Degraded Pool : Cannot offline drive assume dead

[lankster2k]

I have a degraded pool status and a disk I assume needs replacing.

But if I try to force OFFLINE the device in the Pool Status view it errors :

Error: Traceback (most recent call last):

I'm on Version: TrueNAS-12.0-RELEASE

From the missing serial number in the disk view I can see its not listed. I assume its da7 that missing as all the other numbers were sequential.

ada0 is where truenas is installed - all the others are for storage in one pool.

Can someone assist in resolving? I assume I can't offline it as its already dead - that would make sense. I just want to confirm next steps.

If i try to REPLACE the following comes up :

The top dialogue just has a dash.

Are there shell commands that would show if that disk is active but not visible to TrueNas Core?

Can i just replace it and then add to the existing pool ?

Many thanks

Replace is expecting to have a blank (burned in if you choose to do that) disk in order to replace the "failed" disk with.

That screenshot seems to indicate there are no such disks available.

I have the exact same issue.
Drive died. Replaced (could not offline, due to OP's exact stated error). Now I cannot offline NOR replace for the same reasons even though the underlying FreeBSD shows the device mounted.

The issue is that the middleware sucks.
To resolve from shell:

zpool offline poolname /dev/multipath/whatever
At this point, the new disk was still not available to use via Replace from the middleware. At least for me. Even though the underlying BSD (you can see this in "dmesg") mounts the drive as something like /dev/da123 the zpool doesn't bring it in for whatever reason so...

reboot
Even after this, for me, I then got "Error: [EZFS_NOENT] no such pool or dataset" when trying to Replace, again because the middleware sucks. So...

zpool replace poolname oldidhere /dev/multipath/whatever
Note that the oldidhere is what's displayed by "zpool status" as the bad disk.

You can monitor the resilver process with
zpool status
