Do you have backups? You must always keep another copy of anything important and irreplaceable.

unfortunately i dont have the backup... i was counting on parity to rebuild the data... but now the parity is invalid (red X).

Disk1 is failing:

197 Current_Pending_Sector  -O---K   100   100   000    -    99

 

And without parity you can't replace it, best bet is to use ddrescue to clone it then run xfs_repair if still needed.
