Import stripe pool with failed drive.

[paradoxiom]

I created a raidz1 pool out of random drives to hold data for a move and one of them failed during it, I only got about 60% off it before it kept I/O faulting and disabling in TrueNAS completely.

I have since exported the pool.

I am trying to load it a few more times and see if I can get anything off it, but my system won't even boot up with the bad drive plugged in now - it just hangs somewhere around where it's checking disks etc, I left it for 45minutes and nothing.

If I could import the pool, could I try 'replacing' the bad drive with the same drive, or what can I do here?

The working drives in the pool:

The faulty one is a 4TB BarraCuda also.

Going off your screenshots, you made a stripe, not a RAIDZ - there is no parity, and ZFS can't import it unless all drives are present.

Right yes, I thought raidz1 was stripe so I was using them interchangably, I know there's no parity- so impossible to import without all drives present?

Right then, how do I go about getting my systems like, bootup-log file or something? I'll go shut down, plug the bad drive in, start up, etc etc.

Correct

It may be that you can't.

With a failing/failed disk in a striped pool, you have no options left to recover.

What you may be able to try (with no guarantees of any success) is to use dd to copy all the blocks off the "bad" disk onto another blank/new "good" one and then use that disk instead... but if the critical blocks are already unreadable to ZFS, then dd probably isn't a miracle cure either.

Thanks, I just wiped the drives and tossed the bad one, it was just media anyway.
