Thanks for the code. It helped a little bit to understand some details. I tried the "-e" Option of "zdb" and I listed the uberblocks of the = discs with "zdb -l -u <dev>". As I can see, the there is a "create_txg: 56482". With the uberblocks I = was able to find the corresponding date/time which is the time I added = the new vdev. But every command and option combo I'm trying gets me just two results: "Input/output error" or "Device not configured" So I can't read out data via "-bbb" or so... Perhaps there was more destroyed during the process of creating and = adding the new vdev than I thought first. It seems to me, that the = NAS4free GUI mixed up the discs during formatting or something like = that. After adding the new vdev I hat 16TB of space which was way too = much and in the info I could see the discs of the old vdev twice... But = the NAS was still playing out my data. After the restart the pool = faulted. So my last idea is the "-C" option of the "zdb" command. Perhaps I can = give a new config which it has to use. But where do I find the config = file or what is it supposed to look like? I also think there is no way to write new or edit the lables of the = discs?
