[Gluster-users] invisible files in some directory

[Mauro Tridici]

Dear Users,

I’m facing with a new problem on our gluster volume (v. 3.12.14).
Sometime it happen that “ls” command execution, in a specified directory, return empty output.
“ls” command output is empty, but I know that the involved directory contains some files and subdirectories.
In fact, if I try to execute “ls” command against a specified file (in the same folder) I can see that the file is there.

In a few words:

“ls" command output executed in a particular folder is empty;
"ls filename” command output executed in the same folder is ok.

There is something I can do in order to identify the cause of this issue?

You can find below some information about the volume.
Thank you in advance,
Mauro Tridici
