@itimpithat folder was created when i used my old cache pool
when I restored my appdata it wanted to write there but my new cache pool have a different name
unraid changed the cache drive automaticly when i went in to the share options, but in the shares tab it still wanted to go to the old drive
So I had to manually chanche the cache drives from my shares, let them copy ofcourse to the new pool, and I did a restart
then the error in my system log was gone, so then i removed the folder and contents in terminal
did a restart, and everythink is working fine now
