I have a problem. chattr +e <file> does not work, if the file does not have the +e attr set on it, or if it's removed and re-added.

[root@ip-203-0-113-13 tmp]# chattr +e bar
chattr: No space left on device while setting flags on bar

Waaaaat?

There is plenty of space on the device and plenty of inodes free, so why is chattr +e failing? If it makes a difference, I'm seeing this failure on Fedora 28 on EC2. I'm not seeing on SUSE 42 on EC2 (yet?)

Update:

I ran strace on the command. I'm not sure if it's helpful, but it seems interesting...

If you check the manual this parameter is not suppose to alter, I am surprised you are able to remove, since it is not able to find contiguous area it is showing above error.

extent format (e) […]
The 'e' attribute indicates that the file is using extents for mapping the blocks on disk.
