 12.0-U5.1
I have installed 6*6TB hardrives
my pool is showing degraded and this is what it shows on the pool status can someone please explain to me what it actually means and how to remove it from degraded state.
any help would be highly appreciated.
In the image below ada5 is showing online under RAIDZ1 → SPARE but it shows UNAVIL under spare (small letter at the end) why is that?
Also my total pool is 21.1 TB which mean its utilizing only 4 Disk where as I have 6 disk installed.
I understand that as its a raidz1 one hard disk is going to be parity but what about the 6th hard drive? If I have an extra spare hard drive as shown in SPARE would I be able to replace this spare with my failed drive?
The issue is I only have 6 SATA port on my PC and as per my understanding if I want to replace a drive I need to add the new drive then resilver and then take out the faulty drive. But I don’t have an extra port for that so if its possible to use the spare to resilver then I can take out the faulty drive and then add the new one as spare again.
I hope this makes sense. Really appreciate any help in this.
Thank you
The spare has kicked in to replace a failing drive, so it is “unavailble” as spare right now.
What follows requires human intervention and human decision: Investigate what happened and the health of the drives.
Here, ada1 looks bad: Check SMART reports, and initiate a long test if needed. If it is defective, the best course of action is to remove ada1 and turn the former spare into a permanent member.
You may have gone 6-wide raidz2 at creation rather than 5-wide raidz1, that would have been safer.
Hi @etorix
Thank you for your prompt reply
I have initiated the manual scan test in the meantime can you please guide me on how to turn the former spare into a permanent member?
also, I have a new 6TB hard drive that I recently purchased.
If i currently shutdown my NAS and swap out the faulty drive with the new drive. Will it work or will it delete my pool and data?
Click on the three-dot menu of the drive you want to remove.
As for the new drive, I’d suggest to burn it in and then add it as the new spare.
