[SOLVED] chattr: Operation not supported

chris101.park · 07-15-2015, 04:36 AM

Hi, guys. I am a newbie in this world and studying based on RHEL7. Today I have encountered an error when I tried to put extended file attribute like this;

Code:

[root@host1 user1]# ll file1
-r-xr--r--. 1 user1 user1 1056 Jul 15 18:53 file1
[root@host1 user1]# chattr +c file1
chattr: Operation not supported while setting flags on file1

The file is simple text file and the file system is xfs.

Thanks in advance for any comment and advice.
Have a good day =)

xfs doesn't support chattr compression yet.

Code:

$ man xfs | tail -n21
FILE ATTRIBUTES
       The XFS filesystem supports setting the following file attributes on Linux systems using the chattr(1) utility:

       a - append only
       A - no atime updates
       d - no dump
       i - immutable
       S - synchronous updates

       For descriptions of these attribute flags, please refer to the chattr(1) man page.
