[Gluster-users] I/O error repaired only by owner or root access

[Rajesh Amaravathi]

Hi Dan,
Could you please provide the following info>
(1) the exact permissions of the file you are accessing and
its parent directory,
(2) the user from which 'ls -l' is issued, and
(3) the owner of the file, and the parent directory.

You could open a bug for it if it is seen several times.

Regards, 
Rajesh Amaravathi,
