Hello, In the logs I don't have any output about problems with the filesystem. Indeed I had a corrupted file after learning about the zpool status -v, but the ones that I can't delete didn't show up. Searching on the web I found that running the command #echo > /path/to/undetelable/file seems to fix the file to become deletable, but Im not sure why the file was stuck in the first place... Taking advantage of the opportunity, where is the best place I can seek advice to solve issues with 3D acceleration with Intel while I have this notebook with Optimus? Thank you for the pacience, Best regards, Mario Em qua, 5 de jun de 2019 =C3=A0s 10:34, Dean E.
