Hello, 

I am trying to delete a folder in /dbfs/mnt, but I am unable to do so. The folder was an old mounted storage account, which was deleted. The folder contains a single file 'mount.err'.

In command line I tried rm -rf my_folder, with and without sudo. I also tried to rename the folder. 

Whatever I try, I get the following error : rm: cannot remove 'my_folder/mount.err': Input/output error

I also tried in a notebook and with dbutils, but one again without success.

I tried repairing the filesystem with fsck.ext4, without success.

Please let me know if someone has a solution, thank you.
