Hello,
I'm new here, because I was always been able to find a way to solve my problems.
But now, it looks different and I need help:?
Following situation: Given was a OMV3/Debian 8 installation with ZFSonLinux, because I had taken over my RAIDZ5 network from FreeNas times.
Last week the SSD failed and I had to reinstall the System, what was in the past never really problematic.
However, I have now the problem that I lost two of my directories (in the pool root) and I don`t know, how can I solve the problem.
The pool was added as in the past also with "zpool import -a", which was also successful this time, up to the fact that I am missing two directories.
The "Zpool status" gives me currently 0 errors as well as approximately the same used memory as before the SSD crash.
Since at least in one of the directories private video recordings were stored, I would be pleased if there is some way to get the data again.
Sincerely and sorry for my bad english 
Torben
