USB stick is deleted when ZFS pool is created

Please attach diagnostics when the problem happens.

Will diagnostics work without working Flash?

 

If the diags don't work copy the syslog somewhere else and post here, e.g.:

 

cp /var/log/syslog /mnt/disk1/syslog.txt

 

And deleted again. Is reproducible. 😏

I do see the flash drive is being wiped, not sure why though.

 

The pool you are trying to mount is degraded, missing a device, a device that is now a part of a different pool, maybe that is creating some confusion.

 

Let me try to see if I can duplicate, you are just starting the array, correct, not doing anything else?

 

Also please post a screenshot of main and the output of:

zpool import

before array start.

I know that a drive is missing.

 

However, there is no reason to delete the flash stick. Imagine that an HDD or SSD in your zfs pool is broken and then the unraid USB stick is also deleted. I have now created the stick again. Probably 15 times already.

 

I don't feel like having the stick deleted again. The error is there and it will affect other users, at the latest when a device in the pool breaks.

That's why I'm reporting it here as "Urgent". To have the error fixed and help before it affects others.

 

 

Ich erstelle den Pool neu mit zwei

Understandable, I was just trying to make it easier to reproduce, because I wasn't able at first, but I've now managed to do it, difference was the number of slots for the new pool.

 

Thanks for the report, it's a corner case, but still a bug.

 

 

 

P.S. as a workaround for now, if you need to import a degraded pool give it the number of lots it should have, that won't trigger the bug, e.g.:

 

 

This has been fixed on v6.12.10.
