This simple routines talks by itself:

I recently installed e2fsprogs in order to protect some files in my file system against involuntary deletion so i ran

chattr -R +i /home/ape/mnt

, but i repented because i thought that the meassure was too strong, then

chattr -R -i /home/ape/mnt

  in order to

chattr -R -a /home/ape/mnt

but, as the more experienced could notice from the upper code, i had no need of that since the append mode is already compulsively forced by watever is failing on the system or on this user for that hard drive.
The trouble above is that im being unable to delete ANY file even with superuser privileges and even with no flags on the files while on the drive in question.

As you can see from upper, I have an ext4 partition from a different drive than that of the system mounted on /home/ape1/mnt, the partition was recursively marked as inmutable and later unmarked but the practical result was an append only mode just for that hard drive, even when no flags, then as you can notice on the routine, the result of creating a file there is inhability to remove after creation.

Re: Issue with file attributes

The thread is solved, according to your first post, but you are still bumping it? Don't do that:
