Degraded Volume

[ck17]

I have a degraded disk on a volume.
Unfortunately the disk that is failing, was added to a existing volume, bot was not integrated into the raid, but is added as stripe

It looks like this:
WD-16 (Volume);
stripe
da1p2 (disk that is failing)
raidz1-0
ada1p2
...
ada5p2

how can i solve the problem, without loosing data?
how can i remove the 'striped' disk and add the new disk to the raid?

You can't remove a vdev from a pool and a single drive striped is a vdev.

Backup the data elsewhere, destroy the pool, recreate it, copy the data back.

Now I wonder how you ended up here.

Thanks for your reply.

Is there any chance just to move the data from the striped-disk somewhere else? Any way to find what data is on that physical disk?

No, it's not possible, that's not how ZFS works.

 

[ck17]

Ok. i see.

Thanks for the feedback anyway ;)

You can replace the strip disk by putting in a new disk if you have an open sata port then zfs replace it using the gui and offline the bad drive. You will still have this bad pool configuration that you need to address though.

You also can upgrade the stripe disk to a mirror and hope it manages to read most of it.

You can add another disk to the stripe and turn it into a mirror.

Or you can remake the zpool.
